Constants
ACCESSIBILITY_LIVE_REGION_ASSERTIVE
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
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
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
int IMPORTANT_FOR_ACCESSIBILITY_AUTO
Automatically determine whether a view is important for accessibility.
Constant Value: 0 (0x00000000)
IMPORTANT_FOR_ACCESSIBILITY_NO
int IMPORTANT_FOR_ACCESSIBILITY_NO
The view is not important for accessibility.
Constant Value: 2 (0x00000002)
IMPORTANT_FOR_ACCESSIBILITY_NO_HIDE_DESCENDANTS
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
int IMPORTANT_FOR_ACCESSIBILITY_YES
The view is important for accessibility.
Constant Value: 1 (0x00000001)
LAYER_TYPE_HARDWARE
int LAYER_TYPE_HARDWARE
This constant was deprecated
in API level 26.1.0.
Use 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
int LAYER_TYPE_NONE
This constant was deprecated
in API level 26.1.0.
Use LAYER_TYPE_NONE
directly.
Indicates that the view does not have a layer.
Constant Value: 0 (0x00000000)
LAYER_TYPE_SOFTWARE
int LAYER_TYPE_SOFTWARE
This constant was deprecated
in API level 26.1.0.
Use 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
int LAYOUT_DIRECTION_INHERIT
Horizontal layout direction of this view is inherited from its parent.
Use with setLayoutDirection(View, int)
.
Constant Value: 2 (0x00000002)
LAYOUT_DIRECTION_LOCALE
int LAYOUT_DIRECTION_LOCALE
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
int LAYOUT_DIRECTION_LTR
Horizontal layout direction of this view is from Left to Right.
Constant Value: 0 (0x00000000)
LAYOUT_DIRECTION_RTL
int LAYOUT_DIRECTION_RTL
Horizontal layout direction of this view is from Right to Left.
Constant Value: 1 (0x00000001)
MEASURED_HEIGHT_STATE_SHIFT
int MEASURED_HEIGHT_STATE_SHIFT
This constant was deprecated
in API level 26.1.0.
Use MEASURED_HEIGHT_STATE_SHIFT
directly.
Bit shift of MEASURED_STATE_MASK
to get to the height bits
for functions that combine both width and height into a single int,
such as getMeasuredState(View)
and the childState argument of
resolveSizeAndState(int, int, int)
.
Constant Value: 16 (0x00000010)
MEASURED_SIZE_MASK

dispatchFinishTemporaryDetach
void dispatchFinishTemporaryDetach (View view)
Notify a view that its temporary detach has ended; the view is now reattached.
Parameters | |
---|---|
view |
View |
dispatchNestedFling
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
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
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.

scrolling operation to consume some or all of the scroll operation before the child view
consumes it.

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 |
dispatchNestedPreScroll
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.

dispatchNestedScroll
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.

hasExplicitFocusable
boolean hasExplicitFocusable (View view)
Returns true if this view is focusable or if it contains a reachable View
for which hasExplicitFocusable()
returns true
.
A "reachable hasExplicitFocusable()" is a view whose parents do not block descendants focus.
Only VISIBLE
views for which getFocusable()
would return
FOCUSABLE
are considered focusable.
This method preserves the pre-O
behavior of
hasFocusable()
in that only views explicitly set focusable will cause
this method to return true. A view set to FOCUSABLE_AUTO
that resolves
to focusable will not.
Parameters | |
---|---|
view |
View |
Returns | |
---|---|
boolean |
true if the view is focusable or if the view contains a focusable
view, false otherwise
|
hasNestedScrollingParent
boolean hasNestedScrollingParent (View view, int type)
Returns true if this view has a nested scrolling parent.

