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)

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.)

Constant Value: 1 (0x00000001)

public static final int MEASURED_SIZE_MASK

This constant is deprecated.
Use View.MEASURED_SIZE_MASK directly.

Bits of getMeasuredWidthAndState(View) and getMeasuredWidthAndState(View) that provide the actual measured size.

Constant Value: 16777215 (0x00ffffff)

MEASURED_STATE_MASK

public static final int MEASURED_STATE_MASK

This constant is deprecated.

This method returns a ViewPropertyAnimator object, which can be used to animate specific properties on this View.

canScrollHorizontally

public static boolean canScrollHorizontally (View view, 
                int direction)

This method is deprecated.
Use View.canScrollHorizontally(int) directly.

Check if this view can be scrolled horizontally in a certain direction.

canScrollVertically

public static boolean canScrollVertically (View view, 
                int direction)

Cancel the drag and drop operation.

combineMeasuredStates

public static int combineMeasuredStates (int curState, 
                int newState)

computeSystemWindowInsets

public static WindowInsetsCompat computeSystemWindowInsets (View view, 
                WindowInsetsCompat insets, 
                Rect outLocalInsets)

Compute insets that should be consumed by this view and the ones that should propagate to those under it.

dispatchApplyWindowInsets

public static WindowInsetsCompat dispatchApplyWindowInsets (View view, 
                WindowInsetsCompat insets)

Request to apply the given window insets to this view or another view in its subtree.

This method should be called by clients wishing to apply insets corresponding to areas obscured by window decorations or overlays. This can include the status and navigation bars, action bars, input methods and more. New inset categories may be added in the future. The method returns the insets provided minus any that were applied by this view or its children.

dispatchFinishTemporaryDetach

public static void dispatchFinishTemporaryDetach (View view)

Notify a view that its temporary detach has ended; the view is now reattached.

dispatchNestedFling

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.

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.

dispatchNestedPreScroll

public static boolean dispatchNestedPreScroll (View view, 
                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.

dispatchNestedPreScroll

public static boolean dispatchNestedPreScroll (View view, 
                int dx, 
                int dy, 
                int[] consumed, 
                int[] offsetInWindow)

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

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

dispatchNestedScroll

public static boolean dispatchNestedScroll (View view, 
                int dxConsumed, 
                int dyConsumed, 
                int dxUnconsumed, 
                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.

dispatchNestedScroll

public static boolean dispatchNestedScroll (View view, 
                int dxConsumed, 
                int dyConsumed, 
                int dxUnconsumed, 
                int dyUnconsumed, 
                int[] offsetInWindow)

Dispatch one step of a nested scroll in progress.

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

dispatchNestedScroll

public static void dispatchNestedScroll (View view, 
                int dxConsumed, 
                int dyConsumed, 
                int dxUnconsumed, 
                int dyUnconsumed, 
                int[] offsetInWindow, 
                int type, 
                int[] consumed)

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.

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.

To check whether the bottom scroll indicator is enabled, use the value of (ViewCompat.getScrollIndicators(view) & ViewCompat.SCROLL_INDICATOR_BOTTOM) != 0.

getStateDescription

public static final CharSequence getStateDescription (View view)

Returns the View's state description.

Note: Do not override this method, as it will have no effect on the state description presented to accessibility services. You must call setStateDescription(View, CharSequence) to modify the state description.

Checks whether provided View has an accessibility delegate attached to it.

hasExplicitFocusable

public static boolean hasExplicitFocusable (View view)

Returns true if this view is focusable or if it contains a reachable View for which View.hasExplicitFocusable() returns true. A "reachable hasExplicitFocusable()" is a view whose parents do not block descendants focus. Only View.VISIBLE views for which View.getFocusable() would return View.FOCUSABLE are considered focusable.

