class 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. Each standard action is associated with a resource id, e.g. accessibilityActionScrollUp. Note that actions were formerly associated with static constants 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 setImportantForAccessibility with IMPORTANT_FOR_ACCESSIBILITY_YES to ensure an android.accessibilityservice.AccessibilityService can discover the set of supported actions.

Constants

ACTION_ACCESSIBILITY_FOCUS

Added in 1.1.0

const val ACTION_ACCESSIBILITY_FOCUS: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

Action that gives accessibility focus to the node.

The UI element that implements this should send a TYPE_VIEW_ACCESSIBILITY_FOCUSED event if successful. The node that is focused should return true for isAccessibilityFocused.

This is intended to be used by screen readers to assist with user navigation. Apps changing focus can confuse screen readers, so the resulting behavior can vary by device and screen reader version.

This is distinct from ACTION_FOCUS, which refers to system focus. System focus is typically used to convey targets for keyboard navigation.

ACTION_CLEAR_ACCESSIBILITY_FOCUS

Added in 1.1.0

const val ACTION_CLEAR_ACCESSIBILITY_FOCUS: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

Action that clears accessibility focus of the node.

The UI element that implements this should send a TYPE_VIEW_ACCESSIBILITY_FOCUS_CLEARED event if successful. The node that is cleared should return false for isAccessibilityFocused.

ACTION_CLEAR_FOCUS

Added in 1.1.0

const val ACTION_CLEAR_FOCUS: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

Action that clears input focus of the node.

The node that is cleared should return false for isFocused.

Added in 1.1.0

const val ACTION_CLEAR_SELECTION: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

Action that deselects the node.

ACTION_CLICK

Added in 1.1.0

const val ACTION_CLICK: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

Action that clicks on the node info.

The UI element that implements this should send a TYPE_VIEW_CLICKED event. In the View system, the default handling of this action when performed by a service is to call performClick, and setting a setOnClickListener automatically adds this action.

isClickable should return true if this action is available.

ACTION_COLLAPSE

Added in 1.1.0

const val ACTION_COLLAPSE: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

Action to collapse an expandable node.

ACTION_CONTEXT_CLICK

Added in 1.1.0

const val ACTION_CONTEXT_CLICK: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

Action that context clicks the node.

The UI element that implements this should send a TYPE_VIEW_CONTEXT_CLICKED event. In the View system, the default handling of this action when performed by a service is to call performContextClick, and setting a setOnContextClickListener automatically adds this action.

A context click usually occurs from a mouse pointer right-click or a stylus button press.

isContextClickable should return true if this action is available.

ACTION_COPY

Added in 1.1.0

const val ACTION_COPY: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

Action to copy the current selection to the clipboard.

ACTION_CUT

Added in 1.1.0

This action is added to potential drop targets if the source started a drag with ACTION_DRAG_START. In View, these targets are Views that accepted ACTION_DRAG_STARTED and have an View.OnDragListener.

See also
CONTENT_CHANGE_TYPE_DRAG_DROPPED

ACTION_DRAG_START

Added in 1.9.0

const val ACTION_DRAG_START: AccessibilityNodeInfoCompat.AccessibilityActionCompat

Action to start a drag.

This action initiates a drag &drop within the system. The source's dragged content is prepared before the drag begins. In View, this action should prepare the arguments to startDragAndDrop} and then call the method. The equivalent should be performed for other UI toolkits.

See also
CONTENT_CHANGE_TYPE_DRAG_STARTED

ACTION_EXPAND

Added in 1.1.0

const val ACTION_EXPAND: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

Action to expand an expandable node.

ACTION_FOCUS

Added in 1.1.0

const val ACTION_FOCUS: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

ACTION_PASTE

Added in 1.1.0

const val ACTION_PASTE: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

Action to paste the current clipboard content.

ACTION_PRESS_AND_HOLD

Added in 1.5.0

const 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

Added in 1.1.0

const 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.

Arguments:AccessibilityNodeInfoCompat.ACTION_ARGUMENT_MOVEMENT_GRANULARITY_INT, AccessibilityNodeInfoCompat.ACTION_ARGUMENT_EXTEND_SELECTION_BOOLEANExample: Move to the next character and do not extend selection.

          

            
  Bundle arguments = new Bundle();
  arguments.putInt(AccessibilityNodeInfoCompat.ACTION_ARGUMENT_MOVEMENT_GRANULARITY_INT,
          AccessibilityNodeInfoCompat.MOVEMENT_GRANULARITY_CHARACTER);
