Constants

ACCESSIBILITY_LIVE_REGION_ASSERTIVE

public static final int ACCESSIBILITY_LIVE_REGION_ASSERTIVE

Live region mode specifying that accessibility services should interrupt ongoing speech to immediately announce changes to this view.

Use with setAccessibilityLiveRegion(View, int).

Constant Value: 2 (0x00000002)

ACCESSIBILITY_LIVE_REGION_NONE

public static final int ACCESSIBILITY_LIVE_REGION_NONE

Live region mode specifying that accessibility services should not automatically announce changes to this view. This is the default live region mode for most views.

Use with setAccessibilityLiveRegion(View, int).

Constant Value: 0 (0x00000000)

ACCESSIBILITY_LIVE_REGION_POLITE

public static final int ACCESSIBILITY_LIVE_REGION_POLITE

Live region mode specifying that accessibility services should announce changes to this view.

Use with setAccessibilityLiveRegion(View, int).

Constant Value: 1 (0x00000001)

IMPORTANT_FOR_ACCESSIBILITY_AUTO

public static final int IMPORTANT_FOR_ACCESSIBILITY_AUTO

Automatically determine whether a view is important for accessibility.

Constant Value: 0 (0x00000000)

IMPORTANT_FOR_ACCESSIBILITY_NO

public static final int IMPORTANT_FOR_ACCESSIBILITY_NO

The view is not important for accessibility.

Constant Value: 2 (0x00000002)

IMPORTANT_FOR_ACCESSIBILITY_NO_HIDE_DESCENDANTS

public static final int IMPORTANT_FOR_ACCESSIBILITY_NO_HIDE_DESCENDANTS

The view is not important for accessibility, nor are any of its descendant views.

Constant Value: 4 (0x00000004)

IMPORTANT_FOR_ACCESSIBILITY_YES

public static final int IMPORTANT_FOR_ACCESSIBILITY_YES

The view is important for accessibility.

Constant Value: 1 (0x00000001)

LAYER_TYPE_HARDWARE

public static final int LAYER_TYPE_HARDWARE

This constant is deprecated.
Use View.LAYER_TYPE_HARDWARE directly.

Indicates that the view has a hardware layer. A hardware layer is backed by a hardware specific texture (generally Frame Buffer Objects or FBO on OpenGL hardware) and causes the view to be rendered using Android's hardware rendering pipeline, but only if hardware acceleration is turned on for the view hierarchy. When hardware acceleration is turned off, hardware layers behave exactly as software layers.

A hardware layer is useful to apply a specific color filter and/or blending mode and/or translucency to a view and all its children.

A hardware layer can be used to cache a complex view tree into a texture and reduce the complexity of drawing operations. For instance, when animating a complex view tree with a translation, a hardware layer can be used to render the view tree only once.

A hardware layer can also be used to increase the rendering quality when rotation transformations are applied on a view. It can also be used to prevent potential clipping issues when applying 3D transforms on a view.

Constant Value: 2 (0x00000002)

LAYER_TYPE_NONE

public static final int LAYER_TYPE_NONE

This constant is deprecated.
Use View.LAYER_TYPE_NONE directly.

Indicates that the view does not have a layer.

Constant Value: 0 (0x00000000)

LAYER_TYPE_SOFTWARE

public static final int LAYER_TYPE_SOFTWARE

This constant is deprecated.
Use View.LAYER_TYPE_SOFTWARE directly.

Indicates that the view has a software layer. A software layer is backed by a bitmap and causes the view to be rendered using Android's software rendering pipeline, even if hardware acceleration is enabled.

Software layers have various usages:

When the application is not using hardware acceleration, a software layer is useful to apply a specific color filter and/or blending mode and/or translucency to a view and all its children.

When the application is using hardware acceleration, a software layer is useful to render drawing primitives not supported by the hardware accelerated pipeline. It can also be used to cache a complex view tree into a texture and reduce the complexity of drawing operations. For instance, when animating a complex view tree with a translation, a software layer can be used to render the view tree only once.

Software layers should be avoided when the affected view tree updates often. Every update will require to re-render the software layer, which can potentially be slow (particularly when hardware acceleration is turned on since the layer will have to be uploaded into a hardware texture after every update.)

public static boolean dispatchNestedFling (View view, 
                float velocityX, 
                float velocityY, 
                boolean consumed)

Dispatch a fling to a nested scrolling parent.