This method preserves the pre-Build.VERSION_CODES.O behavior of View.hasFocusable() in that only views explicitly set focusable will cause this method to return true. A view set to View.FOCUSABLE_AUTO that resolves to focusable will not.

hasNestedScrollingParent

public static boolean hasNestedScrollingParent (View view, 
                int type)

Returns true if this view has a nested scrolling parent.

The presence of a nested scrolling parent indicates that this view has initiated a nested scroll and it was accepted by an ancestor view further up the view hierarchy.

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.

hasOnClickListeners

public static boolean hasOnClickListeners (View view)

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

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.

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.

isAccessibilityHeading

public static boolean isAccessibilityHeading (View view)

Gets whether this view is a heading for accessibility purposes.

isAttachedToWindow

public static boolean isAttachedToWindow (View view)

Returns true if the provided view is currently attached to a window.

isFocusedByDefault

public static boolean isFocusedByDefault (View view)

Returns whether view should receive focus when the focus is restored for the view hierarchy containing it. Returns false on API < 26.

Focus gets restored for a view hierarchy when the root of the hierarchy gets added to a window or serves as a target of cluster navigation.

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:

1. IMPORTANT_FOR_ACCESSIBILITY_NO or IMPORTANT_FOR_ACCESSIBILITY_NO_HIDE_DESCENDANTS, return false
2. IMPORTANT_FOR_ACCESSIBILITY_YES, return true
3. 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
   • Has an interaction listener, e.g. View.OnTouchListener, View.OnKeyListener, etc.
   • Is an accessibility live region, e.g. getAccessibilityLiveRegion(View) is not ACCESSIBILITY_LIVE_REGION_NONE.

Note: Prior to API 21, this method will always return true.

isImportantForAutofill

public static boolean isImportantForAutofill (View v)

Hints the Android System whether the AssistStructure.ViewNode associated with this view is considered important for autofill purposes.

Generally speaking, a view is important for autofill if:

1. The view can be autofilled by an AutofillService.
2. The view contents can help an AutofillService determine how other views can be autofilled.

   For example, view containers should typically return false for performance reasons (since the important info is provided by their children), but if its properties have relevant information (for example, a resource id called credentials, it should return true. On the other hand, views representing labels or editable fields should typically return true, but in some cases they could return false (for example, if they're part of a "Captcha" mechanism).

   The value returned by this method depends on the value returned by getImportantForAutofill(View):

   1. if it returns View.IMPORTANT_FOR_AUTOFILL_YES or View.IMPORTANT_FOR_AUTOFILL_YES_EXCLUDE_DESCENDANTS, then it returns true
   2. if it returns View.IMPORTANT_FOR_AUTOFILL_NO or View.IMPORTANT_FOR_AUTOFILL_NO_EXCLUDE_DESCENDANTS, then it returns false
   3. if it returns View.IMPORTANT_FOR_AUTOFILL_AUTO, then it uses some simple heuristics that can return true in some cases (like a container with a resource id), but false in most.
   4. otherwise, it returns false.

   When a view is considered important for autofill:

   • The view might automatically trigger an autofill request when focused on.
   • The contents of the view are included in the ViewStructure used in an autofill request.

   On the other hand, when a view is considered not important for autofill:

   • The view never automatically triggers autofill requests, but it can trigger a manual request through AutofillManager.requestAutofill(View).
   • The contents of the view are not included in the ViewStructure used in an autofill request, unless the request has the View.AUTOFILL_FLAG_INCLUDE_NOT_IMPORTANT_VIEWS flag.

   This method is only supported on API >= 26. On API 25 and below, it will always return true.

   Parameters
   v	View

   Returns
   boolean	whether the view is considered important for autofill.

