AccessibilityActionCompat

Kotlin |Java

open class AccessibilityActionCompat

kotlin.Any
↳	androidx.core.view.accessibility.AccessibilityNodeInfoCompat.AccessibilityActionCompat

A class defining an action that can be performed on an AccessibilityNodeInfo. Each action has a unique id and a label.

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. 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.
• Overriden 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 action to indicate to the user that this action clears browsing history.

Note: Views which support these actions should invoke View#setImportantForAccessibility(int) with View#IMPORTANT_FOR_ACCESSIBILITY_YES to ensure an android.accessibilityservice.AccessibilityService can discover the set of supported actions.

ACTION_PASTE

static val ACTION_PASTE: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

Action to paste the current clipboard content.

ACTION_PRESS_AND_HOLD

@NonNull static val ACTION_PRESS_AND_HOLD: AccessibilityNodeInfoCompat.AccessibilityActionCompat

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 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 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

static val ACTION_PREVIOUS_AT_MOVEMENT_GRANULARITY: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

Action that requests to go to the previous entity in this node's text at a given movement granularity. For example, move to the next character, word, etc.

Example: Move to the next character and do not extend selection.
