# AccessibilityNodeInfo.AccessibilityAction Added in[API level 21](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) # AccessibilityAction *** ** * ** *** Kotlin\|[Java](https://developer.android.com/reference/android/view/accessibility/AccessibilityNodeInfo.AccessibilityAction "View this page in Java") ``` class AccessibilityAction : Parcelable ``` |---|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | [kotlin.Any](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-any/index.html) || | ↳ | [android.view.accessibility.AccessibilityNodeInfo.AccessibilityAction](https://developer.android.com/reference/kotlin/android/view/accessibility/AccessibilityNodeInfo.AccessibilityAction#) | A class defining an action that can be performed on an[AccessibilityNodeInfo](https://developer.android.com/reference/kotlin/android/view/accessibility/AccessibilityNodeInfo). Each action has a mandatory unique id and optional data. There are three categories of actions: - **Standard actions** - These are actions that are reported and handled by the standard UI widgets in the platform. For each standard action there is a static constant defined in this class, e.g.[ACTION_FOCUS](https://developer.android.com/reference/kotlin/android/view/accessibility/AccessibilityNodeInfo.AccessibilityAction#ACTION_FOCUS:android.view.accessibility.AccessibilityNodeInfo.AccessibilityAction). These actions will have`null`labels. - **Custom actions action**- These are actions that are reported and handled by custom widgets. i.e. ones that are not part of the UI toolkit. For example, an application may define a custom action for clearing the user history. - **Overridden standard actions** - These are actions that override standard actions to customize them. For example, an app may add a label to the standard[ACTION_CLICK](https://developer.android.com/reference/kotlin/android/view/accessibility/AccessibilityNodeInfo.AccessibilityAction#ACTION_CLICK:android.view.accessibility.AccessibilityNodeInfo.AccessibilityAction)action to indicate to the user that this action clears browsing history.
Actions are typically added to an[AccessibilityNodeInfo](https://developer.android.com/reference/kotlin/android/view/accessibility/AccessibilityNodeInfo)by using[AccessibilityNodeInfo.addAction(AccessibilityAction)](https://developer.android.com/reference/kotlin/android/view/accessibility/AccessibilityNodeInfo#addAction(android.view.accessibility.AccessibilityNodeInfo.AccessibilityAction))within[View.onInitializeAccessibilityNodeInfo(AccessibilityNodeInfo)](https://developer.android.com/reference/kotlin/android/view/View.html#onInitializeAccessibilityNodeInfo(android.view.accessibility.AccessibilityNodeInfo))and are performed within[View.performAccessibilityAction(int, Bundle)](https://developer.android.com/reference/kotlin/android/view/View.html#performAccessibilityAction(kotlin.Int,%20android.os.Bundle)).
**Note:** Views which support these actions should invoke[View.setImportantForAccessibility(int)](https://developer.android.com/reference/kotlin/android/view/View.html#setImportantForAccessibility(kotlin.Int))with[View.IMPORTANT_FOR_ACCESSIBILITY_YES](https://developer.android.com/reference/kotlin/android/view/View.html#IMPORTANT_FOR_ACCESSIBILITY_YES:kotlin.Int)to ensure an[AccessibilityService](https://developer.android.com/reference/kotlin/android/accessibilityservice/AccessibilityService.html#)can discover the set of supported actions.

**Note:** Use androidx.core.view.ViewCompat#addAccessibilityAction(View, \* CharSequence, AccessibilityViewCommand) to register an action directly on the view.

Flag for use with[writeToParcel](https://developer.android.com/reference/kotlin/android/os/Parcelable.html#writeToParcel(android.os.Parcel,%20kotlin.Int)): the object being written is a return value, that is the result of a function such as "`Parcelable someFunction()`", "`void someFunction(out Parcelable)`", or "`void someFunction(inout Parcelable)`". Some implementations may want to release resources at this point.

