Выпущен androidx.compose.ui:ui-*:1.7.0-beta03 . Версия 1.7.0-beta03 содержит эти коммиты .

Версия 1.7.0-бета02

29 мая 2024 г.

Выпущен androidx.compose.ui:ui-*:1.7.0-beta02 . Версия 1.7.0-beta02 содержит эти коммиты .

Изменения API

• SemanticsProperties.Editable переименован в IsEditable и изменен SemanticsPropertyReceiver.editable на значение isEditable . Свойство теперь является логическим и всегда указывается в текстовых полях. ( I8acd8 )
• Переименуйте параметр теста доступности. ( I3d440 )
• Обновлен API для стилизации ссылок: TextLinkStyles теперь является частью конструктора LinkAnnotation и метода AnnotatedString.fromHtml ( I90b2b ). Также удалены TextDefaults из материала ( I5477b ).

Исправления ошибок

• LayoutCoordinates.introducesFrameOfReference переименован в LayoutCoordinates.introducesMotionFrameOfReference чтобы лучше отражать его назначение. Переименована связанная функция для расчета координат на основе этого флага. ( I3a330 )

Версия 1.7.0-бета01

14 мая 2024 г.

Выпущен androidx.compose.ui:ui-*:1.7.0-beta01 . Версия 1.7.0-beta01 содержит эти коммиты .

Изменения API

• performCustomAccessibilityActionLabelled переименована в performCustomAccessibilityActionWithLabel и performCustomAccessibilityActionWhere в performCustomAccessibilityActionWithLabelMatching . ( I5387f )
• AnnotatedString.hasEqualsAnnotations теперь имеет hasEqualAnnotations ( I685c0 ).
• Обновлен API для получения тематических ссылок Material в тексте. В частности, из TextDefaults удалены методы для создания тематических LinkAnnotations и анализа HTML с тематическими ссылками. Вместо этого добавлен класс TextLinkStyles , который позволяет стилизовать ссылки в качестве параметра составного текста. ( I31b93 )

Исправления ошибок

• Исправляет дополнительные случаи использования при динамическом добавлении модификаторов ввода указателя во время событий 63e1504.

Версия 1.7.0-альфа08

1 мая 2024 г.

Выпущен androidx.compose.ui:ui-*:1.7.0-alpha08 . Версия 1.7.0-alpha08 содержит эти коммиты .

Изменения API

• Добавляет поддержку изменяемых реализаций фигур. Shape#createOutline теперь наблюдается внутри графических слоев, поэтому чтение значений состояния внутри приведет к недействительности при изменении состояния, что позволяет создавать более производительную анимацию фигур. ( Id1629 , б / 326070216 )
• Переименован isPositionedByParentWithDirectManipulation , чтобы introducesFrameOfReference . Обратите внимание, что теперь это имеет обратный эффект: по умолчанию большинство LayoutCoordinates вводят систему отсчета, и только при прямом манипулировании свойство будет иметь значение false. Чтобы запросить позицию только тех, которые вводят систему отсчета, используйте positionInLocalFrameOfReference(...) . Или positionInLocalLookaheadFrameOfReference из LookaheadScope . ( Ifc5f7 )
• API-интерфейсы LookaheadScope стали стабильными ( I21507 ).
• Измените лямбду действия для getScrollViewportLength в соответствии с отзывами совета API. ( Ibc74a )
• Обновлены API-интерфейсы структуры GraphicsLayer для использования параметров с плавающей запятой вместо int. Удалены дозорные значения UnsetOffset/UnsetSize IntSize в пользу уже существующих констант Unspecified во встроенных классах Offset и Size на основе плавающей запятой ( I2fb03 , b/333863462 ).
• При вводе ввода мыши во время тестов MouseInjectionScope.click() , MouseInjectionScope.doubleClick() , MouseInjectionScope.tripleClick() , MouseInjectionScope.longClick() теперь принимают параметр button: MouseButton чтобы сделать их более универсально применимыми. Значением по умолчанию для всех методов является MouseButton.Primary . ( I31a23 , б / 190493367 , б / 261439695 )
• Переименован onClicked в onClick внутри LinkInteractionListener . ( Iaa35c )
• Переименуйте TextInclusionStrategy.isInside в isIncluded . Сделайте тип возвращаемого значения Paragraph/MultiParagraph#getRangeForRect() не допускающим значения NULL. ( I51f26 )

Исправления ошибок

• Исправлен длинный снимок экрана для прокручиваемых контейнеров с reverseScrolling=true . ( I7c59c )

Внешний вклад

• Добавлена ​​поддержка предварительной выборки элементов во вложенных LazyLists (например, LazyColumn который отображает вложенные LazyRows ). Ожидается, что это изменение уменьшит выпадение кадров во время прокрутки для этих LazyLists . По умолчанию реализация выполняет предварительную выборку первых двух вложенных элементов, однако этим поведением можно управлять с помощью новых API LazyLayoutPrefetchStrategy(nestedPrefetchItemCount) и LazyListPrefetchStrategy#onNestedPrefetch . ( I51952 )

Версия 1.7.0-альфа07

17 апреля 2024 г.

Выпущен androidx.compose.ui:ui-*:1.7.0-alpha07 . Версия 1.7.0-alpha07 содержит эти коммиты .

Изменения API

• ClickableText помечен как устаревший. Чтобы добавить ссылки в текст, создайте AnnotatedString с LinkAnnotation соответствующим вашей ссылке, и передайте эту AnnotatedString в составной элемент Text. ( I34d4b , б/323346994 )
• Представьте ViewConfiguration.HandwritingGestureLineMargin для жестов рукописного ввода. Поддержка жеста JoinOrSplit для BasicTextField ( Ie6e13 , b/325660505 )
• FocusProperties.enter и FocusProperties.exit больше не являются экспериментальными. FocusDirection.Enter и FocusDirection.Exit больше не являются экспериментальными. FocusRequester.Cancel больше не является экспериментальным ( I461a1 , b/261564106 ).
• При запросе координат макета теперь вы можете использовать аргумент excludeDirectManipulationOffset , чтобы исключить смещение, установленное родительскими макетами, которые разместили своих дочерних элементов с помощью Placeable.PlacementScope.withDirectManipulationPlacement . Аналогично, макет, который часто меняет положение своих дочерних элементов, теперь может размещать их с помощью withDirectManipulationPlacement (например, Scroll, реализованного по умолчанию). Это помогает анимации, основанной на approachLayout стать более интуитивно понятными, поскольку теперь у вас есть возможность различать, какое смещение нужно анимировать, а что применять непосредственно при принятии решения о анимации их подхода. ( I60ec7 )
• Флаг функции для длинных снимков экрана был удален. ( I28648 , б/329128246 )
• LazyColumn теперь правильно отображает прикрепленные заголовки на длинных скриншотах. ( I8d239 , б/329296635 )
• Источники NestedScroll Drag и Fling заменяются UserInput и SideEffect , чтобы обеспечить расширенное определение этих источников, которые теперь включают анимацию (Side Effect) и колесо мыши и клавиатуру ( UserInput ). ( I40579 )
• ApproachLayoutModifierNode и Modifier.approachLayout теперь стабильны, а новые isMeasurementApproachInProgress() и isPlacementApproachInProgress() заменяют старые isMeasurementApproachComplete() и isPlacementApproachComplete() соответственно.
• Удален устаревший модификатор intermediateLayout . ( I3e91c )
• Переименуйте GraphicsLayer#buildLayer для записи, чтобы отразить методы Begin/EndRecording API-интерфейсов, поддерживаемых Displaylist, таких как RenderNode и Picture.
• Обновлен rememberGraphicsLayer для использования rememberObserver . ( I312c1 , б / 288494724 , б / 330758155 )
• UrlAnnotation устарел, используйте вместо него LinkAnnotation.Url . Если вы используете тему Material, используйте объект TextDefaults для создания аннотации с примененной к ней темой Material ( I8d180 , b/323346545 ).
• Текстовые ссылки получили опцию стиля нажатого состояния в дополнение к обычному стилю, наведению курсора и фокусу ( I5f864 , b/139312671 ).
• String.parseAsHtml переименован в AnnotatedString.Companion.fromHtml . ( I43dcd )
• В метод parseAsHtml добавлены аргументы стиля ( linkStyle , focusedLinkStyle , hoveredLinkStyle ) и прослушиватель взаимодействия ссылок. При анализе строки с HTML-тегом с помощью тегов <a> метод создает LinkAnnotation.Url для каждого такого тега и передает объекты стиля и прослушиватель взаимодействия ссылок в каждую аннотацию. ( I7c977 )
• LinkAnnotation теперь принимает аргументы стиля на основе состояния и LinkInteractionListener . Добавьте эту аннотацию в AnnotatedString чтобы получить гиперссылку. Передавая focusedState и/или hoveredState вы можете определить визуальную configuration ссылок, когда они находятся в фокусе и/или наведены. ( I81ce4 , б/139312671 )
• ImeOptions.hintLocales больше не имеет значения NULL. Если вы хотите передать пустой список локалей, используйте LocaleList.Empty . ( Ic5bc4 )

Исправления ошибок

• Грамотно обрабатывает неверные/поврежденные исторические данные входных событий (игнорирует неправильные данные смещения).
• Исправляет непредвиденные события указателя, когда модификатор ввода указателя добавляется динамически перед другим модификатором ввода указателя во время активного потока событий ввода указателя (например, между вводом при наведении и выходом при наведении [мышь/стилус]).

Версия 1.7.0-альфа06

3 апреля 2024 г.

Выпущен androidx.compose.ui:ui-*:1.7.0-alpha06 . Версия 1.7.0-alpha06 содержит эти коммиты .

Новые возможности

• Добавлен метод parseAsHtml для стилизованных строк: он позволяет конвертировать строку, помеченную HTML-тегами, в AnnotatedString . Обратите внимание, что не все теги поддерживаются, например, вы пока не сможете отображать маркированные списки. ( I84d3d , I30626 , б/139326648 )
• Реализована экспериментальная поддержка длинных снимков экрана в контейнерах прокрутки Compose с использованием официального API Android ( ScrollCaptureCallback ). Эта функция является экспериментальной и в настоящее время может обрабатывать не все случаи правильно. По этой причине в настоящее время по умолчанию он отключен. Чтобы принять участие, установите для флага ComposeFeatureFlag_LongScreenshotsEnabled значение true. ( I2b055 , б/329296471 )

Изменения API

• fun ClipEntry.getMetadata() заменено на val ClipEntry.clipMetadata . ( I50155 )
• Удалены функции ClipboardManager.getClipMetadata и ClipboardManager.hasClip . Используйте clipEntry.getMetadata() для чтения метаданных текущей записи клипа. Также проверьте результат ClipboardManager.getClip , если он равен нулю или нет, чтобы понять, есть ли в буфере обмена текущий клип. ( I50498 )
• Теперь вы можете передавать объекты GraphicsLayer в функции placeable.placeWithLayer() ( I1b22f ).
• ClipboardManager.setClip теперь принимает значение null, чтобы иметь возможность очистить буфер обмена. ( I7d2e9 )
• Добавлены идентификаторы ресурсов для помощи в сокрытии представлений, используемых в качестве деталей реализации в инструментах сборки ( I99531 ).
• Добавлен метод приостановки GraphicsLayer#toImageBitmap для поддержки рендеринга содержимого растрового изображения в GraphicsLayer . Это операция рендеринга с аппаратным ускорением на уровне API 22+ (включительно), которая поддерживает более 99% всех устройств Android. На уровне Android API 21 это возвращается к программному рендерингу. ( I9e114 )
• Вспомогательный метод для преобразования Android RectF в ComposeRect ( I39925 , b/325660505 )
• Все параметры KeyboardOptions теперь по умолчанию имеют неопределенное значение. Добавлен метод KeyboardOptions.merge .
• KeyboardOptions.autoCorrect переименован в autoCorrectEnabled и сделал его допускающим значение NULL, где значение NULL означает, что значение не было указано. ( Ia8ba0 , б/295951492 )
• Вариант BasicTextField(state) и BasicSecureTextField теперь используют KeyboardActionHandler вместо KeyboardActions для обработки действий, выполняемых программной клавиатурой. ( I58dda )

Версия 1.7.0-альфа05

20 марта 2024 г.

Выпущен androidx.compose.ui:ui-*:1.7.0-alpha05 . Версия 1.7.0-alpha05 содержит эти коммиты .

Новые возможности

• Внедрите новый API GraphicsLayer для записи команд рисования в список отображения, а также дополнительных свойств, влияющих на отрисовку списка отображения. Это обеспечивает границу изоляции, позволяющую разделить сложную сцену на более мелкие части, которые можно обновлять индивидуально друг от друга, не пересоздавая всю сцену. Преобразования, выполненные в GraphicsLayer можно выполнить без перезаписи списка отображения. В отличие от Modifier.graphicsLayer , GraphicsLayer позволяет отображать составной контент в другом месте и полезен в случаях использования анимации, когда ожидается, что контент будет отображаться в разных сценах.

