AccessibilityWindowInfo

TYPE_ACCESSIBILITY_OVERLAY

public static final int TYPE_ACCESSIBILITY_OVERLAY

Window type: Windows that are overlaid only by an AccessibilityService for interception of user interactions without changing the windows an accessibility service can introspect. In particular, an accessibility service can introspect only windows that a sighted user can interact with which they can touch these windows or can type into these windows. For example, if there is a full screen accessibility overlay that is touchable, the windows below it will be introspectable by an accessibility service regardless they are covered by a touchable window.

Constant Value: 4 (0x00000004)

TYPE_APPLICATION

public static final int TYPE_APPLICATION

Window type: This is an application window. Such a window shows UI for interacting with an application.

Constant Value: 1 (0x00000001)

TYPE_INPUT_METHOD

public static final int TYPE_INPUT_METHOD

Window type: This is an input method window. Such a window shows UI for inputting text such as keyboard, suggestions, etc.

Constant Value: 2 (0x00000002)

TYPE_MAGNIFICATION_OVERLAY

public static final int TYPE_MAGNIFICATION_OVERLAY

Window type: A system window used to show the UI for the interaction with window-based magnification, which includes the magnified content and the option menu.

Constant Value: 6 (0x00000006)

TYPE_SPLIT_SCREEN_DIVIDER

public static final int TYPE_SPLIT_SCREEN_DIVIDER

Window type: A system window used to divide the screen in split-screen mode. This type of window is present only in split-screen mode.

Constant Value: 5 (0x00000005)

TYPE_SYSTEM

public static final int TYPE_SYSTEM

Window type: This is a system window. Such a window shows UI for interacting with the system.

Constant Value: 3 (0x00000003)

CREATOR

public static final Creator<AccessibilityWindowInfo> CREATOR

AccessibilityWindowInfo

public AccessibilityWindowInfo ()

Creates a new AccessibilityWindowInfo.

AccessibilityWindowInfo

public AccessibilityWindowInfo (AccessibilityWindowInfo info)

Copy constructor. Creates a new AccessibilityWindowInfo, and this new instance is initialized from given info.

describeContents

public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

equals

public boolean equals (Object obj)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

• It is reflexive: for any non-null reference value x, x.equals(x) should return true.
• It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
• It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
• For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

getAnchor

public AccessibilityNodeInfo getAnchor ()

Gets the node that anchors this window to another.

getBoundsInScreen

public void getBoundsInScreen (Rect outBounds)

Gets the bounds of this window in the screen. This is equivalent to get the bounds of the Region from getRegionInScreen(android.graphics.Region).

getChild

public AccessibilityWindowInfo getChild (int index)

Gets the child window at a given index.

getChildCount

public int getChildCount ()

Gets the number of child windows.

getDisplayId

public int getDisplayId ()

Returns the ID of the display this window is on, for use with DisplayManager.getDisplay(int).

getId

public int getId ()

Gets the unique window id.

getLayer

public int getLayer ()

Gets the layer which determines the Z-order of the window. Windows with greater layer appear on top of windows with lesser layer.

getLocales

public LocaleList getLocales ()

Return the LocaleList of the window.

getParent

public AccessibilityWindowInfo getParent ()

Gets the parent window.

getRegionInScreen

public void getRegionInScreen (Region outRegion)

Gets the touchable region of this window in the screen.

getRoot

public AccessibilityNodeInfo getRoot (int prefetchingStrategy)

Gets the root node in the window's hierarchy.

getRoot

public AccessibilityNodeInfo getRoot ()

Gets the root node in the window's hierarchy.

getTitle

public CharSequence getTitle ()

Gets the title of the window.

getTransitionTimeMillis

public long getTransitionTimeMillis ()

Return the SystemClock.uptimeMillis() at which the last transition happens. A transition happens when getBoundsInScreen(android.graphics.Rect) is changed.
Value is a non-negative timestamp in the SystemClock.uptimeMillis() time base.

getType

public int getType ()

Gets the type of the window.

hashCode

public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

isAccessibilityFocused

public boolean isAccessibilityFocused ()

Gets if this window has accessibility focus.

isActive

public boolean isActive ()

Gets if this window is active. An active window is the one the user is currently touching or the window has input focus and the user is not touching any window.

This is defined as the window that most recently fired one of the following events: AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED, AccessibilityEvent.TYPE_VIEW_HOVER_ENTER, AccessibilityEvent.TYPE_VIEW_HOVER_EXIT. In other words, the last window shown that also has input focus.

isFocused

public boolean isFocused ()

Gets if this window has input focus.

isInPictureInPictureMode

public boolean isInPictureInPictureMode ()

Check if the window is in picture-in-picture mode.

obtain

public static AccessibilityWindowInfo obtain ()

Returns a cached instance if such is available or a new one is created.

In most situations object pooling is not beneficial. Create a new instance using the constructor AccessibilityWindowInfo() instead.

obtain

public static AccessibilityWindowInfo obtain (AccessibilityWindowInfo info)

Returns a cached instance if such is available or a new one is created. The returned instance is initialized from the given info.

In most situations object pooling is not beneficial. Create a new instance using the constructor AccessibilityWindowInfo(android.view.accessibility.AccessibilityWindowInfo) instead.

recycle

public void recycle ()

Return an instance back to be reused.

Note: You must not touch the object after calling this function.

In most situations object pooling is not beneficial, and recycling is not necessary.

toString

public String toString ()

Returns a string representation of the object.

writeToParcel

public void writeToParcel (Parcel parcel, 
                int flags)

Flatten this object in to a Parcel.