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
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
boolean hasOnClickListeners (View view)
Returns whether the provided view has an attached View.OnClickListener
.
Parameters | |
---|---|

View |
Returns | |
---|---|
boolean |
true if there is a listener, false if there is none. |
hasOverlappingRendering
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
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 : View to check for transient state |
Returns | |
---|---|
boolean |
true if the view has transient state |
isAttachedToWindow
boolean isAttachedToWindow (View view)
Returns true if the provided view is currently attached to a window.
Parameters | |
---|---|
view |
View |
Returns | |
---|---|
boolean |
isFocusedByDefault
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.
Parameters | |
---|---|
view |
View |
Returns | |
---|---|
boolean |
true if view is the default-focus view, false otherwise.
|
isImportantForAccessibility
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
orIMPORTANT_FOR_ACCESSIBILITY_NO_HIDE_DESCENDANTS
, returnfalse
IMPORTANT_FOR_ACCESSIBILITY_YES
, returntrue
IMPORTANT_FOR_ACCESSIBILITY_AUTO
, returntrue
if view satisfies any of the following:- Is actionable, e.g.
isClickable()
,isLongClickable()
, orisFocusable()
- Has an
AccessibilityDelegateCompat
- Has an interaction listener, e.g.
View.OnTouchListener
,View.OnKeyListener
, etc. - Is an accessibility live region, e.g.
getAccessibilityLiveRegion(View)
is notACCESSIBILITY_LIVE_REGION_NONE
.
- Is actionable, e.g.
Note: Prior to API 21, this method will always return true
.

Returns | |
---|---|
boolean |
Whether the view is exposed for accessibility. |
isImportantForAutofill
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:
- The view can be autofilled by an
AutofillService
. - The view contents can help an
AutofillService
determine how other views can be autofilled.- if it returns
IMPORTANT_FOR_AUTOFILL_YES
orIMPORTANT_FOR_AUTOFILL_YES_EXCLUDE_DESCENDANTS
, then it returnstrue
- if it returns
IMPORTANT_FOR_AUTOFILL_NO
orIMPORTANT_FOR_AUTOFILL_NO_EXCLUDE_DESCENDANTS
, then it returnsfalse
- if it returns
IMPORTANT_FOR_AUTOFILL_AUTO
, then it uses some simple heuristics that can returntrue
in some cases (like a container with a resource id), butfalse
in most. - otherwise, it returns
false
. - 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. - The view never automatically triggers autofill requests, but it can trigger a manual
request through
requestAutofill(View)
. - The contents of the view are not included in the
ViewStructure
used in an autofill request, unless the request has theAUTOFILL_FLAG_INCLUDE_NOT_IMPORTANT_VIEWS
flag.
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 calledcredentials
, it should returntrue
. On the other hand, views representing labels or editable fields should typically returntrue
, but in some cases they could returnfalse
(for example, if they're part of a "Captcha" mechanism).The value returned by this method depends on the value returned by
getImportantForAutofill(View)
:When a view is considered important for autofill:
On the other hand, when a view is considered not important for autofill:
This method is only supported on API >= 26. On API 25 and below, it will always return
true

in API level 26.1.0.
Call 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
onInitializeAccessibilityEvent(View, AccessibilityEvent)
is responsible for handling this call.

,setContentDescription(CharSequence)
,setEnabled(boolean)
,setClickable(boolean)
,setFocusable(boolean)
,setFocused(boolean)
,setLongClickable(boolean)
,setSelected(boolean)
,
If an AccessibilityDelegateCompat
has been specified via calling
setAccessibilityDelegate(View, AccessibilityDelegateCompat)
, its
onInitializeAccessibilityNodeInfo(View, AccessibilityNodeInfoCompat)
method is responsible for handling this call.