   See also:

   • setImportantForAutofill(View, int)
   • View.IMPORTANT_FOR_AUTOFILL_AUTO
   • View.IMPORTANT_FOR_AUTOFILL_YES
   • View.IMPORTANT_FOR_AUTOFILL_NO
   • View.IMPORTANT_FOR_AUTOFILL_YES_EXCLUDE_DESCENDANTS
   • View.IMPORTANT_FOR_AUTOFILL_NO_EXCLUDE_DESCENDANTS
   • AutofillManager.requestAutofill(View)

isInLayout

public static boolean isInLayout (View view)

Returns whether the view hierarchy is currently undergoing a layout pass. This information is useful to avoid situations such as calling View.requestLayout() during a layout pass.

Compatibility:

• API < 18: Always returns false

isKeyboardNavigationCluster

public static boolean isKeyboardNavigationCluster (View view)

Returns whether view is a root of a keyboard navigation cluster. Always returns false on API < 26.

isLaidOut

public static boolean isLaidOut (View view)

Returns true if view has been through at least one layout since it was last attached to or detached from a window.

isLayoutDirectionResolved

public static boolean isLayoutDirectionResolved (View view)

Returns whether layout direction has been resolved.

Compatibility:

• API < 19: Always returns false

isNestedScrollingEnabled

public static boolean isNestedScrollingEnabled (View view)

Returns true if nested scrolling is enabled for this view.

If nested scrolling is enabled and this View class implementation supports it, this view will act as a nested scrolling child view when applicable, forwarding data about the scroll operation in progress to a compatible and cooperating nested scrolling parent.

isOpaque

public static boolean isOpaque (View view)

This method is deprecated.
Use View.isOpaque() directly. This method will be removed in a future release.

Indicates whether this View is opaque. An opaque View guarantees that it will draw all the pixels overlapping its bounds using a fully opaque color.

isPaddingRelative

public static boolean isPaddingRelative (View view)

Return if the padding as been set through relative values View.setPaddingRelative(int, int, int, int) or thru

isScreenReaderFocusable

public static boolean isScreenReaderFocusable (View view)

Returns whether the view should be treated as a focusable unit by screen reader accessibility tools.

jumpDrawablesToCurrentState

public static void jumpDrawablesToCurrentState (View v)

This method is deprecated.
Use View.jumpDrawablesToCurrentState() directly.

On API 11 devices and above, call Drawable.jumpToCurrentState() on all Drawable objects associated with this view.

On API 21 and above, also calls StateListAnimator#jumpToCurrentState() if there is a StateListAnimator attached to this view.

keyboardNavigationClusterSearch

public static View keyboardNavigationClusterSearch (View view, 
                View currentCluster, 
                int direction)

Find the nearest keyboard navigation cluster in the specified direction. This does not actually give focus to that cluster.

offsetLeftAndRight

public static void offsetLeftAndRight (View view, 
                int offset)

Offset this view's horizontal location by the specified amount of pixels.

offsetTopAndBottom

public static void offsetTopAndBottom (View view, 
                int offset)

Offset this view's vertical location by the specified number of pixels.

onApplyWindowInsets

public static WindowInsetsCompat onApplyWindowInsets (View view, 
                WindowInsetsCompat insets)

Called when the view should apply WindowInsetsCompat according to its internal policy.

Clients may supply an OnApplyWindowInsetsListener to a view. If one is set it will be called during dispatch instead of this method. The listener may optionally call this method from its own implementation if it wishes to apply the view's default insets policy in addition to its own.

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.

onInitializeAccessibilityNodeInfo

public static void onInitializeAccessibilityNodeInfo (View v, 
                AccessibilityNodeInfoCompat info)

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

• AccessibilityNodeInfoCompat.setParent(View),
• AccessibilityNodeInfoCompat.setBoundsInParent(Rect),
• AccessibilityNodeInfoCompat.setBoundsInScreen(Rect),
• AccessibilityNodeInfoCompat.setPackageName(CharSequence),
• AccessibilityNodeInfoCompat.setClassName(CharSequence),
• AccessibilityNodeInfoCompat.setContentDescription(CharSequence),
• AccessibilityNodeInfoCompat.setStateDescription(CharSequence),
• AccessibilityNodeInfoCompat.setEnabled(boolean),
• AccessibilityNodeInfoCompat.setClickable(boolean),
• AccessibilityNodeInfoCompat.setFocusable(boolean),
• AccessibilityNodeInfoCompat.setFocused(boolean),
• AccessibilityNodeInfoCompat.setLongClickable(boolean),
• AccessibilityNodeInfoCompat.setSelected(boolean),