This method should be used to indicate that a nested scrolling child has detected suitable conditions for a fling. Generally this means that a touch scroll has ended with a velocity in the direction of scrolling that meets or exceeds the minimum fling velocity along a scrollable axis.

If a nested scrolling child view would normally fling but it is at the edge of its own content, it can use this method to delegate the fling to its nested scrolling parent instead. The parent may optionally consume the fling or observe a child fling.

Parameters
`view`	`View`
`velocityX`	`float`: Horizontal fling velocity in pixels per second
`velocityY`	`float`: Vertical fling velocity in pixels per second
`consumed`	`boolean`: true if the child consumed the fling, false otherwise

Returns
`boolean`	true if the nested scrolling parent consumed or otherwise reacted to the fling

dispatchNestedPreFling

public static boolean dispatchNestedPreFling (View view, 
                float velocityX, 
                float velocityY)

Dispatch a fling to a nested scrolling parent before it is processed by this view.

Nested pre-fling events are to nested fling events what touch intercept is to touch and what nested pre-scroll is to nested scroll. dispatchNestedPreFling offsets an opportunity for the parent view in a nested fling to fully consume the fling before the child view consumes it. If this method returns true, a nested parent view consumed the fling and this view should not scroll as a result.

For a better user experience, only one view in a nested scrolling chain should consume the fling at a time. If a parent view consumed the fling this method will return false. Custom view implementations should account for this in two ways:

If a custom view is paged and needs to settle to a fixed page-point, do not call dispatchNestedPreFling; consume the fling and settle to a valid position regardless.
If a nested parent does consume the fling, this view should not scroll at all, even to settle back to a valid idle position.

Views should also not offer fling velocities to nested parent views along an axis where scrolling is not currently supported; a ScrollView should not offer a horizontal fling velocity to its parents since scrolling along that axis is not permitted and carrying velocity along that motion does not make sense.

Parameters
`view`	`View`
`velocityX`	`float`: Horizontal fling velocity in pixels per second
`velocityY`	`float`: Vertical fling velocity in pixels per second

Returns
`boolean`	true if a nested scrolling parent consumed the fling

dispatchNestedPreScroll

                int dx, 
                int dy, 
                int[] consumed, 
                int[] offsetInWindow, 
                int type)

Dispatch one step of a nested scroll in progress before this view consumes any portion of it.

Nested pre-scroll events are to nested scroll events what touch intercept is to touch. dispatchNestedPreScroll offers an opportunity for the parent view in a nested scrolling operation to consume some or all of the scroll operation before the child view consumes it.

Parameters
`view`	`View`
`dx`	`int`: Horizontal scroll distance in pixels
`dy`	`int`: Vertical scroll distance in pixels
`consumed`	`int`: Output. If not null, consumed[0] will contain the consumed component of dx and consumed[1] the consumed dy.
`offsetInWindow`	`int`: Optional. If not null, on return this will contain the offset in local view coordinates of this view from before this operation to after it completes. View implementations may use this to adjust expected input coordinate tracking.
`type`	`int`: the type of input which cause this scroll event

Returns
`boolean`	true if the parent consumed some or all of the scroll delta

dispatchNestedScroll(View, int, int, int, int, int[])

dispatchNestedPreScroll

public static boolean dispatchNestedPreScroll (View view, 
                int dx, 
                int dy,

                int dyUnconsumed, 
                int[] offsetInWindow, 
                int type)

Dispatch one step of a nested scroll in progress.

Implementations of views that support nested scrolling should call this to report info about a scroll in progress to the current nested scrolling parent. If a nested scroll is not currently in progress or nested scrolling is not enabled for this view this method does nothing.

Compatible View implementations should also call dispatchNestedPreScroll before consuming a component of the scroll event themselves.

Parameters

`dxConsumed`	`int`: Horizontal distance in pixels consumed by this view during this scroll step
`dyConsumed`	`int`: Vertical distance in pixels consumed by this view during this scroll step

`dyUnconsumed`	`int`: Horizontal scroll distance in pixels not consumed by this view
`offsetInWindow`	`int`: Optional. If not null, on return this will contain the offset in local view coordinates of this view from before this operation to after it completes. View implementations may use this to adjust expected input coordinate tracking.
`type`	`int`: the type of input which cause this scroll event

Returns
`boolean`	true if the event was dispatched, and therefore the scroll distance was consumed

Compatible View implementations should also call dispatchNestedPreScroll before consuming a component of the scroll event themselves.