| ## Public constructors ### AccessibilityAction Added in[API level 21](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` AccessibilityAction(     actionId: Int,     label: CharSequence?) ``` Creates a new AccessibilityAction. For adding a standard action without a specific label, use the static constants. You can also override the description for one the standard actions. Below is an example how to override the standard click action by adding a custom label: ```kotlin AccessibilityAction action = new AccessibilityAction( AccessibilityAction.ACTION_CLICK.getId(), getLocalizedLabel()); node.addAction(action); ```
| Parameters || |------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `actionId` | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html):The id for this action. This should either be one of the standard actions or a specific action for your app. In that case it is required to use a resource identifier. | | `label` | [CharSequence](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-char-sequence/index.html)?:The label for the new AccessibilityAction. This value may be`null`. | ## Public methods ### describeContents Added in[API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` fun describeContents(): Int ``` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of[writeToParcel(android.os.Parcel,int)](https://developer.android.com/reference/kotlin/android/os/Parcelable.html#writeToParcel(android.os.Parcel,%20kotlin.Int)), the return value of this method must include the[CONTENTS_FILE_DESCRIPTOR](https://developer.android.com/reference/kotlin/android/os/Parcelable.html#CONTENTS_FILE_DESCRIPTOR:kotlin.Int)bit. | Return || |----------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html) | a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either`0`or[android.os.Parcelable#CONTENTS_FILE_DESCRIPTOR](https://developer.android.com/reference/kotlin/android/os/Parcelable.html#CONTENTS_FILE_DESCRIPTOR:kotlin.Int) | ### equals Added in[API level 21](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` fun equals(other: Any?): Boolean ``` Indicates whether some other object is "equal to" this one. The`equals`method implements an equivalence relation on non-null object references: - It is*reflexive* : for any non-null reference value`x`,`x.equals(x)`should return`true`. - It is*symmetric* : for any non-null reference values`x`and`y`,`x.equals(y)`should return`true`if and only if`y.equals(x)`returns`true`. - It is*transitive* : for any non-null reference values`x`,`y`, and`z`, if`x.equals(y)`returns`true`and`y.equals(z)`returns`true`, then`x.equals(z)`should return`true`. - It is*consistent* : for any non-null reference values`x`and`y`, multiple invocations of`x.equals(y)`consistently return`true`or consistently return`false`, provided no information used in`equals`comparisons on the objects is modified. - For any non-null reference value`x`,`x.equals(null)`should return`false`.

The UI element that implements this should send a[AccessibilityEvent.TYPE_VIEW_SCROLLED](https://developer.android.com/reference/kotlin/android/view/accessibility/AccessibilityEvent#TYPE_VIEW_SCROLLED:kotlin.Int)event. ### ACTION_PAGE_LEFT Added in[API level 29](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` static val ACTION_PAGE_LEFT: AccessibilityNodeInfo.AccessibilityAction! ``` Action to move to the page left. The UI element that implements this should send a[AccessibilityEvent.TYPE_VIEW_SCROLLED](https://developer.android.com/reference/kotlin/android/view/accessibility/AccessibilityEvent#TYPE_VIEW_SCROLLED:kotlin.Int)event. ### ACTION_PAGE_RIGHT Added in[API level 29](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` static val ACTION_PAGE_RIGHT: AccessibilityNodeInfo.AccessibilityAction! ``` Action to move to the page right. The UI element that implements this should send a[AccessibilityEvent.TYPE_VIEW_SCROLLED](https://developer.android.com/reference/kotlin/android/view/accessibility/AccessibilityEvent#TYPE_VIEW_SCROLLED:kotlin.Int)event. ### ACTION_PAGE_UP Added in[API level 29](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` static val ACTION_PAGE_UP: AccessibilityNodeInfo.AccessibilityAction! ``` Action to move to the page above. The UI element that implements this should send a[AccessibilityEvent.TYPE_VIEW_SCROLLED](https://developer.android.com/reference/kotlin/android/view/accessibility/AccessibilityEvent#TYPE_VIEW_SCROLLED:kotlin.Int)event. ### ACTION_PASTE Added in[API level 21](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` static val ACTION_PASTE: AccessibilityNodeInfo.AccessibilityAction! ``` Action to paste the current clipboard content. ### ACTION_PRESS_AND_HOLD Added in[API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` static val ACTION_PRESS_AND_HOLD: AccessibilityNodeInfo.AccessibilityAction ``` Action that presses and holds a node. This action is for nodes that have distinct behavior that depends on how long a press is held. Nodes having a single action for long press should use[ACTION_LONG_CLICK](https://developer.android.com/reference/kotlin/android/view/accessibility/AccessibilityNodeInfo.AccessibilityAction#ACTION_LONG_CLICK:android.view.accessibility.AccessibilityNodeInfo.AccessibilityAction)instead of this action, and nodes should not expose both actions. When calling`performAction(ACTION_PRESS_AND_HOLD, bundle`, use[ACTION_ARGUMENT_PRESS_AND_HOLD_DURATION_MILLIS_INT](https://developer.android.com/reference/kotlin/android/view/accessibility/AccessibilityNodeInfo#ACTION_ARGUMENT_PRESS_AND_HOLD_DURATION_MILLIS_INT:kotlin.String)to specify how long the node is pressed. The first time an accessibility service performs ACTION_PRES_AND_HOLD on a node, it must specify 0 as ACTION_ARGUMENT_PRESS_AND_HOLD, so the application is notified that the held state has started. To ensure reasonable behavior, the values must be increased incrementally and may not exceed 10,000. UIs requested to hold for times outside of this range should ignore the action. The total time the element is held could be specified by an accessibility user up-front, or may depend on what happens on the UI as the user continues to request the hold. **Note:**The time between dispatching the action and it arriving in the UI process is not guaranteed. It is possible on a busy system for the time to expire unexpectedly. For the case of holding down a key for a repeating action, a delayed arrival should be benign. Please do not use this sort of action in cases where such delays will lead to unexpected UI behavior.
### ACTION_PREVIOUS_AT_MOVEMENT_GRANULARITY Added in[API level 21](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` static val ACTION_PREVIOUS_AT_MOVEMENT_GRANULARITY: AccessibilityNodeInfo.AccessibilityAction! ``` Action that requests to go to the previous entity in this node's text at a given movement granularity.