Изменения API

• GraphicsLayer.draw(Canvas) больше не является общедоступным API. Вместо этого используйте функцию расширения DrawScope.drawLayer(GraphicsLayer) для рисования слоя. ( I7a7c0 )
• Разделите restrictedConstraints() на два метода: fitPrioritizingWidth() и fitPrioritizingHeight() ( I6d7fd ).
• Представлена ​​заглушка HardwareCanvas для использования Android L ( I1c3b5 , b/288494724 ).
• Обновите структуру Compose, чтобы предоставить локальную композицию GraphicsContext , а также обновить реализации модификаторов Owner, DelegateableNode и drawWithCache чтобы предоставить доступ к GraphicsContext для ограниченного доступа, который будет автоматически очищать экземпляры GraphicsLayer при удалении модификаторов. ( I64a2f , б / 288494724 )
• Представлен InterceptPlatformTextInput для помощи в написании низкоуровневых тестов, связанных с IME, и других низкоуровневых вариантов использования IME. PlatformTextInputTestOverride устарел. ( I862ed , б/322680547 )
• Добавлена ​​функция расширения GraphicsLayer.setOutline(Outline) . ( Ib81f4 )
• Представьте конструктор функции GraphicsContext для создания фабрики для создания экземпляров GraphicsLayer ( Ib98d6 , b/288494724 ).
• Открытый API GraphicsLayer , обеспечивающий определенную разработчиком гибкость при захвате команд рисования, которые можно использовать для рисования в другом месте, а также применения различных визуальных эффектов к конечному результату. ( I80245 , б / 288494724 )
• Представьте Paragraph#getRangeForRect , который возвращает диапазон текста, охватываемый заданной областью прямоугольника. ( Iee516 , б/325660505 )
• Удалено экспериментальное переопределение BasicText с аргументом onLinkClicked . В будущем появится замена API для поддержки гиперссылок. ( I107d5 )

Исправления ошибок

• Добавлено определение ожидаемого/фактического API GraphicsLayer для поддержки захвата и воспроизведения команд рисования с дополнительными визуальными эффектами и преобразованиями композиции. Представьте интерфейс GraphicsContext для хранения графических зависимостей, включая создание экземпляров GraphicsLayer и управление ими. ( I4a8d6 , б/288494724 )
• Исправлена ​​проблема взаимодействия с одномерным поиском фокуса, из-за которой фокус застревал внутри ComposeView , встроенного среди других представлений. ( I08fd4 )

Внешний вклад

• LocalLifecycleOwner перешел от пользовательского интерфейса Compose к lifecycle-runtime-compose , чтобы его вспомогательные API на основе Compose можно было использовать за пределами пользовательского интерфейса Compose. Спасибо Джейку Уортону за вклад. ( I6c41b , б/328263448 )
• Последовательно раскрывайте свойства смещения с плавающей запятой для всех подтипов выравнивания на основе смещения. ( I69f0f , б/328088992 )

Версия 1.7.0-альфа04

6 марта 2024 г.

Выпущен androidx.compose.ui:ui-*:1.7.0-alpha04 . Версия 1.7.0-alpha04 содержит эти коммиты .

Изменения API

• Поддержка функции рукописного ввода стилусом для BasicTextField2 на устройствах после Android U. ( I002e4 )
• В этом CL мы добавляем семантическое действие GetScrollViewportLength , чтобы мы могли передавать информацию о компонентах, прокручиваемых в композиции, в систему a11y. Этот CL также применяет использование указанного свойства в прокручиваемых списках Foundation. ( Ic5fa2 )
• FocusRequester.createRefs теперь стабилен ( I4d92c , b/261436820 )
• Введен DelegatableNode.requireView() позволяющий узлам-модификаторам получать текущее View Android без чтения локальной композиции. ( I40768 )
• Новый API Path.reverse() для изменения направления пути ( I36348 ).
• В KeyboardOptions добавлены hintLocales , чтобы предоставить TextFields возможность указывать IME с определенными языковыми стандартами для установки предпочтительного языка.
• Предоставьте свойство platformLocale из Locale , которое возвращает базовый объект платформы, например java.util.Locale . ( I921c6 )

Версия 1.7.0-альфа03

21 февраля 2024 г.

Выпущен androidx.compose.ui:ui-*:1.7.0-alpha03 . Версия 1.7.0-alpha03 содержит эти коммиты.

Изменения API

• Представляем ContextualFlowRow и расширенный FlowRow / Column с MaxLines и Overflow. Мы рады объявить об улучшениях экспериментальных FlowRow и FlowColumn , которые теперь включают поддержку maxLines и переполнения, а также дебют ContextualFlowRow и ContextualFlowColumn . Это обновление предназначено для обеспечения компонентов с оптимальной производительностью, где ContextualFlow* идеально подходит для большого количества элементов, используя небольшую конфигурацию maxLines и динамические кнопки +N, чтобы увидеть больше, а FlowRow и FlowColumn идеально подходят для небольшого количества элементов, меньше более 100 предметов. Важно: Чтобы сохранить существующее поведение в FlowRow или FlowColumn , где все элементы составлены независимо от того, соответствуют ли они максимальному значению поперечной оси, задайте для overflow FlowRowOverflow.Visible или FlowColumnOverflow.Visible во время инициализации. Изучите ContextualFlowRowSample и FlowRowSample чтобы увидеть примеры этих новых функций в действии. ( Ib9135 , б / 293577082 )
• Добавьте семантическое свойство maxTextLength , которое должно быть установлено в текстовых полях, которые фильтруют максимально допустимое количество символов. ( I24d9f , б / 170648072 )
• Обертка Modifier.inspectable устарела. Этот API создаст больше недействительных модификаторов, чем необходимо, поэтому его использование теперь не рекомендуется. Разработчикам рекомендуется реализовать метод inspectableProperties() в ModifierNodeElement если они хотят предоставить свойства модификатора инструментам. ( Ib3236 )
• Новый конструктор PopupProperties , который позволяет полностью контролировать флаги WindowManager.LayoutParams . ( Ibb33e , б/312485503 )
• Представлен DelegatableNode.requireLayoutCoordinates() как способ получить текущие LayoutCoordinates Modifier.Node без необходимости переопределять onPlaced и самостоятельно сохранять координаты в свойстве. ( Ia8657 )
• Представлен DelegatableNode.currentLayoutCoordinates как способ получить текущие LayoutCoordinates Modifier.Node без необходимости переопределять onPlaced и самостоятельно сохранять координаты в свойстве. ( Иаэбаа )
• BasicTextField2 и связанные API из пакета androidx.compose.foundation.text2 перемещены в androidx.compose.foundation.text . ( I9f635 )
• Добавлен новый API ApproachLayoutModifierNode для поддержки создания пользовательской логики подхода в явном узле модификатора. Также добавлен новый экспериментальный API DeferredTargetAnimation для анимаций, цель которых неизвестна при создании экземпляра. ( I60745 )
• Новые API-интерфейсы Path для запроса направления Path и извлечения контуров из Path . ( I63d04 )

Изменение поведения: включение FontPadding теперь ложно по умолчанию в Compose

includeFontPadding теперь является ложным по умолчанию ( 21D806 ) в Compose.

includeFontPadding - это устаревший атрибут, который контролирует, следует ли включать дополнительную заполнение поверх первой строки и последнюю строку текста, чтобы вместить любые символы, которые могут расширяться выше или ниже базовых линий текста.

Обновление этой версии Compose изменит то, как все тексты рендеринг в вашем пользовательском интерфейсе, удалив дополнительную заполнение поверх первой строки и последнюю строку каждого отображения, который вы отображаете.

В зависимости от требований вашего пользовательского интерфейса и метрик шрифтов, которые вы используете, изменения должны быть минимальными. Однако вы могли бы встретить блокаторы, такие как: - Сломанные тесты экрана. Исправьте пользовательский интерфейс, если необходимо, и восстановите золотые изображения. - Текст немного смещен. Удалите любые пользовательские отрицательные наборы или добавьте накладку, если это необходимо.

Вы можете включить includeFontPadding с помощью PlatformTextStyle для каждого текста:

Text(
 text = myText,
 style = TextStyle(
   lineHeight = 2.5.em,
   platformStyle = PlatformTextStyle(
     includeFontPadding = true/false
   )
   /* … */
  )
)

Вы можете включить includeFontPadding для всех ваших текстов, настраивая ваши материалы. Обратите внимание, что имена параметров будут варьироваться между M2 и M3.

val Typography = Typography(
   body1 = TextStyle(
       fontFamily =    /* … */,
       fontSize =    /* … */,
       platformStyle = PlatformTextStyle(
           includeFontPadding = false
       )
   /* … */
   )
)

MaterialTheme(
   typography = Typography,
   /* … */
)

Вы можете узнать больше о Compose includeFontPadding в документацию разработчика и в этом блоге .

Version 1.4.0-alpha03

December 7, 2022

androidx.compose.ui:ui-*:1.4.0-alpha03 is released. Version 1.4.0-alpha03 contains these commits.

API Changes

• Removing ExperimentalComposeUiApi from PointerIcon ( I23af8 )
• Introduce Page accessibility actions: PageUp , PageDown , PageLeft , PageRight . Note that these are only available from API 29. ( Ida4ab )
• Updated rememberNestedScrollConnection parameter view from root view to host view. ( Ia5200 )
• Added an Modifier API to query ancestors scroll info. ( I2ba9d , b/203141462 )
• Used in Clickable to correctly delay press interactions, when gestures could become scroll events.
• Fixed Clickables not correctly delaying ripples, when used inside an Scrollable ViewGroup .
• Updated Drawers and Sheets to correctly delay presses in case gestures can become scroll events.
• Renamed CompositingStrategy.Always to Offscreen to indicate that the graphicsLayer will always be rendered into an intermediate buffer ( I47dc1 )
• Layout overload with multiple content slots is now stable ( I10566 , b/248294649 )
• Added experimental new APIs PerfettoTrace.record {} and PerfettoTraceRule to capture Perfetto traces (also known as System Traces) as part of a test, to inspect test behavior and performance. ( I3ba16 )
• In UI tests using a Compose rule, continuations resumed during withFrameNanos callbacks will not be dispatched until after all frame callbacks have finished running. This matches the behavior of compose when running normally. However, tests that rely on the old behavior may fail. This should only affect code that calls withFrameNanos or withFrameMillis directly, and has logic outside of callback passed to those functions that may need to be moved inside the callbacks. See the animation test changes in this CL for examples.
• Added optional onPerformTraversals: (Long) -> Unit parameter to TestMonotonicFrameClock constructor and factory function to run code after withFrameNanos callbacks but before resuming callers' coroutines. ( Idb413 , b/254115946 , b/222093277 , b/255802670 )
• Added EmojiCompat to Compose ( Ibf6f9 , b/139326806 )

Dependency Updates

• Compose UI and Compose Material now depend on Lifecycle 2.5.1. ( I05ab0 , b/258038814 )

Version 1.4.0-alpha02

November 9, 2022

androidx.compose.ui:ui-*:1.4.0-alpha02 is released. Version 1.4.0-alpha02 contains these commits.

API Changes

• Updated GraphicsLayerScope to expose the current size of the graphicsLayer . This is useful for computing graphicsLayer transformations as a function of the Composable size. ( If8c43 , b/181387080 )
• Introduced CompositingStrategy to determine when to leverage an offscreen compositing layer for rendering of graphicsLayer content. Auto maintains the default behavior which internally leverages a layer if alpha is applied or a RenderEffect/Overscroll . Always will always introduce an offscreen buffer where ModulateAlpha will avoid leveraging an offscreen buffer and instead will modulate each of the recorded drawing instructions within the graphicsLayer . ModulateAlpha usage will still leverage an offscreen buffer for RenderEffect/Overscroll usages ( I25e82 , b/256382834 )
• invalidateSubtree() was added to Modifier.Node to allow invalidating entire hierarchies for layout and drawing. ( I4bd90 )
• Promote rememberNestedScrollInteropConnection to stable. Introduced the ability to pass a root view to rememberNestedScrollInteropConnection . This can help the custom view better react to scrolling constraints, specially in non-standard views (eg ModalBottomSheetDialog ). ( I9e107 )
• Added ObserverNode interface that can be used by Modifier.Node implementations that need to be notified when a value that they had previously read has changed ( I5728b , b/247716483 )
• Added a new constructor to Paint that accepts a native android.graphics.Paint . Also added an extension function toComposePaint() that converts an existing native Paint object to Compose Paint. ( Ica91b )
• Add new FontFamily.Resolver.resolveAsTypeface for use on Android. ( I8950b )
• Add ToolingState to allow tooling to change internal states of Composable ( Ie6614 )
• Refactor tooling to have better support for new added animations ( I8677b )
• Added minLines parameter into material and material3 Text, TextField and OutlinedTextField which allows setting the minimum height of the component in terms of number of lines ( I4af1d )

Version 1.4.0-alpha01

24 октября 2022 г.

androidx.compose.ui:ui-*:1.4.0-alpha01 is released. Version 1.4.0-alpha01 contains these commits.

API Changes

• A new method, awaitEachGesture() , for gesture detectors was added. It operates similar to forEachGesture() , but the loop over gestures operates entirely within the AwaitPointerEventScope so events can't be lost between iterations.
• forEachGesture() has been deprecated in favor of awaitEachGesture() because it allows events to be lost between gestures. ( Iffc3f , b/251260206 )
• Deprecating recycling of acccessibility objects in androidx. We've found performance changes to be negligible in even the oldest supported versions. ( I0a961 )
• Added DrawStyle as an Experimental attribute to TextStyle and SpanStyle to enable drawing outlined text. ( If24b8 , b/155421273 )
• AnnotatedString.Builder now implements kotlin.text.Appendable . ( I1a061 , b/231030444 )
• AnnotatedString.Builder now has an append(AnnotatedString, start: Int, end: Int) method to append a substring of an AnnotatedString and the intersecting styles.

Version 1.3.0-beta01

August 24, 2022

androidx.compose.ui:ui-*:1.3.0-beta01 is released. Version 1.3.0-beta01 contains these commits.

Modifier Node Refactor

The layer which handles Modifier/Modifier.Element instances and coordinates their behavior on LayoutNodes has been majorly refactored. As it stands this was a refactor which did not affect the public API of any of the many modifiers in Compose, and can be viewed as an implementation-only change. Despite that, this is an important change for various reasons. ( Ie4313 )

Change Summary

The added experimental Modifier.Node APIs provide an abstraction that allows for state to be maintained on an instance that will be retained with the lifecycle of the layout node, and will be allocated per-layout-node and per-usage of the corresponding Modifier.Element that produced it.

Broadly speaking, this abstraction provides an alternative mechanism to produce stateful modifiers without relying on the mechanics of the Modifier.composed API.

Риск

This change is strictly binary compatible with prior releases, and is intended to be backwards compatible in terms of observable behavior as much as practical and reasonable. That said, there are few subsystems of compose this refactor did not touch, and it is likely that behavior has changed in ways that were not covered by our tests and have not yet been found and fixed .

Please upgrade to this release with caution. If you believe this has broken something for you, please let us know.

Experimental APIs

Various experimental APIs have been added, all relating to the new concept of a "Modifier Node". Modifier.Node's are created as a result of

• fun modifierElementOf(…): Modifier
• abstract class ModifierNodeElement
• abstract class Modifier.Node
• abstract class DelegatingNode
• interface LayoutModifierNode
• interface DrawModifierNode
• interface SemanticsNode
• interface PointerInputNode
• interface ModifierLocalNode
• interface ParentDataModifierNode
• interface LayoutAwareModifierNode
• interface GlobalPositionAwareModifierNode
• interface IntermediateLayoutModifierNode

Behavior breaking change

Maximum supported elevation in dialogs and popups has been reduced to 8dp.