A non-null consumed int array of length 2 may be passed in to enable nested scrolling parents to report how much of the scroll distance was consumed. The original caller (where the input event was received to start the scroll) should initialize the values to be 0, in order to tell how much was actually consumed up the hierarchy of scrolling parents.

Parameters

Return the full width measurement information for this view as computed by the most recent call to View.measure(int, int). This result is a bit mask as defined by MEASURED_SIZE_MASK and MEASURED_STATE_TOO_SMALL. This should be used during measurement and layout calculations only. Use View.getWidth() to see how wide a view is after layout.

Parameters
`view`	`View`

Returns
`int`	The measured width of this view as a bit mask.

getMinimumHeight

public static int getMinimumHeight (View view)

Returns the minimum height of the view.

Prior to API 16, this method may return 0 on some platforms.

Parameters
`view`	`View`

Returns
`int`	the minimum height the view will try to be.

getMinimumWidth

public static int getMinimumWidth (View view)

Returns the minimum width of the view.

Prior to API 16, this method may return 0 on some platforms.

Parameters
`view`	`View`

Returns

getNextClusterForwardId

public static int getNextClusterForwardId (View view)

Gets the ID of the next keyboard navigation cluster root.

Parameters
`view`	`View`

Returns
`int`	the next keyboard navigation cluster ID, or `View.NO_ID` if the framework should decide automatically or API < 26.

getOnReceiveContentMimeTypes

public static String[] getOnReceiveContentMimeTypes (View view)

Returns the MIME types accepted by the listener configured on the given view via setOnReceiveContentListener(View, String[], OnReceiveContentListener). By default returns null.

Different features (e.g. pasting from the clipboard, inserting stickers from the soft keyboard, etc) may optionally use this metadata to conditionally alter their behavior. For example, a soft keyboard may choose to hide its UI for inserting GIFs for a particular input field if the MIME types returned here for that field don't include "image/gif" or "image/*".

Note: Comparisons of MIME types should be performed using utilities such as ClipDescription.compareMimeTypes(String, String) rather than simple string equality, in order to correctly handle patterns such as "text/*", "image/*", etc. Note that MIME type matching in the Android framework is case-sensitive, unlike formal RFC MIME types. As a result, you should always write your MIME types with lowercase letters, or use Intent.normalizeMimeType(String) to ensure that it is converted to lowercase.

Parameters
`view`	`View`: The target view.

Returns
`String[]`	The MIME types accepted by the `OnReceiveContentListener` for the given view (may include patterns such as "image/*").

Parameters
`view`	`View`

Returns
`boolean`	`true` if the view is focusable or if the view contains a focusable view, `false` otherwise

hasNestedScrollingParent

public static boolean hasNestedScrollingParent (View view, 
                int type)

Parameters
`view`	`View`
`type`	`int`: the type of input which cause this scroll event

Returns
`boolean`	whether this view has a nested scrolling parent

hasNestedScrollingParent

public static boolean hasNestedScrollingParent (View view)

Returns true if this view has a nested scrolling parent.

This version of the method just calls hasNestedScrollingParent(View, int) using the touch input type.

Parameters
`view`	`View`

Returns
`boolean`	whether this view has a nested scrolling parent

hasOnClickListeners

public static boolean hasOnClickListeners (View view)

Returns whether the provided view has an attached View.OnClickListener.

Parameters
`view`	`View`

Returns
`boolean`	true if there is a listener, false if there is none.

hasOverlappingRendering

public static boolean hasOverlappingRendering (View view)

Returns whether this View has content which overlaps.

This function, intended to be overridden by specific View types, is an optimization when alpha is set on a view. If rendering overlaps in a view with alpha < 1, that view is drawn to an offscreen buffer and then composited into place, which can be expensive. If the view has no overlapping rendering, the view can draw each primitive with the appropriate alpha value directly. An example of overlapping rendering is a TextView with a background image, such as a Button. An example of non-overlapping rendering is a TextView with no background, or an ImageView with only the foreground image. The default implementation returns true; subclasses should override if they have cases which can be optimized.

Parameters
`view`	`View`

Returns
`boolean`	true if the content in this view might overlap, false otherwise.

hasTransientState

public static boolean hasTransientState (View view)

Indicates whether the view is currently tracking transient state that the app should not need to concern itself with saving and restoring, but that the framework should take special note to preserve when possible.

