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.)

Constant Value: 1 (0x00000001)

LAYOUT_DIRECTION_INHERIT

public static final int LAYOUT_DIRECTION_INHERIT

Horizontal layout direction of this view is inherited from its parent. Use with setLayoutDirection(View, int).

Constant Value: 2 (0x00000002)

Horizontal layout direction of this view is from deduced from the default language script for the locale. Use with setLayoutDirection(View, int).

Constant Value: 3 (0x00000003)

LAYOUT_DIRECTION_LTR

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

                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.

`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

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,

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

hasNestedScrollingParent

`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)

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:

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:

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.

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.

Parameters
`v`	`View`
`delegate`	`AccessibilityDelegateCompat`: the object to which accessibility method calls should be delegated

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

Parameters

view

View: The view to set if it is a heading.

isHeading

boolean: true if the view is a heading, false otherwise.

Compatibility:

API < 19: No-op

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.

Parameters

view

View: The view on which to set the live region mode

mode

int: The live region mode for this view, one of:

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.

Parameters

view

View: The view whose pane title should be set.

accessibilityPaneTitle

CharSequence: The pane's title. Setting to null indicates that this View is not a pane.

Compatibility:

API < 19: No-op

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.

Parameters
`view`	`View`
`activated`	`boolean`: true if the view must be activated, false otherwise

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.

Parameters
`view`	`View`
`value`	`float`: The opacity of the view. Value is between 0.0 and 1.0 inclusive.

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.

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

Parameters
`v`	`View`
`autofillHints`	`String`: The autofill hints to set. If the array is emtpy, `null` is set. `R.attr.autofillHints`

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).

Parameters
`view`	`View`
`background`	`Drawable`

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.

Parameters
`view`	`View`
`tintList`	`ColorStateList`

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.

Parameters
`view`	`View`
`mode`	`PorterDuff.Mode`

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).

Parameters

viewGroup

ViewGroup

enabled

boolean: true if the order of the children when drawing is determined by ViewGroup.getChildDrawingOrder(int, int), false otherwise

Prior to API 7 this will have no effect.

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.

Parameters
`view`	`View`: The view to set clipBounds.
`clipBounds`	`Rect`: The rectangular area, in the local coordinates of this view, to which future drawing operations will be clipped.

setElevation

public static void setElevation (View view, 
                float elevation)

Sets the base elevation of this view, in pixels.

Parameters
`view`	`View`
`elevation`	`float`

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.

Parameters
`view`	`View`
`fitSystemWindows`	`boolean`

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.

Parameters
`view`	`View`
`isFocusedByDefault`	`boolean`: `true` to set `view` as the default-focus view, `false` otherwise.

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.

Parameters
`view`	`View`: View tracking transient state
`hasTransientState`	`boolean`: true if this view has transient state

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.

Parameters
`view`	`View`: The view whose property to set.
`mode`	`int`: How to determine whether this view is important for accessibility.

See also:

setImportantForAutofill

public static void setImportantForAutofill (View v, 
                int mode)

Sets the mode for determining whether this view is considered important for autofill.

The platform determines the importance for autofill automatically but you can use this method to customize the behavior. For example:

When the view contents is irrelevant for autofill (for example, a text field used in a "Captcha" challenge), it should be View.IMPORTANT_FOR_AUTOFILL_NO.
When both the view and its children are irrelevant for autofill (for example, the root view of an activity containing a spreadhseet editor), it should be View.IMPORTANT_FOR_AUTOFILL_NO_EXCLUDE_DESCENDANTS.
When the view content is relevant for autofill but its children aren't (for example, a credit card expiration date represented by a custom view that overrides the proper autofill methods and has 2 children representing the month and year), it should be View.IMPORTANT_FOR_AUTOFILL_YES_EXCLUDE_DESCENDANTS.

NOTE: setting the mode as does View.IMPORTANT_FOR_AUTOFILL_NO or View.IMPORTANT_FOR_AUTOFILL_NO_EXCLUDE_DESCENDANTS does not guarantee the view (and its children) will be always be considered not important; for example, when the user explicitly makes an autofill request, all views are considered important. See isImportantForAutofill(View) for more details about how the View's importance for autofill is used.