The maximum supported elevation for Compose dialogs and popups has been reduced from 30dp to 8dp. This change affects both material and ui custom dialogs and popups. This change is made to mitigate an accessibility bug on Android versions below S, and to ensure that accessibility services within those windows are able to interact with the content inside the dialog or popup.

You will only be impacted by this change if you are creating a custom dialog or popup implementation with an elevation set to levels higher than 8dp. Consider lowering the elevation of your dialog or popup. If you need to opt-out from this new behavior, consider forking your own dialog or popup with the desired elevation set. This is not recommended, as accessibility might be negatively impacted and it is on the developer to ensure the bottom part of the dialog or popup is interactable and readable by accessibility services.

API Changes

• Fixed an issue where painterResource wouldn't update on configuration changes ( I58e73 , b/228862715 )
• rememberTextMeasurer no longer takes FontFamily.Resolver , Density , or LayoutDirection parameters. Please use the TextMeasurer constructor to provide custom values for these parameters. ( Ia1da3 )
• Added DialogProperties.decorFitsSystemWindows property to allow Dialogs to support WindowInsets . ( I57742 , b/229378542 )
• Moved font constructors back to original kotlin file to retain binary compatibility. No change from last stable release. ( Ieb2f3 )
• Removed unnecessary operator from several equals definitions - this has no effect. ( I6c309 )
• FontVariation.Setting is a sealed interface, to allow future clamping APIs. ( I11021 , b/143703328 )
• Add CompositionGroup.findParameters to SlotTree.kt . This allows tools to retrieve parameters for a CompositionGroup without having to parse the entire slot table. ( I124fe )

API Changes

• LayoutCoordinates.findRootCoordinates() is now public ( I7fa37 , b/204723384 )
• Added experimental API to get the LayoutCoordinates in the PlacementScope . This lets developers know where the current layout is to place children relative to its position. ( I5482b , b/238632578 )
• Added LayoutCoordinates.transformFrom to get the Matrix transformation from one LayoutCoordinates to another. ( Ic5ab1 , b/238632578 )
• Deprecated SemanticsModifier.id and moved the semantics id to LayoutInfo.semanticsId instead. ( Iac808 , b/203559524 )
• Resource Fonts now support setting font variation settings (API 26+). ( I900dd , b/143703328 )

• Paragraph is now expect|actual and defined for Android and Desktop. ( Id387e , b/239962983 )
• Interface Paragraph is now sealed interface Paragarph. There is no use case for subclassing paragraph, and we recommend reaching out if this change impacts you. ( If5247 , b/239962983 )
• Removed experimental annotation from PlatformTextStyle and LineHeightStyle . ( I64bef )
• Deprecate TextInputService.show|hideSoftwareKeyboard . Please use SoftwareKeyboardController instead in app code and TextInputSession in IME-management code. ( I14e4c , b/183448615 )

API Changes

• Added a new property PointerInputChange#pressure to retrieve the pressure. ( I45a5e , b/205164819 )
• Added rememberTextMeasurer to easily create and remember TextMeasurer instances in composition. ( I8d66e )
• Rect , RoundRect , and MutableRect now support the Kotlin in syntax for calling the contains function. ( Ie42b0 , b/238642990 )

• Added toStringForLog() method to EditCommand to help troubleshoot text editing issues. ( I53354 , b/228862731 )
• Added drawText extension function on DrawScope to provide a way to draw multi-styled text on composables and modifiers that operate on a DrawScope like Canvas and drawBehind . ( I16a62 , b/190787898 )
• Introduce a new experimental API called TextMeasurer that enables arbitrary text layout computation that creates identical results to BasicText , independent from Compose runtime. ( I17101 )
• Add mapTree to SlotTree.kt . This allows tools to inspect the SlotTree without making an in memory copy first like asTree does. For the Layout Inspector this gives a performance improvement of about a factor 10. ( I5e113 )
• Changed Compose Preview to be stored in binary output files, in order to allow developers to write and reuse MultiPreview annotations from libraries. ( I85699 , b/233511976 )

Исправления ошибок

• When adding InputEventChange events to Velocity Tracker we will consider now deltas instead of positions, this will guarantee the velocity is correctly calculated for all cases even if the target element moves ( Icea9d , b/216582726 , b/223440806 , b/227709803 )
• Fix NPE caused by AnnotatedString.toUpperCase when annotations are present. ( I0aca2 , b/210899140 )

Version 1.3.0-alpha01

June 29, 2022

androidx.compose.ui:ui-*:1.3.0-alpha01 is released. Version 1.3.0-alpha01 contains these commits.

API Changes

• New LookaheadLayout that supports a lookahead pass before the actual measure/layout. This allows a pre-calculation of the layout when it changes, while permitting the post-lookahead measure/layout to use the pre-calculated size/position to animate the size and positions towards the target. SubcomposeLayouts are not yet supported, but will be in an upcoming release. ( I477f5 )
• Add optional alpha parameter to Brush flavor of TextStyle and SpanStyle to modify opacity of the whole Text . ( Ic2fac , b/234117635 )
• Introduced the UrlAnnotation annotation type and associated methods to support TalkBack link support in AnnotatedString s. ( I1c754 , b/231495122 )
• Moving utility functionality to runtime ( I4f729 )

Исправления ошибок

• TextLayoutResult.getLineForOffset does not throw. ( Idc5d6 , b/235876324 )

API Changes

• Interfaces in compose libraries are now built using jdk8 default interface methods ( I5bcf1 )
• Added higher-order functions to KeyInjectionScope for injecting key presses while other keys are held down or toggled on. These functions include withKeysDown , withKeysToggled etc. Also added properties for checking if a particular meta key is down, for example, isCtrlDown to check if either control key is depressed. Refer to KeyInjectionScope for documentation on each function. ( I9f6cd , b/229831515 )
• An experimental OverscrollEffect has been introduced to allow for custom overscroll effects, alongside the Modifier.scrollable overloads that accept it.
• Experimental LocalOverScrollConfiguration has been moved from foundation.gesture to foundation package and renamed to LocalOverscrollConfiguration ( If19fb , b/204650733 )

API Changes

• Added pressKeyTimes as well as isCapsLockOn and friends to KeyInjectionScope . Additionally, the API now supports mouse and keyboard combined injection patterns such as clicking a mouse button with a meta key held down. ( I4c8da , b/229831515 )
• Added experimental support for injecting key events. Use performKeyInput to send key events, or send them through the key property of MultiModalInjectionScope during a multi modal input gesture with performMultiModalInput . See KeyInjectionScope for documentation of the API. ( Ic5000 , b/229831515 )
• Add new GoogleFont.Provider.AllFontsListUri for retrieving the canonical internet source of Google Fonts supported by Android.
• Improve error messages rethrown when GoogleFonts fail to load in compose. ( I0416c )

Исправления ошибок

• When adding InputEventChange events to Velocity Tracker we will consider now deltas instead of positions, this will guarantee the velocity is correctly calculated for all cases even if the target element moves ( I51ec3 , b/216582726 , b/223440806 , b/227709803 )
• The Show Layout Bounds setting will now be applied for composables immediately after toggling it from the quick settings tile, without having to leave and re-enter the activity. ( I843d5 , b/225937688 )
• Accessibility string lookup does not trigger font loading. Previously, it would attempt to load fonts for StyleSpans , which lead to crashes if FontFamily.Resolver had been overwritten. ( I4609d )
• Pressing the forward delete key when the cursor is at the end of a text field will no longer crash.
• DeleteSurroundingTextCommand and DeleteSurroundingTextInCodePointsCommand now require their constructor arguments to be non-negative. ( Ica8e6 , b/199919707 )

Version 1.2.0-beta02

API Changes

• Reusing functionality in other preview types ( I19f39 )

Исправления ошибок

• ViewCompositionStrategy.DisposeOnDetachedFromWindowIfNotInPoolingContainer has been renamed to DisposeOnDetachedFromWindowOrReleasedFromPool to better reflect that when disposals do occur, rather than simply when they do not occur. ( If15ca )

Version 1.2.0-beta01

May 11, 2022

androidx.compose.ui:ui-*:1.2.0-beta01 is released. Version 1.2.0-beta01 contains these commits.

Новые возможности

• This is the first beta release of 1.2!

API Changes

• Added experimental BeyondBoundsInterval that can be used by custom implementations of LazyList when they layout items beyond visible bounds ( Ifabfb , b/184670295 )
• Keyed versions of Modifier.composed are now stable API ( Ie65e4 , b/229988420 )
• Simplified the rememberNestedScrollConnection API to use composition locals to acquire the current view information ( I67ca7 )
• The @ComposableTarget annotation and annotations marked by @ComposableTargetMarker can now be used at the file scope using the @file prefix. Using a target annotation at the file scope will cause the compiler to assume all composable functions in the file are intended to be target the associated applier. For example, using @file:UiComposable declares that all @Composable functions target the Compose UI applier. A function that needs to target another applier must explicitly supply the target marker annotation for the desired applier. ( I40804 )

• Introduced new experimental, platform independent, test API: an interface ComposeUiTest and a fun runComposeUiTest(block: ComposeUiTest.() -> Unit) , that can be used to run Compose Ui tests without the need for a TestRule . To run a test without a ComposeTestRule , pass the test as a lambda to runComposeUiTest , and use the methods and members in the receiver scope ComposeUiTest , which are the same ones as in ComposeContentTestRule .

  The Android specific interface AndroidComposeUiTest and fun runAndroidComposeUiTest(block: AndroidComposeUiTest.() -> Unit) are added to provide access to the underlying Activity, similar to AndroidComposeTestRule . For even more control, you can instantiate a class AndroidComposeUiTestEnvironment yourself.

  The Desktop implementation is the class DesktopComposeUiTest , but no Desktop specific run functions are offered at the moment.

  Migrating a test from a ComposeTestRule to ComposeUiTest can be done like this (Android example). От:

  @RunWith(AndroidJUnit4::class)
  class MyTest {
      @get:Rule val rule = createComposeRule()
      @Test
      fun test() {
          rule.setContent {
              Text("Hello Compose!")
          }
          rule.onNodeWithText("Hello Compose!").assertExists()
      }
  }
  

  К:

  @RunWith(AndroidJUnit4::class)
  class MyTest {
      @Test
      @OptIn(ExperimentalTestApi::class)
      fun test() = runComposeUiTest {
          setContent {
              Text("Hello Compose!")
          }
          onNodeWithText("Hello Compose!").assertExists()
      }
  }
  

• For now, ComposeContentTestRule and ComposeTestRule don't extend from ComposeUiTest , which means extension functions on ComposeUiTest can't be called yet on the TestRule interface. When ComposeUiTest graduates to stable API, ComposeContentTestRule and ComposeTestRule will be changed to extend from ComposeUiTest . ( Ib4e90 )

• LineHeightBehavior is renamed as LineHeightStyle

• LineVerticalAlignment is renamed as LineHeightStyle.Alignment

• Renames LineHeightTrim is renamed as LineHeightStyle.Trim

• Default constructor values from LineHeightStyle is removed ( I582bf , b/181155707 )

• Added Brush to TextStyle and SpanStyle to provide a way to draw text with gradient coloring. ( I53869 , b/187839528 )

• trimFirstLineTop , trimLastLineBottom attributes of LineHeightBehavior changed into a single enum: LineHeightTrim . LineHeightTrim have values of 4 states defined by two booleans: FirstLineTop , LastLineBottom , Both and None ( Ifc6a5 , b/181155707 )

• Added LineHeightBehavior to the TextStyle and ParagraphStyle . LineHeightBehavior controls whether line height is applied to the top of the first line and to the bottom of the last line. It also defines the alignment of line in the space provided by TextStyle(lineHeight) .

  For example it is possible to get a behavior similar to what CSS defines via LineHeightBehavior(alignment = LineVerticalAlignment.Center, trimFirstLineTop=false, trimLastLineBottom = false) .

• trimFirstLineTop , trimLastLineBottom configurations works correctly only when includeFontPadding is false. ( I97332 , b/181155707 )

• PlatformParagraphStyle.lerp and PlatformSpanStyle.lerp functions are changed to be top level functions ( I9a268 )

Исправления ошибок

• PointerInputChange::copy documentation now correctly states that it is a shallow copy. ( I182f5 )
• Support ellipsis when height is limited and doesn't fit all text lines ( Ie528c , b/168720622 )
• Turned on default includeFontPadding . It is possible to turn off the includeFontPadding using TextStyle.platformTextStyle attribute. In the near future we will change the default behavior however until that time this allows us to better integrate line height improvements (aosp/2058653) and solve TextField clipping issues. ( I01423 , b/171394808 )

External Contribution

• MouseInjectionScope.scroll(delta = someDelta) is now inverted on Android if we scroll vertically (if someDelta is positive, it will scroll downward) ( Ifb697 , b/224992993 )

Version 1.2.0-alpha08

20 апреля 2022 г.

androidx.compose.ui:ui-*:1.2.0-alpha08 is released. Version 1.2.0-alpha08 contains these commits.

API Changes

• The pluralStringResource functions were marked as experimental in order to allow evolution to support better internationalization in the future. ( If24e4 )
• Paragraph and MultiParagraph are now accepting Constraints parameter. Passing Constraints.maxHeight is a no-op at the moment but will allow to do some calculation in the future, like ellipsizing based on the height. ( I6afee , b/168720622 )
• SubcomposeSlotReusePolicy.getSlotsToRetain() now accepts a custom MutableSet-like class which doesn't allow adding new items in it. ( Icd314 )
• PointerIcon is now a @Stable interface ( I9dafe )
• Partial consumption (down OR position) has been deprecated in PointerInputChange . You can use consume() to consume the change completely. You can use isConsumed to determine whether or not someone else has previously consumed the change.
• PointerInputChange::copy() now always makes a shallow copy. It means that copies of PointerInputChange will be consumed once one of the copies is consumed. If you want to create an unbound PointerInputChange , use constructor instead. ( Ie6be4 , b/225669674 )
• Enable Nested Scroll interop between Compose and View in the direction Compose > View. This means that a compose parent will be able to receive nested scroll deltas from a nested scroll view. ( If7949 , b/174348612 )
• New SemanticsProperty testTagsAsResourceId , which can be used to make Compose conform with UIAutomator tests designed for the View system. ( I39c20 )
• Display all available weights for systems fonts on Android when using FontFamily.SansSerif . This will use fallback font names like sans-serif-medium internally on API 21-28. This is a behavior change as previously only weights 400 and 700 were supported on API 21-28. ( I380fe , b/156048036 , b/226441992 )
• Paragraph and Multiparagraph instructors reordered positional arguments to before optional arguments. ( Idafaa )
• AndroidFont now takes typefaceLoader as a constructor parameter. ( I2c971 )

Version 1.2.0-alpha07

April 6, 2022

androidx.compose.ui:ui-*:1.2.0-alpha07 is released. Version 1.2.0-alpha07 contains these commits.