Parameters
`view`	`View`

Returns
`boolean`	`true` if `view` is the default-focus view, `false` otherwise.

isImportantForAccessibility

public static boolean isImportantForAccessibility (View view)

Computes whether this view should be exposed for accessibility. In general, views that are interactive or provide information are exposed while views that serve only as containers are hidden.

If an ancestor of this view has importance IMPORTANT_FOR_ACCESSIBILITY_NO_HIDE_DESCENDANTS, this method returns false.

Otherwise, the value is computed according to the view's getImportantForAccessibility(View) value:

IMPORTANT_FOR_ACCESSIBILITY_NO or IMPORTANT_FOR_ACCESSIBILITY_NO_HIDE_DESCENDANTS, return false
IMPORTANT_FOR_ACCESSIBILITY_YES, return true
IMPORTANT_FOR_ACCESSIBILITY_AUTO, return true if view satisfies any of the following:
- Is actionable, e.g. View.isClickable(), View.isLongClickable(), or View.isFocusable()
- Has an AccessibilityDelegateCompat

onInitializeAccessibilityEvent

public static void onInitializeAccessibilityEvent (View v, 
                AccessibilityEvent event)

This method is deprecated.
Call View.onInitializeAccessibilityEvent(AccessibilityEvent) directly. This method will be removed in a future release.

Initializes an AccessibilityEvent with information about this View which is the event source. In other words, the source of an accessibility event is the view whose state change triggered firing the event.

Example: Setting the password property of an event in addition to properties set by the super implementation:

 public void onInitializeAccessibilityEvent(AccessibilityEvent event) {
     super.onInitializeAccessibilityEvent(event);
     event.setPassword(true);
 }

If an AccessibilityDelegateCompat has been specified via calling setAccessibilityDelegate(View, AccessibilityDelegateCompat), its AccessibilityDelegateCompat.onInitializeAccessibilityEvent(View, AccessibilityEvent) is responsible for handling this call.

Parameters
`v`	`View`: The View against which to invoke the method.
`event`	`AccessibilityEvent`: The event to initialize.

See also:

onInitializeAccessibilityNodeInfo

public static void onInitializeAccessibilityNodeInfo (View v, 
                AccessibilityNodeInfoCompat info)

Initializes an AccessibilityNodeInfoCompat with information about this view. The base implementation sets:

If an AccessibilityDelegateCompat has been specified via calling setAccessibilityDelegate(View, AccessibilityDelegateCompat), its AccessibilityDelegateCompat.onInitializeAccessibilityNodeInfo(View, AccessibilityNodeInfoCompat) method is responsible for handling this call.

Parameters
`v`	`View`: The View against which to invoke the method.
`info`	`AccessibilityNodeInfoCompat`: The instance to initialize.

onPopulateAccessibilityEvent

public static void onPopulateAccessibilityEvent (View v, 
                AccessibilityEvent event)

This method is deprecated.
Call View.onPopulateAccessibilityEvent(AccessibilityEvent) directly. This method will be removed in a future release.

Called from View.dispatchPopulateAccessibilityEvent(AccessibilityEvent) giving a chance to this View to populate the accessibility event with its text content. While this method is free to modify event attributes other than text content, doing so should normally be performed in View.onInitializeAccessibilityEvent(AccessibilityEvent).

Example: Adding formatted date string to an accessibility event in addition to the text added by the super implementation:

 public void onPopulateAccessibilityEvent(AccessibilityEvent event) {
     super.onPopulateAccessibilityEvent(event);
     final int flags = DateUtils.FORMAT_SHOW_DATE | DateUtils.FORMAT_SHOW_WEEKDAY;
     String selectedDateUtterance = DateUtils.formatDateTime(mContext,
         mCurrentDate.getTimeInMillis(), flags);
     event.getText().add(selectedDateUtterance);
 }

If an AccessibilityDelegateCompat has been specified via calling setAccessibilityDelegate(View, AccessibilityDelegateCompat) its AccessibilityDelegateCompat.onPopulateAccessibilityEvent(View, AccessibilityEvent) is responsible for handling this call.

Note: Always call the super implementation before adding information to the event, in case the default implementation has basic information to add.

Parameters
`v`	`View`: The View against which to invoke the method.
`event`	`AccessibilityEvent`: The accessibility event which to populate.

Parameters
`view`	`View`: The target view.
`payload`	`ContentInfoCompat`: The content to insert and related metadata.

Returns
`ContentInfoCompat`	The portion of the passed-in content that was not handled (may be all, some, or none of the passed-in content).