in API level 26.1.0.
Call onPopulateAccessibilityEvent(AccessibilityEvent)
directly.
This method will be removed in a future release.
Called from 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
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
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
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.
Parameters | |
---|---|
v |
View |
delegate |
AccessibilityDelegateCompat : the object to which accessibility method calls should be
delegated |
See also:
setAccessibilityLiveRegion
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:
|
setActivated
void setActivated (View view, boolean activated)
This method was deprecated
in API level 26.1.0.
Use 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
void setAlpha (View view, float value)
This method was deprecated
in API level 26.1.0.
Use 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
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:
AUTOFILL_HINT_USERNAME
, AUTOFILL_HINT_PASSWORD
,
AUTOFILL_HINT_EMAIL_ADDRESS
,
AUTOFILL_HINT_NAME
,
AUTOFILL_HINT_PHONE
,
AUTOFILL_HINT_POSTAL_ADDRESS
, AUTOFILL_HINT_POSTAL_CODE
,
AUTOFILL_HINT_CREDIT_CARD_NUMBER
,
AUTOFILL_HINT_CREDIT_CARD_SECURITY_CODE
,
AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_DATE
,
AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_DAY
,
AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_MONTH
or
AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_YEAR
.
This method is only supported on API >= 26. On API 25 and below, it is a no-op
Parameters | |

such as the status bar and inset its content; that is, controlling whether
the default implementation of fitSystemWindows(Rect)
will be
executed. See that method for more details.
Parameters | |
---|---|
view |
View |
fitSystemWindows |
boolean |
setFocusedByDefault
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
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
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. |
setImportantForAutofill
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
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
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
IMPORTANT_FOR_AUTOFILL_YES_EXCLUDE_DESCENDANTS
.
NOTE: setting the mode as does IMPORTANT_FOR_AUTOFILL_NO
or
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
setKeyboardNavigationCluster
void setKeyboardNavigationCluster (View view, boolean isCluster)
Set whether view
is a root of a keyboard navigation cluster. Does nothing if
API < 26.
Parameters | |
---|---|

isCluster |
boolean : true to mark view as the root of a cluster, false
to unmark.
|

void setLabelFor (View view, int labeledId)
Sets the id of a view for which a given view serves as a label for accessibility purposes.
Parameters | |
---|---|
view |
View : The view on which to invoke the corresponding method. |
labeledId |
int : The labeled view id.
|
setLayerPaint
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 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:
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
LAYER_TYPE_NONE |
setLayerType
void setLayerType (View view, int layerType, Paint paint)
This method was deprecated
in API level 26.1.0.
Use setLayerType(int, Paint)
directly.
Specifies the type of layer backing this view. The layer can be
disabled
, software
or
hardware
.

setLayoutDirection
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
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.

startNestedScroll
boolean startNestedScroll (View view, int axes, int type)
Begin a nestable scroll operation along the given axes.
A view starting a nested scroll promises to abide by the following contract:
The view will call startNestedScroll upon initiating a scroll operation. In the case
of a touch scroll this corresponds to the initial ACTION_DOWN
.
In the case of touch scrolling the nested scroll will be terminated automatically in
the same manner as requestDisallowInterceptTouchEvent(boolean)
.
In the event of programmatic scrolling the caller must explicitly call
stopNestedScroll(View)
to indicate the end of the nested scroll.
If startNestedScroll
returns true, a cooperative parent was found.
If it returns false the caller may ignore the rest of this contract until the next scroll.
Calling startNestedScroll while a nested scroll is already in progress will return true.
At each incremental step of the scroll the caller should invoke
dispatchNestedPreScroll
once it has calculated the requested scrolling delta. If it returns true the nested scrolling
parent at least partially consumed the scroll and the caller should adjust the amount it
scrolls by.
After applying the remainder of the scroll delta the caller should invoke
dispatchNestedScroll
, passing
both the delta consumed and the delta unconsumed. A nested scrolling parent may treat
these values differently. See
onNestedScroll(View, int, int, int, int)
.
Parameters | |
---|---|
view |
View |
axes |
int : Flags consisting of a combination of SCROLL_AXIS_HORIZONTAL
and/or SCROLL_AXIS_VERTICAL . |
type |
int : the type of input which cause this scroll event |

---|---|
boolean |
true if a cooperative parent was found and nested scrolling has been enabled for the current gesture. |
startNestedScroll
boolean startNestedScroll (View view, int axes)
Begin a nestable scroll operation along the given axes.
This version of the method just calls startNestedScroll(View, int, int)
using
the touch input type.