API Changes

• New function Snapshot.withoutReadObservation { ... } was added. It allows users to run the passed lambda without subscribing to the changes of the state values read during this block. You could find it useful in use cases when you want to benefit from the snapshot based thread safe write/reads, but want to be able to read the value without causing unnecessary recomposition or remeasure. ( I9f365 , b/214054486 )
• The consumeWindowInsets extension property of ComposeView allows developers to disable consumption of Android WindowInsets . This allows separate ComposeViews in the hierarchy to each apply WindowInsets without interfering with each other. ( I0ef08 , b/220943142 )
• Added KeyboardType.Decimal as an alternative to Keyboard.Number for specifically including decimal separator in IME. ( Iec4c8 , b/209835363 )
• PointerEventType.Scroll and PointerEvent.scrollDelta are stable APIs now ( I574c5 , b/225669674 )
• Enable Nested Scroll interop between View and Compose for cooperating View classes. This means compose is now able to dispatch scroll deltas to a (cooperating) View parent. ( I5d1ac , b/174348612 )
• Updated FontFamily.Resolver to integrate System-wide bold text accessibility setting ( I6c1e7 )
• Font(AssetManager, String, ...) is deprecated, replaced with Font(String, AssetManager, ...) . This is an experimental API. ( I1c7a4 )
• Add new font descriptor Font(DeviceFontFamilyName) to optionally lookup system-installed fonts during font fallback chains. ( I30468 , b/219754572 )
• Added temporary compatibility configuration for includeFontPadding in TextStyle/ParagraphStyle. includeFontPadding can be changed via TextStyle(platformStyle = PlatformTextStyle(includeFontPadding = true/false)) . This is a temporary configuration option to enable migration and will be removed. ( If47be , b/171394808 )
• Add GoogleFont.Provider.isAvailableOnDevice extension for debugging help. ( I64e31 )
• Add GoogleFont.Provider constructor for use with @ArrayRes ( Ic5ee1 , b/225984280 )
• Compose GoogleFont is now called Font(GoogleFont) , API remains stable otherwise. ( I125f2 )

Исправления ошибок

• Added lint check to material/Scaffold to ensure that the inner padding is being used ( Ifb111 )

Version 1.2.0-alpha06

23 марта 2022 г.

androidx.compose.ui:ui-*:1.2.0-alpha06 is released. Version 1.2.0-alpha06 contains these commits.

API Changes

• Added RequestFocus semantics action to request focus on the focusable target. ( I17b71 )
• Updated parsing of vector drawables to support auto mirroring to flip the content of a VectorPainter if the current layout direction is RTL. ( I79cd9 , b/185760237 )

• Updated shadow/ambient colors to be trailing parameters of Modifier.graphicsLayer for API compatibility ( I3f864 , b/160665122 )

• Added default implementations to shadow/ambient color on GraphicsLayerScope to ensure non-breaking API changes

• Added event time to RSB events ( Ief8ae )

• FocusOrder has now been merged into FocusProperties and focusProperties() now has all the capabilities of focusOrder() . FocusOrder and focusOrder() have been deprecated. focusOrder() that accepts a focusRequester should be replaced with a focusRequester() modifier in combination with focusProperties() . This allows the modifiers to have a stronger separation of concerns. ( I601b7 )

• Upgrading both RecyclerView and Compose will now result in much better scrolling performance for RecyclerViews with Compose views as children.

• Add ViewCompositionStrategy.Default as a means of retrieving the built-in default strategy

• Add ViewCompositionStrategy.DisposeOnDetachedFromWindowIfNotInPoolingContainer , which is the new default strategy and properly handles pooling containers such as RecyclerView. ( If7282 )

• Added support for annotating annotations classes with @Preview as a first step for adding the Multipreview feature.

Version 1.2.0-alpha04

February 23, 2022

androidx.compose.ui:ui-*:1.2.0-alpha04 is released. Version 1.2.0-alpha04 contains these commits.

API Changes

• Added ComposableTarget , ComposableTargetMarker and ComposableOpenTarget that allows compile time reporting of when a composable function is called targeting an applier it was not designed to use.

  In most cases the annotations can be inferred by the compose compiler plugin so using these annotation directly should be rare . The cases that cannot be inferred include creating and using a custom applier, abstract composable functions (such as interface methods), fields or global variables that are composable lambdas (local variables and parameters are inferred), or when using ComposeNode or a related composable functions .

  For custom appliers the composable functions that calls ComposeNode or ReusableComposeNode need to add a ComposableTarget annotation for the function and any composable lambda parameter types. It is recommended, however, to create an annotation that is annotated with ComposableTargetMarker and then the marked annotation be used instead of ComposableTarget directly. A composable annotation marked with ComposableTargetMarker is equivalent to a ComposbleTarget with the fully qualified name of the attribute class as the applier parameter. For an example of using ComposableTargetMarker see anroidx.compose.ui.UiComposable . ( I38f11 )

• Font(resId, ...) now takes loadingStrategy on stable API. ( Ief3d2 )

Version 1.2.0-alpha03

February 9, 2022

androidx.compose.ui:ui-*:1.2.0-alpha03 is released. Version 1.2.0-alpha03 contains these commits.

API Changes

• notifyFocusedRect methods in TextInputSession and TextInputService are now deprecated and won't be called. Use BringIntoViewRequester instead. ( Ia4302 , b/192043120 , b/216842427 , b/178211874 )
• Introduced destroyDisplayListData method on RenderNode stub class ( I1e659 , b/216660268 )
• Added a new api which allows to premeasure children of SubcomposeLayout you precomposed. ( I857ea )

• Added movableContentOf which converts a composable lambda into a lambda that moves it state, and corresponding nodes, to any new location it is called. When the previous call leaves the composition the state is temporarily preserved and if a new call to the lambda enters the composition then the state, and associated nodes, are moved to the location of the new call. If no new call is added the state is removed permanently and remember observers are notified.

  If a movableContentOf lambda is called multiple times in the same composition, new state and nodes are created for each call and, as calls leave the composition and new calls enter, the state is moved from the first leaving calls to the entering calls in the order they are called. All state not claimed by new calls is removed permanently. ( Ib4850 )

• FontFamilyResolver is now available via LocalFontFamilyResolver.current

• Added createFontFamilyResolver(context) and createFontFamilyResolver(context, coroutineScope) to create new FontFamily resolvers outside of compose usage.

• Paragraph and MultiParagraph now take FontFamily.Resolver

• Support for async and optional font loading, with fallback behavior. This path is used by Text and TextField, and exposed through FontFamilyResolver

• Support for preloading fonts via FontFamilyResolver.preload

• FontFamilyResolver.setAsyncLoadContext allows setting the global coroutine context used for loading async fonts. ( I87fe8 , b/174162090 )

• Added AndroidFont , a new low-level API for providing new types of font resource descriptors on Android. For example, loading fonts from an app-specific backend, optionally locating pre-installed fonts on-device, or loading a font from a resource not provided by the current Font factories.

• Expanded Font.ResourceLoaded API to support optional and async font loading. It is not recommended that application developers use this API directly. To add new types of fonts see AndroidFont .

• Font.AndroidResourceLoader extension function allows construction of a Font.ResourceLoader when outside of composition.

• Added loadingStrategy parameter to resource-based fonts, to allow async loading when resource font references downloadable fonts XML. ( Ie5aea , b/174162090 )

• Typeface(FontFamily) constructor is deprecated. This was previously used to preload fonts, which may take up to 10 seconds for downloadable fonts. With downloadable fonts, this call may block for 10 seconds. Instead use FontFamilyResolver.preload .

• fontResource(FontFamily): Typeface is deprecated. This was previously used to preload fonts, which may take up to 10 seconds for downloadable fonts. Instead use FontFamilyResolver.preload ( If8e7c , b/174162090 )

• SubcomposeLayoutState constructor accepting maxSlotsToRetainForReuse is now deprecated. Instead there is a new constructor accepting SubcomposeSlotReusePolicy - a new interface allowing more granular control on what slots should be retained for the future reuse. ( I52c4d )

• Exposes HSV and HSL function in Color as non-experimental API. The Oklab color space is now public API. ( I08fb6 , b/180731008 )

• Deprecated AndroidComposeTestRule.AndroidComposeStatement , which was not meant to be in public API and didn't do anything for you anyway. ( Ibc46b )

• Internal generated kt class rename ( Ia0b9e , b/174162090 )

• Removed FontLoadingStrategy.values ( I42a9d , b/174162090 )

• Desktop uses composition local for FontFamily.Resolver
• Desktop FontLoader is deprecated
• New createFontFamilyResolver factory on Desktop ( I6bbbb , b/174162090 )

Version 1.1.0

February 9, 2022

androidx.compose.ui:ui-*:1.1.0 is released. Version 1.1.0 contains these commits.

Important changes since 1.0.0

• Stable support for the Android 12 Overscroll effect
• Improvements to touch target sizing
  • Note that, with respect to Compose 1.0, Material components will expand their layout space to meet Material accessibility guidelines for touch target size . For instance, Button touch target will expand to a minimum size of 48x48dp, even if you set the Button's size to be smaller. This aligns Compose Material to the same behavior of Material Design Components, providing consistent behavior if you mix Views and Compose. This change also ensures that when you create your UI using Compose Material components, minimum requirements for touch target accessibility will be met.
• Stable Support for Navigation Rail
• Graduates a number of previously experimental APIs to stable
• Support for newer versions of Kotlin

• Add experimental Modifier.composed overloads that accept keys to compare for equality and qualify for skipping optimizations. ( Ice799 , b/205851704 )
• ComposeNotIdleException now extends from Exception instead of directly from Throwable . Note that this means that catch clauses that were catching Exception might now catch ComposeNotIdleException s, where they wouldn't do that previously. ( I9c217 )

Version 1.1.0-beta03

17 ноября 2021 г.

androidx.compose.ui:ui-*:1.1.0-beta03 is released. Version 1.1.0-beta03 contains these commits.

API Changes

• Added new modifier Modifier.onPlaced to allow placement change to be observed. Additional changes to child modifier's offset can therefore be made based on the observed placement change. ( I558fd )
• Removed InjectionScope.flush() and InjectionScope.dispose() . Flushing of all events and disposing of the scope now happens at the end of the called perform*Input() method like before. ( I2bed8 )
• Removed MultiModalInjectionScope.Touch and MultiModalInjectionScope.Mouse . In order to inject touch and mouse events for multi-modal gestures, you can now use MultiModalInjectionScope.touch() and MultiModalInjectionScope.mouse() , both of which accept a lambda that has the receiver scope of that modality. ( Idde18 )

Исправления ошибок

• The default value for durationMillis in TouchInjectionScope.swipeWithVelocity is now calculated such that the swipe is feasible. ( I19deb )

Version 1.1.0-alpha06

October 13, 2021

androidx.compose.ui:ui-*:1.1.0-alpha06 is released. Version 1.1.0-alpha06 contains these commits.

API Changes

• Remove ExperimentalComposeUiApi from ViewRootForInspector and LayoutInfo.ownerViewId ( I5c2e3 )
• A child-less overload for Layout was added, with improved efficiency ( Ib0d9a )
• Removed InternalCompilerApi from Composer methods that are required to be called cross-module ( I1aa0b )
• SemanticsNodeInteraction.performSemanticsAction now returns the SemanticsNodeInteraction on which the function was called. ( I9e5db )
• Added LocalInputModeManager CompositionLocal to detect TouchMode/NonTouchMode. ( I6a83c , b/175899786 )
• Added viewConfiguration: ViewConfiguration to LayoutInfo to allow consumers get the correct value for things like long press timeout. ( I76ca6 )
  • Added viewConfiguration: ViewConfiguration to InjectionScope to allow tests to adjust input injection based on things like long press timeout or touch slop.
  • Changed default duration of long press and double tap for both touch and mouse input to be based on the values in InjectionScope.viewConfiguration .
• Implementation of ExposedDropdownMenu based on ExposedDropdownMenuBox with TextField and DropdownMenu inside ( If60b2 )
• dismissOnOutsideClick was added to PopupProperties, replacing dismissOnClickOutside which was deprecated. The new property receives the click position and the anchor bounds, providing finer control over whether onDismissRequest should be invoked or not. For example, this can be useful to prevent anchor dismissal for touches on the anchor.
  • updateAndroidWindowManagerFlags was added to PopupProperties, offering low-level control over the flags passed by the popup to the Android WindowManager. The parameter of the lambda will be the flags calculated from the PopupProperties values that result in WindowManager flags: eg focusable. The result of the lambda will be the final flags which will be passed to the Android WindowManager. By default, updateAndroidWindowManagerFlags will leave the flags calculated from parameters unchanged. This API should be used with caution, only in cases where the popup has very specific behavior requirements. ( I6e9f9 )
• Recomposer.state has been deprecated and replaced by Recomposer.currentState to change its type to a StateFlow ( Ic2ab3 , b/197773820 )
• Added flush() and dispose() to InjectionScope . Use them when you want to flush all queued up events immediately and when you want to dispose of the scope, respectively. ( Ifb73a )
• Added performScrollToNode(matcher: SemanticsMatcher) that scrolls a scrollable container to the content that is matched by the given matcher. ( Ic1cb8 )
• InjectionScope now implements Density , allowing you to easily convert between px and dp in performTouchInput and friends. ( I8fe1f )

Исправления ошибок

• AndroidView now propagates LocalLifecycleOwner and LocalSavedStateRegistryOwner to its view via ViewTreeLifecycleOwner and ViewTreeSavedStateRegistryOwner. ( I38f96 , b/179708470 )
• Fix WearOS SwipeToDismissBox sometimes not handling swipes. ( I9387e )
• The default time between injected input events has been changed from 10ms to 16ms. This potentially changes the outcome of tests that perform input gestures, like a specific swipe. ( I829fd )

Version 1.1.0-alpha05

29 сентября 2021 г.

androidx.compose.ui:ui-*:1.1.0-alpha05 is released. Version 1.1.0-alpha05 contains these commits.