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

Parameters

v View

mode int: View.IMPORTANT_FOR_AUTOFILL_AUTO, View.IMPORTANT_FOR_AUTOFILL_YES, View.IMPORTANT_FOR_AUTOFILL_NO, View.IMPORTANT_FOR_AUTOFILL_YES_EXCLUDE_DESCENDANTS, or View.IMPORTANT_FOR_AUTOFILL_NO_EXCLUDE_DESCENDANTS. R.attr.importantForAutofill

setKeyboardNavigationCluster

public static void setKeyboardNavigationCluster (View view, boolean isCluster)

labeledId int: The labeled view id.

setLayerPaint

public static void setLayerPaint (View view, Paint paint)

Updates the Paint object used with the current layer (used only if the current layer type is not set to View.LAYER_TYPE_NONE). Changed properties of the Paint provided to setLayerType(android.view.View, int, android.graphics.Paint) will be used the next time the View is redrawn, but setLayerPaint(android.view.View, android.graphics.Paint) must be called to ensure that the view gets redrawn immediately.
A layer is associated with an optional Paint instance that controls how the layer is composed on screen. The following properties of the paint are taken into account when composing the layer:

Translucency (alpha)

Blending mode

Color filter

If this view has an alpha value set to < 1.0 by calling View#setAlpha(float), the alpha value of the layer's paint is replaced by this view's alpha value. Calling View#setAlpha(float) is therefore equivalent to setting a hardware layer on this view and providing a paint with the desired alpha value.

Parameters

view View: View to set a layer paint for

paint Paint: The paint used to compose the layer. This argument is optional and can be null. It is ignored when the layer type is View.LAYER_TYPE_NONE

See also:

setLayerType(View, int, android.graphics.Paint)

setLayerType

public static void setLayerType (View view, int layerType, Paint paint)

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

Specifies the type of layer backing this view. The layer can be disabled, software or hardware.

A layer is associated with an optional Paint instance that controls how the layer is composed on screen. The following properties of the paint are taken into account when composing the layer:

Translucency (alpha)

Blending mode

Color filter

If this view has an alpha value set to < 1.0 by calling setAlpha(float), the alpha value of the layer's paint is replaced by this view's alpha value. Calling setAlpha(float) is therefore equivalent to setting a hardware layer on this view and providing a paint with the desired alpha value.

Refer to the documentation of disabled, software and hardware for more information on when and how to use layers.

Parameters

view View: View to set the layer type for

layerType int: The type of layer to use with this view, must be one of View.LAYER_TYPE_NONE, View.LAYER_TYPE_SOFTWARE or View.LAYER_TYPE_HARDWARE

paint Paint: The paint used to compose the layer. This argument is optional and can be null. It is ignored when the layer type is View.LAYER_TYPE_NONE

setLayoutDirection

public static void setLayoutDirection (View view, int layoutDirection)

Set the layout direction for this view. This will propagate a reset of layout direction resolution to the view's children and resolve layout direction for this view.

Parameters

view View: View to set layout direction for

layoutDirection int: the layout direction to set. Should be one of: LAYOUT_DIRECTION_LTR, LAYOUT_DIRECTION_RTL, LAYOUT_DIRECTION_INHERIT, LAYOUT_DIRECTION_LOCALE. Resolution will be done if the value is set to LAYOUT_DIRECTION_INHERIT. The resolution proceeds up the parent chain of the view to get the value. If there is no parent, then it will return the default LAYOUT_DIRECTION_LTR.

setNestedScrollingEnabled

public static void setNestedScrollingEnabled (View view, boolean enabled)

Enable or disable nested scrolling for this view.
If this property is set to true the view will be permitted to initiate nested scrolling operations with a compatible parent view in the current hierarchy. If this view does not implement nested scrolling this will have no effect. Disabling nested scrolling while a nested scroll is in progress has the effect of stopping the nested scroll.

Parameters

view View

enabled boolean: true to enable nested scrolling, false to disable

See also:

isNestedScrollingEnabled(View)

setNextClusterForwardId

public static void setNextClusterForwardId (View view, int nextClusterForwardId)

setOverScrollMode

public static void setOverScrollMode (View v, int overScrollMode)

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

Set the over-scroll mode for this view. Valid over-scroll modes are OVER_SCROLL_ALWAYS (default), OVER_SCROLL_IF_CONTENT_SCROLLS (allow over-scrolling only if the view content is larger than the container), or OVER_SCROLL_NEVER. Setting the over-scroll mode of a view will have an effect only if the view is capable of scrolling.

Parameters

v View: The View against which to invoke the method.

overScrollMode int: The new over-scroll mode for this view.

setPaddingRelative

public static void setPaddingRelative (View view, int start, int top, int end, int bottom)

Sets the relative padding. The view may add on the space required to display the scrollbars, depending on the style and visibility of the scrollbars. So the values returned from getPaddingStart(View), View.getPaddingTop(), getPaddingEnd(View) and View.getPaddingBottom() may be different from the values set in this call.

Parameters

view View: The view on which to set relative padding

start int: the start padding in pixels

top int: the top padding in pixels

end int: the end padding in pixels

bottom int: the bottom padding in pixels

setPivotX

public static void setPivotX (View view, float value)

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