為以 Android View 為基礎的應用程式開發 UI
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
試試 Compose 方式
建議使用 Jetpack XR SDK 的 Jetpack Compose 做為 Android XR 的 UI 工具包。
使用 Android Jetpack Compose 架構,是充分運用 Android UI 開發最新進展的最佳方式,並確保應用程式符合業界最佳做法。
不過,如果您尚未遷移,且正在處理 Android View 應用程式的空間化作業,可以採取幾種方法。
在 SpatialPanels 中重複使用現有的 Views
SpatialPanel
s 屬於 Jetpack Compose for XR 程式庫,但也會接受 Views。在 MainActivity 中使用 Subspace
時,請將現有檢視區塊放入 SpatialPanel
,如以下範例所示。
setContent {
Subspace {
SpatialPanel(
modifier = SubspaceModifier.height(500.dp).width(500.dp).depth(25.dp)
) { MyCustomView(this@ActivityWithSubspaceContent) }
}
}
使用 Android View 和 Compose 互通性 API
請參閱有關 Views 和 Compose 互通性的指南。這份文件說明如何一併使用這些架構,並提供可用的程式碼範例連結。
使用 ComposeView 將空間面板和軌跡球新增至現有片段
在 XML 版面配置中使用 ComposeView
新增可組合函式,並建立新的 XR 內容。使用檢視繫結或 findViewById
,在 onCreateView()
函式中找出 ComposeView
。
進一步瞭解ComposeView
指引。
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View {
val view = inflater.inflate(R.layout.example_fragment, container, false)
view.findViewById<ComposeView>(R.id.compose_view).apply {
// Dispose of the Composition when the view's LifecycleOwner
// is destroyed
setViewCompositionStrategy(ViewCompositionStrategy.DisposeOnViewTreeLifecycleDestroyed)
setContent {
// In Compose world
SpatialPanel(SubspaceModifier.height(500.dp).width(500.dp)) {
Text("Spatial Panel with Orbiter")
}
}
}
return view
}
直接使用 Jetpack SceneCore 程式庫
Compose for XR 是以 Jetpack SceneCore 為基礎建構而成,如果您要將以 Views 為基礎的應用程式空間化,可以繼續在 Compose for XR 中使用現有的 UI 程式碼,也可以選擇直接使用 Jetpack SceneCore 的 Session
。
您可以使用 PanelEntity
直接從 SceneCore 建構面板。使用 dimensions
以公尺為單位設定面板大小,或使用 pixelDimensions
以像素為單位設定面板大小。您可以使用對應的元件,選擇製作可移動或可調整大小的面板。詳情請參閱「為實體新增常見行為」。
val panelContent = MyCustomView(this)
val panelEntity = PanelEntity.create(
session = xrSession,
view = panelContent,
pixelDimensions = IntSize2d(500, 500),
name = "panel entity"
)

When using [`Subspace`](/reference/kotlin/androidx/xr/compose/spatial/package-summary#Subspace(kotlin.Function1)) in your MainActivity,\nplace an existing view into a [`SpatialPanel`](/reference/kotlin/androidx/xr/compose/subspace/package-summary#SpatialPanel(androidx.xr.compose.subspace.layout.SubspaceModifier,androidx.xr.compose.subspace.layout.SpatialShape,kotlin.Function0)) as shown in the following\nexample.\n\n\n```kotlin\nsetContent {\n Subspace {\n SpatialPanel(\n modifier = SubspaceModifier.height(500.dp).width(500.dp).depth(25.dp)\n ) { MyCustomView(this@ActivityWithSubspaceContent) }\n }\n}https://github.com/android/snippets/blob/7a0ebbee11495f628cf9d574f6b6069c2867232a/xr/src/main/java/com/example/xr/compose/Views.kt#L48-L54\n```\n\n\u003cbr /\u003e\n\nUse Android Views and Compose interoperability APIs\n\nConsult [guidance on interoperability between Views and Compose](/develop/ui/compose/migrate/interoperability-apis).

If you are\nspatializing a Views based app, you may continue to use your existing UI code\nwithin Compose for XR or choose to work directly with Jetpack SceneCore's\n[`Session`](/reference/kotlin/androidx/xr/runtime/Session) instead.\n\nYou can build panels directly from SceneCore using [`PanelEntity`](/reference/kotlin/androidx/xr/scenecore/PanelEntity). Set the\nsize of the panel in meters using [`dimensions`](/reference/kotlin/androidx/xr/scenecore/PanelEntity#create(androidx.xr.runtime.Session,android.view.View,androidx.xr.runtime.math.FloatSize2d,kotlin.String,androidx.xr.runtime.math.Pose)), or in pixels using\n[`pixelDimensions`](/reference/kotlin/androidx/xr/scenecore/PanelEntity#create(androidx.xr.runtime.Session,android.view.View,androidx.xr.runtime.math.IntSize2d,kotlin.String,androidx.xr.runtime.math.Pose)).