API Changes

• Added support for inter-modifier communication ( Id5467 , b/198826874 )
• Added experimental historical pointers to PointerEventChange. ( Ic1fd8 , b/197553056 , b/199921305 )
• Added density: Density and layoutDirection: LayoutDirection to LayoutInfo . This allows consumers of LayoutInfo to interpret the dimensions and position exposed in LayoutInfo properly. ( I002f1 )
• Added experimental support for injecting mouse events. Use performMouseInput to start sending mouse events, or send mouse events through the Mouse property of MultiModalInjectionScope during a multi modal input gesture with performMultiModalInput . See MouseInjectionScope for documentation of the available API. ( Iaa4a8 , b/190493367 )

Исправления ошибок

• Fixed accessibility support for scrollables (both lazy and non-lazy) with respect to scrolling ( I6cdb0 )
• Improved TouchInjectionScope.swipeWithVelocity . It now accepts a wider range of input variables and will suggest changes to the input if a swipe can't be created ( I40fbe , b/182477143 )

Version 1.1.0-alpha04

September 15, 2021

androidx.compose.ui:ui-*:1.1.0-alpha04 is released. Version 1.1.0-alpha04 contains these commits.

API Changes

• PointerEvent now has a PointerEventType to support hover events. ( I091fa )
• Allow children to accept pointer input outside of parent's pointer input bounds. Parents may intercept those calls with a property PointerInputScope.alwaysInterceptChildEvents ( I9eae3 , b/192479655 )
• Deprecated performGesture and GestureScope , which have been replaced by performTouchInput and TouchInjectionScope . ( Ia5f3f , b/190493367 )
• Added touchBoundsInRoot to SemanticsNode that includes the minimum touch target size so that developers can ensure that touch targets meet accessibility minimums. ( I2e14b , b/197751214 )
• Redo implementation of inspectable ( I927bc , b/191017532 )
• Changed parameter name of inspectable to match composed ( I3a482 , b/191017532 )

• Introduced performTouchInput and TouchInjectionScope as a replacement for performTouchInput and TouchInjectionScope , paving the way for other modalities (like mouse).

  TouchInjectionScope has the same methods as GestureScope , with the exception of movePointerTo and movePointerBy , which have been renamed to updatePointerTo and updatePointerBy . All other methods are the same.

  The behavior of TouchInjectionScope is almost identical to GestureScope , with two small details:

  1. When sending a down event while pointers had been moved without sending a move event (in other words, updatePointerTo() has been used, but not move() , and then down() is called), the previous implementation would advance the event time and send a move event before sending the down event. The new implementation still sends the move event, but doesn't advance the event time in this specific scenario.
  2. When sending an up event while pointers had been moved without sending a move event (similar as above), the previous implementation would advance the event time and send a move event before sending the up event. The new implementation does neither: the new positions of the pointers will only be reflected through the up event.

  Finally, TouchInjectionScope introduces a new method currentPosition(pointerId: Int) to get the current position of the given pointer. ( If1191 , b/190493367 )

Исправления ошибок

• Allow clip to extend touch target bounds beyond the clip region for minimum touch target purposes. ( I43e10 , b/171509422 )
• Support for stretch overscroll has been added on Android 12 devices. ( Iccf3c , b/171682480 )

Version 1.1.0-alpha03

September 1, 2021

androidx.compose.ui:ui-*:1.1.0-alpha03 is released. Version 1.1.0-alpha03 contains these commits.

Новые возможности

• Updated Compose 1.1.0-alpha03 to depend on Kotlin 1.5.30 . ( I74545 )

API Changes

• Added Modifier.inspectable for wrapping other modifiers. ( I1909b , b/191017532 )
• Added BlurredEdgeTreatment API to simplify blur use cases into more commonly used combinations of clip flags and TileModes. Most use cases involve either letting blurred content render outside the original content bounds and blurring regions outside these bounds with transparent black, or clipping content to content bounds sampling the closest edge for blur kernels that extend beyond content bounds. ( I6b4b7 , b/166927547 )
• Added support for RenderEffect in compose desktop. Introduced OffsetEffect as well as the blur modifier as a simple way to introduce blur visual effects to a portion of the composition hierarchy. ( I0f6aa , b/166927547 )
• Introduced RenderEffect API that can be optionally configured on a Modifier.graphicsLayer to alter the contents of the layer itself. This can be used to blur contents of a composable and child composables within a composition hierarchy. ( I47c4d , b/166927547 )
• AwaitPointerEventScope now has withTimeout() and withTimeoutOrNull() ( I507f0 , b/179239764 , b/182397793 )
• Added minimum touch target size to ViewConfiguration for use in semantics and pointer input to ensure accessibility. ( Ie861c )
• Add TileMode.Decal support which is useful in defining edge behavior for blur based RenderEffects. ( I7e8ed , b/166927547 )
• performScrollToIndex , performScrollToKey , hasScrollToIndexAction and hasScrollToKeyAction are now stable API ( I142ae , b/178483889 )
• Added test method to get the clipped bounds. ( I6b28e )

Исправления ошибок

• Removed isBounded method from BlurredEdgeTreatment in favor of explicitly checking if the shape parameter is null. ( I85d68 )

Version 1.1.0-alpha02

androidx.compose.ui:ui-*:1.1.0-alpha02 is released. Version 1.1.0-alpha02 contains these commits.

API Changes

• PointerEvent now has support for reading mouse button state and keyboard modifier state. ( I6310c , b/180075467 )
• Injected gestures now use the MainTestClock's time as the source of truth for time. The current time for injected events in performGesture will be initialized to the current time of the MainTestClock. ( Ifb364 , b/192064452 )
• Added DpRect(DpOffset, DpSize) constructor ( I2cf16 , b/194219828 )
• Added DpSize class ( I7abb1 , b/194219828 )

• RelocationRequester.bringIntoView now accepts a rectangle as a parameter which enables us to bring a part of a composable into view ( Ice2c5 , b/194330245 )
• AnimatedImageVector and the related APIs are now in the new androidx.compose.animation:animation-graphics module. ( I60873 )
• Added experimental modifier to handle relocation requests. ( I65a97 , b/178211874 )

• Introduced BrushPainter API to support drawing of an arbitrary Brush within a Painter, similar to ColorPainter

  Updated Brush API to have an intrinsic size parameter that is queried within BrushPainter ( Ia2752 , b/189466433 )

• Updated DrawScope#drawImage method that consumes source and destination rects to consume an optional FilterQuality parameter. This is useful for pixel art that is intended to be pixelated when scaled up for pixel based art. Updated BitmapPainter + Image composable to also consume an optional FilterQuality parameter ( Ie4fb0 , b/180311607 )

• Added GestureScope.advanceEventTime method to give more control over the timing of events in a gesture ( Ibf3e2 )

Исправления ошибок

• In order to better support chaining of draw modifiers, make sure the Modifier.paint implementation calls drawsContent. Previously Modifier.paint was expected to a leaf node in the chain of Modifiers, however, by doing so it prevents it from being configured on a composable container (ex. box) or adding additional decorations on top such as Modifier.paint().border() . By having Modifier.paint call drawContent after drawing the contents of the given painter, we have better behavior consistency in behavior with the modifier pattern. ( Ibb2a7 , b/178201337 , b/186213275 )
• Dialogs now follow the platform sizing behaviour. Set usePlatformDefaultWidth to false to override this behaviour. ( Iffaed , b/192682388 )
• Moved InfiniteAnimationPolicy to :compose:ui ( I5eb09 , b/160602714 )
• Scrolling via semantics actions for lazy lists and regular scrolling components is now animated ( Id9066 , b/190742024 )

Новые возможности

• Split ui-tooling module into ui-tooling and ui-tooling-preview ( Iefa28 , b/190649014 )

API Changes

• Removed deprecated experimental FocusManager#moveFocusIn and FocusManager#moveFocusOut ( I227d7 , b/170154986 , b/186567354 , b/168510304 )
• Canvas now supports a contentDescription parameter for accessibility. ( Ib547c )
• useDefaultMaxWidth in PopupProperties was renamed to usePlatformDefaultWidth . ( I05710 )
• Dialogs are now able to use the entire screen width. ( I83929 , b/190810877 )
• Added experimental support for HSV and HSL color representations. ( Id7cf8 , b/180731008 )

Behavior Changes

• Compose @Preview now provides a LocalActivityResultRegistryOwner that allows you to preview Composables that use APIs like rememberLauncherForActivityResult() that depend on that owner existing. ( Ib13d1 , b/185693006 )
• Compose @Preview now provides a LocalOnBackPressedDispatcherOwner that allows you to preview Composables that use APIs like BackHandler that depend on that owner existing. ( Ia1c05 , b/185693006 )

Исправления ошибок

• Moved InfiniteAnimationPolicy to androidx.compose.ui:ui ( I5eb09 , b/160602714 )
• AnimatedImageVector was temporarily removed in order to change the module structure. ( I41906 , b/160602714 )

Version 1.0.0-beta09

16 июня 2021 г.

androidx.compose.ui:ui-*:1.0.0-beta09 is released. Version 1.0.0-beta09 contains these commits.

API Changes

• Change enum Role and LiveRegionMode into inline classes with private constructor ( Id1890 )
• KeyboardCapitalization is converted into an inline class. ( Id5a1c )
• Change HapticFeedbackType to inline class. ( I255ec )
• Modifier.pointerInteropFilter is @ExperimentalComposeUiApi. ( Iede6c )
• TextAlign, FontSynthesis and TextDirection are now inline classes. ( I212fe )
• TextOverflow is changed to an inline class. ( I433af )
• FontStyle is now an inline class. ( I9e48b )

Исправления ошибок

• Key constants are @ExperimentalComposeUiApi for now. Consuming code can declare private constants prior to stabilization. ( Ia5d48 )
• Compose tests can now be run on Robolectric. The following limitations have so far been identified:
  • There is no native bitmap, so ImageBitmap() leads to a NullPointerException.
  • There is no drawing, so captureToImage() will indefinitely await the next draw pass (ie it deadlocks).
  • There is no font loaded, so any text will be measured incorrectly. All characters have a fixed height of around 20px and width of 1px.
  • ComposeTestRule.waitUntil {} does not run the main thread while it's waiting, making it effectively the same as ComposeTestRule.mainClock.advanceTimeUntil {} More limitations are expected to be identified in the future. ( I284fa )

Added Profile Rules

This release adds profile rules to the following compose modules ( I14ed6 ):

• androidx.compose.animation
• androidx.compose.animation-core
• androidx.compose.foundation
• androidx.compose.foundation-layout
• androidx.compose.material
• androidx.compose.material-ripple
• androidx.compose.runtime
• androidx.compose.ui
• androidx.compose.ui.geometry
• androidx.compose.ui.graphics
• androidx.compose.ui.text
• androidx.compose.ui.text
• androidx.compose.ui.unit
• androidx.compose.ui.util

What are profile rules?

• Profile rules for a library are specified in a text file baseline-prof.txt located in the src/main or equivalent directory. The file specifies a rule per line, where a rule in this case is a pattern for matching to methods or classes in the library. The syntax for these rules is a superset of the human-readable ART profile format that is used when using adb shell profman --dump-classes-and-methods ... . These rules take one of two forms to target either methods or classes.

• A method rule will have the following pattern:

  <FLAGS><CLASS_DESCRIPTOR>-><METHOD_SIGNATURE>
  

• And a class rule will have the following pattern:

  <CLASS_DESCRIPTOR>
  

• Here <FLAGS> is one or more of the characters H , S , and P to indicate whether or not this method should be flagged as "Hot", "Startup", or "Post Startup".

• The <CLASS_DESCRIPTOR> is the descriptor for the class that the targeted method belongs to. For example, the class androidx.compose.runtime.SlotTable would have a descriptor of Landroidx/compose/runtime/SlotTable; .

• The <METHOD_SIGNATURE> is the signature of the method, and includes the name, parameter types, and return types of the method. For example, the method fun isPlaced(): Boolean on LayoutNode has the signature isPlaced()Z .

• These patterns can have wildcards ( ** , * , and ? ) in order to have a single rule encompass multiple methods or classes.

What do the rules do?

• A method that has the flag H indicates that this method is a "hot" method, and should be compiled ahead of time.

• A method that has the flag S indicates that it is a method which is called at startup, and should be compiled ahead of time to avoid the cost of compilation and interpreting the method at startup time.

• A method that has the flag P indicates that it is a method which is called after startup.

• A class that is present in this file indicates that it is used during startup and should be pre-allocated in the heap to avoid the cost of class loading.

Как это работает?

• Libraries can define these rules which will be packaged in AAR artifacts. When an app is then built which includes these artifacts, these rules are merged together and the merged rules are used to build a compact binary ART profile that is specific to the app. ART can then leverage this profile when the app is installed on devices in order to ahead-of-time compile a specific subset of the application to improve the performance of the application, especially the first run. Note that this will have no effect on debuggable applications.

Исправления ошибок

• Fixed the bug introduced in beta07 where LazyColumn/Row items were displayed partially after the scroll ( I8c9ac , b/188566058 )
• Now detectDragGesures , detectVerticalGestures , and detectHorizontalGestures will consume the position change automatically, no need to call change.consumePositionChange in the onDrag callbacks ( I42fc4 , b/185096350 , b/187320697 )
• LayoutModifiers providing alignment lines was fixed. A bug causing the parent not being remeasured when the alignment lines of the children were changing was fixed. ( I4401f , b/174315652 )
• Modifier.onGloballyPositioned() was changed to report the coordinates of this modifier in the modifier chain, not the layout coordinates after applying all the modifiers. This means that now the ordering of modifiers is affecting what coordinates would be reported. ( Ieb67d , b/177926591 )

Version 1.0.0-beta07

18 мая 2021 г.