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

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.

performAccessibilityAction

public static boolean performAccessibilityAction (View view, 
                int action, 
                Bundle arguments)

Performs the specified accessibility action on the view. For possible accessibility actions look at AccessibilityNodeInfoCompat.

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

postInvalidateOnAnimation

public static void postInvalidateOnAnimation (View view, 
                int left, 
                int top, 
                int right, 
                int bottom)

Cause an invalidate of the specified area to happen on the next animation time step, typically the next display frame.

This method can be invoked from outside of the UI thread only when this View is attached to a window.

postInvalidateOnAnimation

public static void postInvalidateOnAnimation (View view)

Cause an invalidate to happen on the next animation time step, typically the next display frame.

This method can be invoked from outside of the UI thread only when this View is attached to a window.

postOnAnimation

public static void postOnAnimation (View view, 
                Runnable action)

Causes the Runnable to execute on the next animation time step. The runnable will be run on the user interface thread.

This method can be invoked from outside of the UI thread only when this View is attached to a window.

postOnAnimationDelayed

public static void postOnAnimationDelayed (View view, 
                Runnable action, 
                long delayMillis)

Causes the Runnable to execute on the next animation time step, after the specified amount of time elapses. The runnable will be run on the user interface thread.

This method can be invoked from outside of the UI thread only when this View is attached to a window.

removeAccessibilityAction

public static void removeAccessibilityAction (View view, 
                int actionId)

Removes an accessibility action that can be performed on a node associated with a view. If the action was not already added to the view, calling this method has no effect.

removeOnUnhandledKeyEventListener

public static void removeOnUnhandledKeyEventListener (View v, 
                ViewCompat.OnUnhandledKeyEventListenerCompat listener)

Removes a listener which will receive unhandled KeyEvents. This must be called on the UI thread.

replaceAccessibilityAction

public static void replaceAccessibilityAction (View view, 
                AccessibilityNodeInfoCompat.AccessibilityActionCompat replacedAction, 
                CharSequence label, 
                AccessibilityViewCommand command)

Replaces an action. This can be used to change the default behavior or label of the action specified. If label and command are both null, the action will be removed.

requestApplyInsets

public static void requestApplyInsets (View view)

Ask that a new dispatch of View.onApplyWindowInsets(WindowInsets) be performed. This falls back to View.requestFitSystemWindows() where available.

requireViewById

public static T requireViewById (View view, 
                int id)

Finds the first descendant view with the given ID, the view itself if the ID matches View.getId(), or throws an IllegalArgumentException if the ID is invalid or there is no matching view in the hierarchy.

Note: In most cases -- depending on compiler support -- the resulting view is automatically cast to the target class type. If the target class type is unconstrained, an explicit cast may be necessary.

resolveSizeAndState

public static int resolveSizeAndState (int size, 
                int measureSpec, 
                int childMeasuredState)

This method is deprecated.
Use View.resolveSizeAndState(int, int, int) directly.