The UI element that implements this should send a[AccessibilityEvent.TYPE_VIEW_SCROLLED](https://developer.android.com/reference/kotlin/android/view/accessibility/AccessibilityEvent#TYPE_VIEW_SCROLLED:kotlin.Int)event. Depending on the orientation, this element should also add the relevant directional scroll actions of[ACTION_SCROLL_LEFT](https://developer.android.com/reference/kotlin/android/view/accessibility/AccessibilityNodeInfo.AccessibilityAction#ACTION_SCROLL_LEFT:android.view.accessibility.AccessibilityNodeInfo.AccessibilityAction),[ACTION_SCROLL_RIGHT](https://developer.android.com/reference/kotlin/android/view/accessibility/AccessibilityNodeInfo.AccessibilityAction#ACTION_SCROLL_RIGHT:android.view.accessibility.AccessibilityNodeInfo.AccessibilityAction),[ACTION_SCROLL_UP](https://developer.android.com/reference/kotlin/android/view/accessibility/AccessibilityNodeInfo.AccessibilityAction#ACTION_SCROLL_UP:android.view.accessibility.AccessibilityNodeInfo.AccessibilityAction), and[ACTION_SCROLL_DOWN](https://developer.android.com/reference/kotlin/android/view/accessibility/AccessibilityNodeInfo.AccessibilityAction#ACTION_SCROLL_DOWN:android.view.accessibility.AccessibilityNodeInfo.AccessibilityAction). If the scrolling brings the next or previous element into view as the center element, such as in a ViewPager2, use[ACTION_PAGE_DOWN](https://developer.android.com/reference/kotlin/android/view/accessibility/AccessibilityNodeInfo.AccessibilityAction#ACTION_PAGE_DOWN:android.view.accessibility.AccessibilityNodeInfo.AccessibilityAction)and the other page actions instead of the directional actions. Example: a scrolling UI of horizontal orientation with a backward scroll action should also add the scroll left/right action (LTR/RTL): ```kotlin onInitializeAccessibilityNodeInfo(AccessibilityNodeInfo info) { super.onInitializeAccessibilityNodeInfo(info); if (canScrollBackward) { info.addAction(ACTION_SCROLL_FORWARD); if (leftToRight) { info.addAction(ACTION_SCROLL_LEFT); } else { info.addAction(ACTION_SCROLL_RIGHT); } } } performAccessibilityAction(int action, Bundle bundle) { if (action == ACTION_SCROLL_BACKWARD) { scrollBackward(); } else if (action == ACTION_SCROLL_LEFT) { if (!isRTL()){ scrollBackward(); } } else if (action == ACTION_SCROLL_RIGHT) { if (isRTL()){ scrollBackward(); } } } scrollBackward() { ... if (mAccessibilityManager.isEnabled()) { event = new AccessibilityEvent(AccessibilityEvent.TYPE_VIEW_SCROLLED); event.setScrollDeltaX(dx); event.setScrollDeltaY(dy); event.setMaxScrollX(maxDx); event.setMaxScrollY(maxDY); sendAccessibilityEventUnchecked(event); } } ```