• KeyEventType enum is replaced by an inline class. ( Id670a , b/187055290 )
• FocusDirection enum is replaced by an inline class. ( Ib6d03 , b/187055290 , b/184086802 )
• Introduces ability to hoist the SubcomposeLayout state which allows you to precompose the content into a requires slotId which would make the next measure pass faster as once we try to subcompose with the given slotId next time there will be no composition needed. ( I42580 , b/184940225 )
• Added Clip Selection Handle ( Iff80d , b/183408447 )
• Removed unused APIs related to LayoutInspector support. ( I2ac78 )

Исправления ошибок

• LazyColumn/Row will now keep up to 2 previously visible items active (not disposed) even when they are scrolled out already. This allows the component to reuse the active subcompositions when we will need to compose a new item which improves the scrolling performance. ( Ie5555 )
• TextGeomerticTransform and TextDecoration on AnnotatedString will be applied as given. ( I61900 , b/184760917 )

• androidx.compose.ui:ui no longer depends on AppCompat or Fragment. If you are using a ComposeView in your application, and you are using Fragment and/or AppCompat, make sure that you are using AppCompat 1.3+ / Fragment 1.3+ - these versions are needed to correctly set lifecycle and saved state owners required for ComposeView. ( I1d6fa , b/161814404 )

This is the first release of Compose 1.0.0 Beta.

API Changes

• onStart callback has been added to detectDragGestures ( I67269 , b/179995594 )
• Modifiers for sizing to intrinsics are no longer experimental. ( I15744 )
• MeasureBlocks was renamed to MeasurePolicy which became a fun interface. Layout APIs were updated / simplified to use MeasurePolicy. ( Icab48 , b/167662468 , b/156751158 )
• InteractionState has been replaced with [Mutable]InteractionSource
  • Interfaces are responsible for emitting / collecting Interaction events.
  • Instead of passing interactionState = remember { InteractionState() } to components such as Button and Modifier.clickable() , use interactionSource = remember { MutableInteractionSource() } .
  • Instead of: Interaction.Pressed in interactionState you should instead use the extension functions on InteractionSource, such as InteractionSource.collectIsPressedAsState().
  • For complex use cases you can use InteractionSource.interactions to observe the stream of Interactions. See the InteractionSource documentation and samples for more information.
  • ( I85965 , b/152525426 , b/171913923 , b/171710801 , b/174852378 )
• Add AccessibilityMananger interface and LocalAccessibilityMananger in CompositionLocals ( I53520 )
• Removed deprecated LayoutCoordinates methods, use function instead of the property for positionInParent and boundsInParent ( I580ed , b/169874631 , b/175142755 )
• Typealiases replaced by underlying types:
  • ColorStop is now Pair<Float, Color>

  • ( I8dd1a )
• Created new TextInputSession for input sessions from low level text components such as CoreTextField. ( I8817f , b/177662148 )
• Placeable now exposes measuredSize, representing the size which the child layout actually measured to. This size might not respect the measurement constraints. ( Ib2729 , b/172560206 , b/172338608 )
• Add selectionGroup modifier that allows to mark collection of Tabs or RadioButtons for accessibility purposes ( Ie5c29 )

• The defaultFactory for compositionLocalOf and staticCompositionLocalOf is now required instead of optional.

  This changes removes a potential type error for non-nullable types where no default factory was provided. Previously this would provide a null reference for a non-nullable type.

  For nullable types consider supplying { null } as the default factory.

  We do not recommend using locals with non-nullable types unless a sensible default can be provided. If no sensible default exists, the defaultFactory lambda should throw an exception. However throwing an exception means that consumers of the local will have an implicit dependency on it being provided that is not enforced by the type system. ( Ifbd2a )

• Deprecated methods from ui modules were removed ( I646f6 )

• Size modifiers were renamed. Modifier.width/height/size were renamed to requiredWidth/requiredHeight/requiredSize. Modifier.preferredWidth/preferredHeight/preferredSize were renamed to width/height/size. ( I5b414 )

• Providers has been renamed to CompositionLocalProvider

  • The Composition constructor no longer accepts a key parameter, and has been deprecated.
  • currentCompositeKeyHash has been turned into a composable top level property instead of a composable top level function.
  • CompositionData and CompositionGroup have been moved to the androidx.compose.runtime.tooling namespace
  • ComposableLambda has been made an interface instead of a concrete class, and no longer has type parameters.
  • ComposableLambdaN has been made an interface instead of a concrete class, and no longer has type parameters.
  • The snapshotFlow function has been moved to the androidx.compose.runtime namespace
  • the merge method of SnapshotMutationPolicy is no longer experimental
  • The @TestOnly top level clearRoots function has been removed. It is no longer necessary.
  • keySourceInfoOf and resetSourceInfo functions have been removed. They are no longer necessary.
  • Composer.collectKeySourceInformation has been removed. It is no longer necessary.
  • isJoinedKey, joinedKeyLeft, and joinedKeyRight methods have been removed. They are no longer necessary.
  • Various top level APIs have been moved and reorganized into different files. Due to Kotlin's file class semantics, this will break binary compatibility but not source compatibility, so should not be an issue for most users.
  • ( I99b7d , b/177245490 )

• ComponentActivity.setContent() was removed from compose:ui. Use the one from androidx.activity:activity-compose:1.3.0-alpha01 . viewModel() and LocalViewModelStoreOwner were removed from compose:ui. Use the ones from androidx.lifecycle:lifecycle-viewmodel-compose:1.0.0-alpha01 ( I6f36b )

• SnapshotStateObserver is not Experimental anymore ( Id2e6a )

• Deleted some previously deprecated APIs ( Ice5da , b/178633932 )

• longPressGestureFilter and doubleClickGestureFilter have been removed. use Modifier.pointerInput with helper functions eg detectTapGestures ( I2fedf , b/175294473 )

• Removed String.format API refactored usages in various toString methods to not leverage String.format internally. ( Id1290 )

• Removed dp assertions ( I798d2 )

• Removed androidx.compose.runtime:runtime-dispatch ( I55feb )

  • Reordered parameters in ButtonDefaults.buttonColors() . Please note that because the type of the parameters have not changed, this will not cause an error in your code - please ensure you are either using named parameters or update the ordering manually, otherwise your code will not work the same as previously.
  • Added secondaryVariant parameter to darkColors() . This color is typically the same as secondary in dark theme, but adding for consistency and further customization.
  • Removed ElevationDefaults and animateElevation() from the public API surface since they were not commonly used / useful.
  • Renamed onValueChangeEnd in Slider to onValueChangeFinished and made it nullable.
  • Renamed text parameter in Snackbar to content for consistency.
  • Added contentPadding parameter to DropdownMenuItem to allow customizing the default padding and made content be an extension on RowScope .
  • Renamed ModalDrawerLayout to ModalDrawer .
  • Renamed BottomDrawerLayout to BottomDrawer .
  • ( I1cc66 )

• Allow nullable action in AccessibilityAction, change action label in AccessibilityAction and CustomAccessibilityAction from CharSequence to String ( I0dc82 )
• In order to better match naming conventions with ImageBitmap and ImageVector, ImagePainter has been renamed to BitmapPainter to parallel VectorPainter. ( Iba381 , b/174565889 )
• Better substring test APIs with substring now as an argument ( Icbe78 )
• Added an Modifier.focusOrder() that accepts a FocusRequester without specifying a custom focus order a lambda. This is useful when we only need to specify a reference but not a custom focus order for a composable ( I4f52a , b/179180978 )
• ComponentActivity.setContent has moved to androidx.activity.compose.setContent in the androidx.activity:activity-compose module. ( Icf416 )

• Added EditableText semantics to mark editable input text of the text field for accessibility and corresponding test methods to check the semantics ( I8e07a )
• Made OwnerLayer/OwnerScope/OwnerSnapshotObserver internal ( I4ffaf , b/175103944 )
• toIntPx() was renamed to roundToPx(). ( I9b7e4 , b/173502290 )

• Renamed Ambients to match the Ambient -> CompositionLocal rename. Ambients used to be named AmbientFoo, now CompositionLocals are named LocalFoo. ( I2d55d )
• The deprecated BaseTextField is now removed. Use BasicTextField instead. ( I71368 )
• Selection was moved to foundation. ( I7892b )
• Similarly to how we previously removed state { 0 } composable and now promote usage like remember { mutableStateOf(0) } we are going to remove savedInstanceState { 0 } composable. You should use rememberSaveable { mutableStateOf(0) } instead and it will save and restore automatically if the type used inside the MutableState can be stored in the Bundle. If previously you were passing a custom saver object now you need to use a new overload of rememberSaveable which has stateSaver parameter. The usage will look like this: val holder = rememberSaveable(stateSaver = HolderSaver) { mutableStateOf(Holder(0)) } ( Ib4c26 , b/177338004 )
• Added password semantics for accessibility ( I231ce )
• Added ProgressBarRangeInfo.Indeterminate to mark indeterminate progress bars for accessibility ( I6fe05 )

• Removed view.captureToImage() without any replacement. ( I7fcd2 )
• Introduced ColorMatrix API used to modify rgb values of source content Refactored ColorFilter API to be an interface and match the implementation of PathEffect. ( Ica1e8 )
• Add layoutDirection param to Shape's createOutline. This allows to create layout direction aware shapes. ( I57c20 , b/152756983 )
• onImeActionPerformed is deprecated. use KeyboardActions instead ( If0bbd , b/179071523 )
• Introduced an InfiniteAnimationPolicy coroutine context element that will be applied in infinite animations. By default no policy is installed, except when running tests with ComposeTestRule . ( I50ec4 , b/151940543 )
• canDrag has been removed from the Modifier.scrollable. ( Id66e7 , b/175294473 )
• Renamed LayoutCoordinates.parentCoordinates to LayoutCoordinates.parentLayoutCoordinates to allow for a new parentCoordinates property.

• Removed CoreText and CoreTextField from public API
  • Removed deprecated SelectionContainer overload
  • ( I99c19 )
• Tests in which Compose is used in hierarchies that are added/removed directly to the WindowManager are now more stable. ( Ie81ed , b/175765614 )
• Removed Recomposer.current(). [Abstract]ComposeView now default to lazily created, window-scoped Recomposers driven by the ViewTreeLifecycleOwner for the window. Recomposition and withFrameNanos-based animation ticks are paused while the host Lifecycle is stopped. ( I38e11 )
• Recomposer.runningRecomposers now offers a global StateFlow of read-only RecomposerInfo for observing ongoing composition state in the process. Prefer this API to Recomposer.current(), which is now deprecated. ( If8ebe )
• Saver, listSaver(), mapSaver(), autoSaver was moved from androidx.compose.runtime.savedinstancestate to androidx.compose.runtime.saveable ( I77fe6 )

• Parameters on RounderCornerShape, CutCornerShape and CornerBasedShape were renamed from left/right to start/end in order to support the shape's auto mirroring in the rtl direction. AbsoluteRounderCornerShape and AbsoluteCutCornerShape were introduced for the cases when auto-mirroring is not desired. ( I61040 , b/152756983 )

• The API the Compose compiler plugin targets has been refactored to use an interface instead of a concrete class. The interface also no longer uses a type parameter.

  This is an internal change that should not effect source code compatibility but is a binary breaking change. ( I3b922 , b/169406779 )

• Remove unintentionally public StringBuilder.deleteAt function ( Id6ed9 )

Исправления ошибок

• ComposeViews placed in view hierarchies that are children of another composition now host child compositions of their ancestors ( I92883 )
• Updated compose's imageFromResource API to reuse the resource drawable cache when loading ImageBitmap objects. ( If3627 , b/178751994 )

  • TextLayoutInput ( Iaff99 )
• Changed VisualTransformation to be a functional interface ( I3bba4 )
• Added a function reference parameter type ( I5e1bd )
• Add transformed bounds to InspectorNode ( Ice42f )

Исправления ошибок

• onCommit, onDispose, and onActive have been deprecated in favor of SideEffect and DisposableEffect APIs ( If760e )

• Changes to factory functions for Font/FontFamily/Typeface

  • Added factory functions that start with capital letter
  • Deprecated previous factory functions with lowercase first letters
  • New factory functions return the FontFamily instead of subclasses
  • Hid constructors of the subclasses, so that they can only be constructed via factory functions.
  • Renamed Font.asFontFamily to Font.toFontFamily ( I42aa7 )

• Introduced ComposeContentTestRule , which extends ComposeTestRule and defines setContent , which has been removed from ComposeTestRule . Added a factory method createEmptyComposeRule() that returns a ComposeTestRule and does not launch an Activity for you. Use this when you want to launch your Activity during your test, eg using ActivityScenario.launch ( I9d782 , b/174472899 )

• animateAsState is now animateFooAsState, where Foo is the type of the variable being animated. eg Float, Dp, Offset, etc ( Ie7e25 )

• Content description parameter has been added to the Image and Icon. It is used to provide description to the accessibility services ( I2ac4c )

• Remove displaySize as it should be avoided. Typically it is better to use size of onRoot() or window size at least. ( I62db4 )

• OnSizeChanged was reporting the size of the layout's contents. It now reports the size at its position within the modifier chain. ( I36b78 , b/177562900 )

• The emit() API and all overloads have been deprecated and renamed to ComposeNode. The APIs are identical, just a different name in order to follow the naming conventions of Compose ( I4137b )

• TextFieldValue accepts AnnotatedString. However this is an API only change and multi-style text editing is not implemented yet.

  • Removed initial from EditingBuffer constructor parameters. ( I326d5 )

• invalidate and compositionReference() are now deprecated in favor of currentRecomposeScope and rememberCompositionReference respectively. ( I583a8 )

• AnnotatedString is changed to extend from kotlin.CharSequence. Therefore length and subSequence are now instance functions, and extension functions are removed. ( Iaf429 )

• RememberObserver replaces CompositionLifecycleObserver and CompositionLifecycleObserver is now deprecated.

  RememberObserver is a replacement for CompositionLifecycleObserver with modified semantics and renamed methods. Changing to the new API can be done mechanically for objects that are only remembered once which is, and continues to be, the recommended practice. However, if a reference was remembered more than once in a composition onRemembered is called for each reference where onEnter is only called once. onEnter was called multiple time if the object was used in subcompositions, such as WithConstraints and Scaffold making the single onEnter call guarantee unreliable and it was removed for RememberObserver .