Utility to reconcile a desired size and state, with constraints imposed by a MeasureSpec. Will take the desired size, unless a different size is imposed by the constraints. The returned value is a compound integer, with the resolved size in the MEASURED_SIZE_MASK bits and optionally the bit MEASURED_STATE_TOO_SMALL set if the resulting size is smaller than the size the view wants to be.

restoreDefaultFocus

public static boolean restoreDefaultFocus (View view)

Gives focus to the default-focus view in the view hierarchy rooted at view. If the default-focus view cannot be found or if API < 26, this falls back to calling View.requestFocus(int).

saveAttributeDataForStyleable

public static void saveAttributeDataForStyleable (View view, 
                Context context, 
                int[] styleable, 
                AttributeSet attrs, 
                TypedArray t, 
                int defStyleAttr, 
                int defStyleRes)

Stores debugging information about attributes. This should be called in a constructor by every custom View that uses a custom styleable. If the custom view does not call it, then the custom attributes used by this view will not be visible in layout inspection tools. No-op before API 29.

setAccessibilityDelegate

public static void setAccessibilityDelegate (View v, 
                AccessibilityDelegateCompat delegate)

Sets a delegate for implementing accessibility support via composition (as opposed to inheritance). For more details, see AccessibilityDelegateCompat.

Note: On platform versions prior to API 23, delegate methods on views in the android.widget.* package are called before host methods. This prevents certain properties such as class name from being modified by overriding AccessibilityDelegateCompat.onInitializeAccessibilityNodeInfo(View, AccessibilityNodeInfoCompat), as any changes will be overwritten by the host class.

Starting in API 23, delegate methods are called after host methods, which all properties to be modified without being overwritten by the host class.

If an AccessibilityDelegateCompat is already attached to the view, and this method sets the delegate to null, an empty delegate will be attached to ensure that other compatibility behavior continues to work for this view.

setAccessibilityHeading

public static void setAccessibilityHeading (View view, 
                boolean isHeading)

Set if view is a heading for a section of content for accessibility purposes.

setAccessibilityLiveRegion

public static void setAccessibilityLiveRegion (View view, 
                int mode)

Sets the live region mode for the specified view. This indicates to accessibility services whether they should automatically notify the user about changes to the view's content description or text, or to the content descriptions or text of the view's children (where applicable).

For example, in a login screen with a TextView that displays an "incorrect password" notification, that view should be marked as a live region with mode ACCESSIBILITY_LIVE_REGION_POLITE.

To disable change notifications for this view, use ACCESSIBILITY_LIVE_REGION_NONE. This is the default live region mode for most views.

To indicate that the user should be notified of changes, use ACCESSIBILITY_LIVE_REGION_POLITE.

If the view's changes should interrupt ongoing speech and notify the user immediately, use ACCESSIBILITY_LIVE_REGION_ASSERTIVE.

setAccessibilityPaneTitle

public static void setAccessibilityPaneTitle (View view, 
                CharSequence accessibilityPaneTitle)

Visually distinct portion of a window with window-like semantics are considered panes for accessibility purposes. One example is the content view of a fragment that is replaced. In order for accessibility services to understand a pane's window-like behavior, panes should have descriptive titles. Views with pane titles produce AccessibilityEvents when they appear, disappear, or change title.

setActivated

public static void setActivated (View view, 
                boolean activated)

This method is deprecated.
Use View.setActivated(boolean) directly.

Changes the activated state of this view. A view can be activated or not. Note that activation is not the same as selection. Selection is a transient property, representing the view (hierarchy) the user is currently interacting with. Activation is a longer-term state that the user can move views in and out of.

setAlpha

public static void setAlpha (View view, 
                float value)

This method is deprecated.
Use View.setAlpha(float) directly.

Sets the opacity of the view. This is a value from 0 to 1, where 0 means the view is completely transparent and 1 means the view is completely opaque.

Note that setting alpha to a translucent value (0 < alpha < 1) can have significant performance implications, especially for large views. It is best to use the alpha property sparingly and transiently, as in the case of fading animations.

setAutofillHints

public static void setAutofillHints (View v, 
                String... autofillHints)

Sets the hints that help an AutofillService determine how to autofill the view with the user's data.

Typically, there is only one way to autofill a view, but there could be more than one. For example, if the application accepts either an username or email address to identify an user.