  RememberObserver adds onAbandoned which is called if the RememberObserver instance is returned from the callback passed to remember but was not remembered in the composition state and, therefore, will never have onRemembered called. This can occur if an exception terminates composition before completing or the composition is discarded because the state is was producing a composition for is no longer current or otherwise is no longer needed. If the instance of RememberObserver following the single reference recommendation above is tracking an external resource both onForgotten and onAbandoned each indicate that the resource is no longer needed. If the object is tracking work started or resources allocated in onRemembered , onAbandoned can be ignored as it will not be called if onRemembered is called. ( I02c36 )

• Deprecated arithmetic operations between 2 or more TextUnits. Deprecated TextUnit.Sp and TextUnit.Em functions in preference to the extension functions such as Int.sp and Int.em. ( I48369 )

• Resources in libraries with no explicitly declared public resources (ex. via public.xml) are now private by default. ( Ia1dcc , b/170882230 )

• ScrollableColumn/Row were deprecated. Using ScrollableColumn is less efficient compared to LazyColumn when you have a large scrolling content because with LazyColumn we can only compose/measure/draw visible elements. To prevent users from going the inefficient way we decided to deprecate ScrollableColumn and ScrollableRow and promote usages of LazyColumn and LazyRow instead. Users can still decide they don't need the lazy behaviour and use the modifiers directly like this: Column(Modifier.verticalScroll(rememberScrollState())) ( Ib976b , b/170468083 )

• New items(count: Int) factory method for scope of LazyColumn/LazyRow/LazyVerticalGrid. items(items: List) and itemsIndexed(items: List) are now extension functions so you have to manually import them when used. New extension overloads for Arrays: items(items: Array) and itemsIndexed(Array) ( I803fc , b/175562574 )

• Please use ImeAction.None instead of ImeAction.NoAction

  • Please use ImeAction.Default instead of ImeAction.Unspecified ( Ie1bcc )

• Leverage TestCoroutineDispatcher in testing ( I532b6 )

• Renamed TextInputService.onStateUpdated as updateState ( Id4853 )

• TransitionDefinition-based Transition has been deprecated ( I0ac57 )

• TextUnitType.Inherit is removed. Please use TextUnitType.Unspecified instead. ( I9ff64 )

Version 1.0.0-alpha10

January 13, 2021

androidx.compose.ui:ui-*:1.0.0-alpha10 is released. Version 1.0.0-alpha10 contains these commits.

Breaking Change

• Restructuring of the internal compiler API allows batching changes to the nodes generated as a result of composition into the "apply changes" phase of composition, after all @Composable functions have completed.

  This is a behavioral breaking change that might affect application code as nodes are no longer available from internal and experimental APIs until after changes have been applied. This can usually be worked around by surrounding code with such dependencies in a SideEffect composable to defer execution of the code until after the nodes have been created and initialized. ( I018da )

API Changes

• ImeOptions and KeyboardOptions are no more a data class ( I3c898 , b/168684531 )

• VisualTransformation API Changes

  • Renamed OffsetMap to OffsetMapping
  • Renamed OffsetMapping.identityOffsetMap to OffsetMapping.Identity
  • PasswordTransformation is no longer data-class
  • Moved OffsetMapping to its own file
  • ( I0bdf3 )

  • ( I820f2 , b/168014930 )

Version 1.0.0-alpha09

December 16, 2020

androidx.compose.ui:ui-*:1.0.0-alpha09 is released. Version 1.0.0-alpha09 contains these commits.

API Changes

• Deprecated KeyEvent.Alt is now removed. Use KeyEvent.isAltPressed instead. ( Idd695 )
• Modifier.keyInputFilter and Modifier.previewKeyInputFilter are deprecated use Modifier.onKeyEvent and Modifier.onPreviewKeyEvent instead ( Idbf1b , b/175156384 )
• Modifier.focusObserver is deprecated. Use Modifier.onFocusChanged or Modifier.onFocusEvent instead ( I30f17 , b/168511863 , b/168511484 )
• For suspending pointer input APIs, renamed HandlePointerInputScope to AwaitPointerEventScope and handlePointerInput() to awaitPointerEventScope(). ( Idf0a1 , b/175142755 )
• Autofill API is now experimental API and requires opt-in ( I0a1ec )
• Adding destructuring declarations to create FocuSRequester instances ( I35d84 , b/174817008 )

• Nested scroll system added. Refer to Modifier.nestedScroll for more details ( I36e15 , b/162408885 )
• subcomposeInto(LayoutNode) was made internal ( Id724a )

• The Applier interface has changed to simplify building trees bottom-up instead of top-down.

  The insert() method has been renamed to insertTopDown() .

  A new method, insertBottomUp() , was added.

  An applier either inserts nodes into the tree it is editing using insertTopDown() or insertBottomUp() depending on which performs better.

  Some trees, such as LayoutNode and View , are much more efficient to build bottom-up than top-down. Prior to this change, a stack of inserts was required to implement bottom-up which needed to be copied to every applier which needed bottom-up construction for performance. With this change an Applier overrides insertBottomUp() to build a tree bottom-up and insertTopDown() to build the tree top-down. ( Icbdc2 )

• Added dismissOnBackPress and dismissOnClickOutside properties to AndroidDialogProperties. These allow configuring when the dialog's onDismissRequest lambda will be invoked. ( If5e17 )

• Added painterResource API to handle opaquely loading Painter objects from either rasterized asset formats (like PNGs) or VectorDrawables. Consumers no longer have to determine the type of asset in advance and can call this method to get a Painter object to use in Image composables or painter modifiers. ( I2c703 , b/173818471 )

• Added Modifier.clearAndSetSemantics to clear descendants' semantics and set new ones. ( I277ca )

• Moved ContentDrawScope to ui-graphics module to be with DrawScope. ( Iee043 , b/173832789 )

• Introduced PathEffect graphics API to provide different patterns to stroked shapes. Deprecated usage of NativePathEffect in favor of expect/actual implementation of PathEffect. ( I5e976 , b/171072166 )

• Added IdlingResource interfaces to Compose, as a Compose supported variant of Espresso's idling resources. They can be registered and unregistered through the ComposeTestRule ( I433f3 )

• Removed global (un)registration of ComposeIdlingResource and global (un)registration of clocks into ComposeIdlingResource ( I32660 )

Исправления ошибок

• Lambdas in offset modifiers now return IntOffset rather than Float. ( Ic9ee5 , b/174137212 , b/174146755 )

• Removed SlotTable, SlotReader and SlotWriter from the public API. These were marked as InternalComposeAPI previously. Now they are internal to the compose module.

  CompositionData and CompositionGroup were added as a replacement for the ui-tooling API to use to extract composition information. These are public but are not intended for use outside the ui-tooling API as they provide the raw information the ui-tooling API interprets ( I31a9c )

• Refactored ShaderBrush to lazily create a shader instance when sizing information of the drawing environment is available. This is useful to define gradients that occupy the full drawing bounds of a composable at composition time, without having to implement custom DrawModifier implementations.

  Deprecated gradient function constructor APIs in favor of factory methods on a Gradient object. ( I511fc , b/173066799 )

• Deprecate LazyColumnFor, LazyRowFor, LazyColumnForIndexed and LazyRowForIndexed. Use LazyColumn and LazyRow instead ( I5b48c )

• Deprecated BuildCompat.isAtLeastR ( Idb37e )

• Added buildAnnotatedString factory function in order to build an AnnotatedString. Deprecated annotatedString builder function. ( Idfe0b )

• Removed extension methods on Float and Double to convert values to radians. Moved to be a private function within the implementation PathParser which was the only place where it was used ( I25f52 )

Version 1.0.0-alpha08

December 2, 2020

API Changes

• Add semantics action Dismiss ( I2b706 )
• Moved DrawModifier APIs from the androidx.compose.ui package to the androidx.compose.ui.draw package. Created DrawModifierDeprecated.kt file to include typealiases/helper methods to assist with the migration from the deprecated to the current APIs. ( Id6044 , b/173834241 )
• Renamed Modifier.drawLayer to Modifier.graphicsLayer Also updated related classes to GraphicsLayer as per API feedback. ( I0bd29 , b/173834241 )
• New methods placeable.placeWithLayer() and placeable.placeRelativeWithLayer() were added which allows custom layouts and layout modifiers to place a child with introducing a graphics layer for their drawing. Having that we can first optimize redrawings, so when we need to move a child we don't have to redraw its content, second we can apply draw transformations for a child ( Ibd8f6 , b/170296989 , b/171493718 , b/173030831 )
• <T> was removed from SubcomposeLayout declaration. You can use it without specifying a type now. ( Ib60c8 )

• Added WindowManager.isWindowFocused to check if the host window is in focus, and a WindowFocusObserver that provides an onWindowFocusChanged callback. ( I53b2a , b/170932874 )
• Updated TransformOrigin API to have destructuring syntax to return pivotFractionX and pivotFractionY as component1 and component2 ( If43c4 , b/173586560 )
• Added lint check for composable lambda parameter naming and position, to check for consistency with Compose guidelines. Also migrated some APIs using children as the name for their trailing lambda to content , according to the lint check and guidance. ( Iec48e )
• Added API to check if Alt, Ctrl, Meta or Shift modifier keys were pressed when a keyevent was dispatched. ( I50ed9 )
• Added a new Modifier.drawLayer() overload. It takes a lambda block on a new GraphicsLayerScope where you define the layer parameters in a way which allows to skip recomposition and relayout when the state change happens. DrawLayerModifier is now internal in preparation to migrating its logic into placeable.placeWithLayer() method of LayoutModifier ( I15e9f , b/173030831 )
• Deprecated Ambients named with Ambient as their suffix, and replaced them with new properties prefixed with Ambient, following other Ambients and Compose API guidelines. ( I33440 )
• Moved androidx.compose.ui.text.Typeface to androidx.compose.ui.text.font.Typeface ( Ic2b81 )
• Semantics argument mergeAllDescendants was renamed to mergeDescendants. ( Ib6250 )
• New drag gesture detector suspending pointer input API, including orientation locking. ( Icef25 )
• Renamed VectorAsset to ImageVector Moved and renamed VectorAsset to Builder to be an inner class of ImageVector as per API guidelines. Added typealias of VectorAssetBuilder to link to ImageVector.Builder for compat. ( Icfdc8 )
• Renamed ImageAsset and related methods to ImageBitmap. ( Ia2d99 )
• Add zIndex param for the PlacementScope's place() so Modifier.zIndex() now works as a LayoutModifier and any custom layout can set zIndexes for their children right in the placement block ( I711f7 , b/171493718 )

• Modifier.plus has been deprecated, use Modifier.then instead. 'Then' has a stronger signal of ordering, while also prohibits to type Modifier.padding().background() + anotherModifier , which breaks the chain and harder to read ( Iedd58 , b/161529964 )
• Add [Abstract]ComposeView View subclasses for hosting Compose content in a View hierarchy. ( I46357 )
• Row and Column are now inline function significantly reducing the overhead of using them. ( I75c10 )

• Added SemanticsNode.positionInRoot to get the position of a SemanticsNode relative to the root of the Compose hierarchy ( Icdf26 , b/161336532 )
• MotionEvents passed all the way through from Android, into Compose, and back into Android. ( I14be8 , b/158034713 )

• Modifier.tag was renamed to Modifier.layoutId, to avoid confusion with Modifier.testTag. ( I995f0 )

• Alignment line Int positions returned from Placeable#get(AlignmentLine) are now non-null. If the queried alignment line is missing, AlignmentLine.Unspecified will be returned. ( I896c5 , b/158134875 )

• The AndroidView composable was added a modifier parameter. ( I48a88 , b/158746303 )

• Semantics() is deprecated. Use Modifier.semantics() instead. ( I72407 , b/158841414 )

• Add viewModel() composable which allows to create or get already created ViewModel similarly to how it works in Activity or Fragment ( I5fdd1 )

• Replaced usage of IntPx with Int. Replaced IntPxPosition with IntOffset. Replaced IntPxSize with IntSize. ( Ib7b44 )

• In order to consolidate the number of classes used to represent sizing information, standardize on usage of the Size class instead of PxSize. This provides the benefits of an inline class to leverage a long to pack 2 float values to represent width and height represented as floats. ( Ic0191 )

• In order to consolidate the number of classes used to represent positioning information, standardize on usage of the Offset class instead of PxPosition. This provides the benefits of an inline class to leverage a long to pack 2 float values to represent x and y offsets represented as floats. ( I3ad98 )

• Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters. Deleted Px class in its entirety ( I3ff33 )

• Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters ( I086f4 )

• Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters ( Id3434 )

• Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters ( I97a5a )

• TestTag is now deprecated. Use Modifier.testTag instead. ( If5110 , b/157173105 )

• Modifier.semantics has been undeprecated to allow usages for high level components. ( I4cfdc )

• Consolidated CanvasScope implementations so there is now just DrawScope and ContentDrawScope Renamed CanvasScope to DrawScope. Updated DrawScope to implement Density interface and provide LayoutDirection Deleted DrawScope subclass in ContentDrawScope Painter and PainterModifier have been updated to no longer maintain an RTL property themselves as DrawScope provides this already without manually providing it ( I1798e )

• DoubleTapGestureFilter now disambiguates SingleTapGestureFilter across the tree. ( If92b1 )

• Updated Alignment API and added support for absolute alignment (which does not auto-mirror in Rtl context) ( I38cd3 )

• DrawLayer modifiers api has been changed: outlineShape renamed to shape and has the RectangleShape default value and now non-nullable; clipToOutline renamed to clip; clipToBounds removed as it is the same as clip == true with RectangleShape ( I7ef11 , b/155075735 )

• Updated higher level compose APIs that expose a Canvas to expose CanvasScope instead. This removes the need for consumers to maintain their own Paint objects. For consumers that still require access to a Canvas they can use the drawCanvas extension method which provides a callback to issue drawing commands with the underlying Canvas. ( I80afd )

• WithConstraints trailing lambda API has been changed. Now instead of two params it has a receiver scope which in addition to constraints and layoutDirection provides minWidth, maxWidth, minHeight and maxHeight properties in Dp ( I91b9a , b/149979702 )

• Renamed LayoutModifier2 to LayoutModifier. ( Id29f3 )

• Removed deprecated LayoutModifier interface. ( I2a9d6 )

• Intrinsic measurements functions in Layout and LayoutModifier2 have an IntrinsicMeasureScope receiver now which provides intrinsics query API with implicitly propagated layout direction. ( Id9945 )

• Layout and LayoutModifier children can be measured with a different layout direction. ( Ibd731 )

• New Modifier.zIndex() is added to control the drawing order of the children within the same parent layout. elevation property on DrawLayerModifier is renamed to shadowElevation and doesn't control the drawing order anymore. The params order fo DrawShadow is changed: elevation is now the first one and the shape is the second one with a RectangleShape default. ( I20150 , b/152417501 )

• Removed onSizeChange and onPositionChange in Owner. ( I5c718 )

• Added Constraints2, a copy of Constraints that does only supports Int connstraints values rather than IntPx. IntPx will be removed and all integer constraints will be assumed to be pixels like Android.

  • Added IntSize as well, which will eventually replace IntPxSize. ( I4b43a )

• Made Alignment instantiable with arbitrary values. Added 1D Alignments. ( Ia0c05 )

• alignToSiblings now accepts a Measured instead of Placeable. ( I5788d )

• ( I45f09 , b/152842521 )

  • Renamed ScaleFit to ContentScale
  • Moved ContentScale from ui-graphics to ui-core module to live in the same module as the Alignment API.
  • Renamed FillMaxDimension to Crop
  • Renamed FillMinDimension to Fit
  • Renamed Fit to Inside to better match
  • ImageView.ScaleType equivalents
  • Added documentation indicating that the combination of Crop and Alignment.Center achieves the same result as ImageView.ScaleType.CENTER_CROP and Fit used with Alignment.Center achieves the same result as ImageView.ScaleType.FIT_CENTER Inside used with Alignment.Center achieves the same result as ImageView.ScaleType.CENTER_INSIDE

• Rtl support for draw modifiers. ( I0aaf9 )

• Released API for inflating Android Views from XML. See ViewInCompose demo for more details. ( I42916 )

• Improve DrawModifier API:

  • Made the receiver scope for draw() ContentDrawScope
  • Removed all parameters on draw()
  • DrawScope has same interface as former CanvasScope
  • ContentDrawScope has drawContent() method ( Ibaced , b/152919067 )

• Added positionInParent and boundsInParent for LayoutCoordinates. ( Icacdd , b/152735784 )

• DrawLayerModifier and drawLayer() now default clipToBounds and clipToOutline to false. ( I0eb8b , b/152810850 )

• Renamed LayoutResult to MeasureResult. ( Id8c68 )

• Added LayoutModifier2, a new API for defining layout modifiers; deprecated LayoutModifier ( If32ac )

• Replaced Modifier plus operator with factory extension functions ( I225e4 )

• Added translationX/Y properties to support offseting the display list of drawing commands for a given Layer. This is useful to move content in response to animations or touch events. ( I8641c )

• Added pivotX, pivotY parameters to Layer APIs to support rotation and scaling around a particular point on a layer ( Icf7c3 )

• Add OnPositionedModifier and OnChildPositionedModifier to replace OnPositioned and OnChildPositioned composable functions. ( I2ec8f )

• Added LayerModifier, a modifier that allows adding a RenderNode for a Layout. It allows setting clipping, opacity, rotation, scaling, and shadows. This will replace RepaintBoundary. ( I7100d , b/150774014 )

• Made the layout direction be propagated from parent layout node to children. Added layout direction modifier. ( I3d955 )

• Stack component supports right-to-left directionality ( Ic9e00 )

• Initial support for Rtl in Compose layout ( Ia5519 )

• Density and DensityScope were merged into one interface. Instead of ambientDensity() you can now use DensityAmbient.current. Instead of withDensity(density) just with(density) ( I11cb1 )

• Changed LayoutCoordinates to make providedAlignmentLines a Set instead of a Map and have LayoutCoordinates implement the get() operator instead for retrieving a value. This makes it easier for modifiers to modify one or more value of the set without creating a new collection for each modifier. ( I0245a )

• LayoutCoordinates no longer has a position property. The position property does not make sense when considering LayoutModifiers, rotation, or scaling. Instead, developers should use parentCoordinates and childToLocal() to calculate the transform from one LayoutCoordinate to another.

  LayoutCoordinates uses IntPxSize for the size property instead of PxSize. Layouts use integer pixel sizes for layouts, so all layout sizes should use integers and not floating point values. ( I9367b )

• Improvements to the API surface of Constraints ( I0fd15 )

• Created CanvasScope API that wraps a Canvas object to expose a stateless, declarative drawing API surface. Transformations are contained within their own receiver scope and sizing information is also scoped to corresponding inset bounds. It does not require a consumer to maintain its own Paint state object for configuring drawing operations.

  • Added CanvasScopeSample as well as updated the demo app to include a declarative graphics demo ( Ifd86d )

• Removed unused MaskFilter API as it has limited usage and is not optimized for hardware acceleration in most use cases ( I54f76 )

• RectangleShape moved from androidx.ui.foundation.shape.* to androidx.ui.graphics.* ( Ia74d5 , b/154507984 )

• Replaced all nullable Color uses in API with non-nullable and use Color.Unset instead of null ( Iabaa7 )

• Introduce additional optional rect parameter to ImagePainter to support drawing a subsection of underlying ImageAsset ( I0ea9e )

• Added Unset Color to represent an unset value without boxing Colors. ( If901a )

• Added Canvas.rotate and Canvas.scale extension methods to consume optional pivot coordinates for transformations. These default to the top left corner of the current canvas translation.

  Also moved Canvas.rotateRad to be an extension method for consistency ( Ibaca6 )

• Created PixelMap API to support querying pixel information from an ImageAsset. ( I69ad6 )

• Renamed toFrameworkRect/toFrameworkRectF to toAndroidRect/toAndroidRectF to match naming convention for object conversions between compose and the Android framework APIs they are built on top of. Also updated docs on these APIs ( I86337 )

• Added VectorPainter API to replace existing subcomposition API for vector graphics. Result of subcomposition is a VectorPainter object instead of a DrawModifier. Deprecated previous DrawVector composables in favor of VectorPainter.

  Renamed Image(Painter) API to PaintBox(Painter) Created Vector composable that behaves like the Image composable except with a VectorAsset instead of an ImageAsset ( I9af9a , b/149030271 )

• Renamed Image to ImageAsset to better differentiate the difference between the Image data and the upcoming Image composable used to participate in layout and draw content. _Body:Created extension method on android.graphics.Bitmap, Bitmap.asImageAsset(), to create an instance of an ImageAsset useful for combining traditional Android application development with the compose framework ( Id5bbd )

• Added TextDirection.Content ( I48f36 )

• Added TextDecoration.plus operator ( I0ad1a )

• Force is removed from TextDirectionAlgorithm enum values ( Icc944 )

• TextDirectionAlgorithm is renamed as TextDirection ( I75ce8 )

• Implements LongPressAndDrag for TextField Selection. ( I17919 )

• Changed the package name for Locale and LocaleList from androidx.ui.text to androidx.ui.intl ( I8132c )

• TextField's cursor has a blinking animation ( Id10a7 )

• API change: AnnotatedString(builder: Builder) is renamed to annotatedString(builder: Builder). ( Ia6377 )

• API change: AnnotatedString.Item is renamed to AnnotatedString.Range. ( I2d44d )

• Rename AnnotatedString.Builder.addAnnotationString to addStringAnnotation. ( I5059e )

• Now it is possible to hide/show software keyboard by using SoftwareKeyboardController which is delivered by onTextInputStarted callback ( I8dc44 , b/151860051 )

• Added plus operator for (Text/Paragraph/Span)Style which delegates to merge() function. ( Ia1add )

• FontWeight.lerp does not snap anymore. It is still a data class. ( I521c2 )

• FontWeight constructor is now public, it is not data class anymore. ( Id6b1f )

• Add getLineStart, getLineEnd, getEllipsisOffset and getEllipsisCount to TextLayoutResult ( Ibc801 )

• ui-text module is renamed as ui-text-core ( I57dec )

• Removed unused Size class as there is a duplicate Size class in the ui-geometry module that is being consumed. ( I1b602 )

• Added AdapterList, a scrolling list component that only composes and lays out the visible items. Currently known issues include that it is vertical-only and does not fully handle all cases of changes to its children. ( Ib351b )

• Add paddings, border, shape and background param to Box ( I05027 , b/148147281 )

Исправления ошибок

• onFocusChange callback in text fields renamed to onFocusChanged ( Ida4a1 )
• VerticalScroller and HoriziontalScroller have been deprecated. Use ScrollableColumn and ScrollableRow for build-in experience with Column/Row behaviour and parameters, or Modifier.verticalScroll and Modifier.horizontalScroll on your own element. Similarly, ScrollerPosition has been deprecated in favor of ScrollState' ( I400ce , b/157225838 , b/149460415 , b/154105299 )
• runOnIdleCompose renamed to runOnIdle ( I83607 )
• Several testing APIs were renamed to be more intuitive. All findXYZ APIs were renamed to onNodeXYZ. All doXYZ APIs were renamed to performXYZ. ( I7f164 )
• Compose UI can now be composed inside ViewGroups without requiring a new composition. See ViewInteropDemo for an example. ( I9ab0b , b/160455080 )
• Added sortWith and removeRange to MutableVector ( Icccf7 )
• Implement Drag Selection Handles to change selection for TextField. ( I27032 )
• Removed Shader inline class that wrapped the NativeShader expect class Renamed NativeShader to Shader. The wrapped Shader inline class did not add anything valuable to the API surface and was an inline class, so use the NativeShader class directly. ( I25e4d )

• Refactored PainterModifier to no longer provide scaling based on the given constraints and ContentScale parameter. Implementations of Painter are to scale their drawing content themselves based on the given size of the DrawScope they are drawing into.

  Fixed issue where VectorPainter's cache bitmap was sized to its default size instead of the given size to draw into.

  Updated ImagePainter to scale its content instead of relying on PainterModifier to do so on its behalf. ( I6ba90 )

• add top-level withFrameNanos function for animation timing ( Ie34c5 )

• @Untracked annotation has been deprecated. Replace with @ComposableContract(tracked=false) ( Id211e )

• androidx.ui.foundation.TextFieldValue and androidx.ui.input.EditorValue is deprecated. TextField, FilledTextField and CoreTextField composables that uses that type is also deprecated. Please use androidx.ui.input.TextFieldValue instead ( I4066d , b/155211005 )

• Fixed issue where pointer input dispatch would cause a crash if PointerInputFilters were removed via subcomposition during disptach. This is now fixed. ( I1f48b , b/157998762 )

• Fixed issue where pointer input dispatch would cause a crash if PointerInputFilters were removed via subcomposition during disptach. This is now fixed. ( Iab398 , b/157998762 )

• Refactored Radius class to be an inline class. Removed companion creation methods in favor of function constructor with default parameter to have the radius along the y-axis match that of the mandatory x-axis radius parameter.

  Updated DrawScope.drawRoundRect to consume a single Radius parameter instead of 2 separate float values for the radius along the x and y axis ( I46d1b )

• The Recompose composable is no longer a useful abstraction. Most recomposition should happen as a result of MutableState assignments. For anything beyond that, it is recommended that you use the invalidate function to trigger a recomposition of the current scope. ( Ifc992 )

• Replaced usage of Px class in various compose classes as part of the large refactoring effort to only rely on Dp and primitive types for pixel parameters ( Iede0b )

• Changes the code generation strategy of Compose's compiler. Prior to the change, the compose compiler would transform calls to composable functions. With this change, we now transform the body of a composable function and leave the callsite unaltered (mostly).

  This means that most of the logic communicating with the compose runtime happens at the start of the function body, instead of at the callsite.

  This should be a source-compatible change for all usage of compose. Most users of compose should not have to update any code as a result of this change.

  In order to support this work, the JVM signature of all composable functions has changed. A Composable function accepting a single parameter is transformed into a function accepting 3 parameters, the additional parameters are the Composer, a 'key' integer. a bitmask integer used to propagate metadata through calls.

  Compose now also transforms default arguments to a composable function. It does this without introducing an additional synthetic default overload of the function itself, so this change will result in fewer functions being defined.

  Known intentional behavioral changes resulting from this:

  1. Some calls will skip where they wouldn't have previously
  2. Composable expressions in default argument expressions are now correctly subscribed to and handled

  This work included some optimizations: 1. The result of comparisons of parameters are propagated through the call graph to other composable functions. This will result in fewer comparisons at runtime, reduces the slot table size, as well as more skipping of composable functions that were previously not skipped 2. Paremeters which are determined to be “static” at compile time are no longer compared or stored in the runtime. This reduces the number of comparisons and reduces slot table size. 3. Control flow structure of the body of functions is used to minimize the number of groups that are generated. This reduces slot table size and results in less work for the runtime 4. Unused dispatch and receiver parameters to functions are not included in determining skippability of the function if they are not used inside of the body of the function.

  Most breaking changes were for APIs that the compiler targets directly, and typical use of compose will not be affected: 1. Composer::startExpr was removed 2. Composer::endExpr was removed 3. Composer::call was deprecated 4. The non-varargs overloads of key have been removed. Use the vararg version going forward. 5. The Pivotal annotation was deprecated. Use key as a replacement. 6. ScopeUpdateScope::updateScope was changed to expect a Function3 instead of Function1 7. restartableFunction and restartableFunctionN were updated to include additional compile time parameters ( I60756 , b/143464846 )

• Removed deprecated LayoutAlign modifiers. ( I10877 )

• Removed RepaintBoundary in favor of DrawLayerModifier ( I00aa4 )

• Button, FloatingActionButton and Clickable now have a separate enabled param. Some of the params on Button were renamed or reordered. ( I54b5a )

• Replaced ButtonStyle with distinct functions and removed text (string) overload. See updated samples for usage information. ( If63ab , b/146478620 , b/146482131 )

• Breaking changes to the ambients API. See log and Ambient<T> documentation for details ( I4c7ee , b/143769776 )

• Changed the behavior of default TextDirection to be determined by LayoutDirection. ie If LayoutDirection is RTL, default TextDirection will be RTL. Previously it was TextDirection.ContentOrLtr/Rtl ( I4e803 )

• Bug fix: When font weight and font style are nested on an AnnotatedString, text is not rendered correctly. ( I77a9d )

• Adds commonly used parameters to Text(). If you are currently creating a local text style to pass a small number of these parameters, such as Text(style = TextStyle(textAlign = TextAlign.Center)), you can now just provide the parameters directly: Text(textAlign = TextAlign.Center) ( I82768 )

• ui-android-text module is renamed as ui-text-android ( I68cbe )