These hints are not validated by the Android System, but passed "as is" to the service. Hence, they can have any value, but it's recommended to use the AUTOFILL_HINT_ constants such as: View.AUTOFILL_HINT_USERNAME, View.AUTOFILL_HINT_PASSWORD, View.AUTOFILL_HINT_EMAIL_ADDRESS, View.AUTOFILL_HINT_NAME, View.AUTOFILL_HINT_PHONE, View.AUTOFILL_HINT_POSTAL_ADDRESS, View.AUTOFILL_HINT_POSTAL_CODE, View.AUTOFILL_HINT_CREDIT_CARD_NUMBER, View.AUTOFILL_HINT_CREDIT_CARD_SECURITY_CODE, View.AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_DATE, View.AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_DAY, View.AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_MONTH or View.AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_YEAR.

This method is only supported on API >= 26. On API 25 and below, it is a no-op

setBackground

public static void setBackground (View view, 
                Drawable background)

Set the background of the view to a given Drawable, or remove the background. If the background has padding, view's padding is set to the background's padding. However, when a background is removed, this View's padding isn't touched. If setting the padding is desired, please usesetPadding(int, int, int, int).

setBackgroundTintList

public static void setBackgroundTintList (View view, 
                ColorStateList tintList)

Applies a tint to the background drawable.

This will always take effect when running on API v21 or newer. When running on platforms previous to API v21, it will only take effect if view implements the TintableBackgroundView interface.

setBackgroundTintMode

public static void setBackgroundTintMode (View view, 
                PorterDuff.Mode mode)

Specifies the blending mode used to apply the tint specified by setBackgroundTintList(android.view.View, android.content.res.ColorStateList) to the background drawable. The default mode is PorterDuff.Mode.SRC_IN.

This will always take effect when running on API v21 or newer. When running on platforms previous to API v21, it will only take effect if view implement the TintableBackgroundView interface.

setChildrenDrawingOrderEnabled

public static void setChildrenDrawingOrderEnabled (ViewGroup viewGroup, 
                boolean enabled)

This method is deprecated.
Use ViewGroup.setChildrenDrawingOrderEnabled(boolean) directly.

Tells the ViewGroup whether to draw its children in the order defined by the method ViewGroup.getChildDrawingOrder(int, int).

setClipBounds

public static void setClipBounds (View view, 
                Rect clipBounds)

Sets a rectangular area on this view to which the view will be clipped when it is drawn. Setting the value to null will remove the clip bounds and the view will draw normally, using its full bounds.

Prior to API 18 this does nothing.

setElevation

public static void setElevation (View view, 
                float elevation)

Sets the base elevation of this view, in pixels.

setFitsSystemWindows

public static void setFitsSystemWindows (View view, 
                boolean fitSystemWindows)

This method is deprecated.
Use View.setFitsSystemWindows(boolean) directly.

Sets whether or not this view should account for system screen decorations such as the status bar and inset its content; that is, controlling whether the default implementation of View.fitSystemWindows(Rect) will be executed. See that method for more details.

setFocusedByDefault

public static void setFocusedByDefault (View view, 
                boolean isFocusedByDefault)

Sets whether view should receive focus when the focus is restored for the view hierarchy containing it.

Focus gets restored for a view hierarchy when the root of the hierarchy gets added to a window or serves as a target of cluster navigation.

Does nothing on API < 26.

setHasTransientState

public static void setHasTransientState (View view, 
                boolean hasTransientState)

Set whether this view is currently tracking transient state that the framework should attempt to preserve when possible.

setImportantForAccessibility

public static void setImportantForAccessibility (View view, 
                int mode)

Sets how to determine whether this view is important for accessibility which is if it fires accessibility events and if it is reported to accessibility services that query the screen.

Note: If the current platform version does not support the IMPORTANT_FOR_ACCESSIBILITY_NO_HIDE_DESCENDANTS mode, then IMPORTANT_FOR_ACCESSIBILITY_NO will be used as it is the closest terms of semantics.
