AccessibilityNodeInfoCompat.AccessibilityActionCompat

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.

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.

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.

const val ACTION_CLEAR_SELECTION: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

Action that deselects the node.

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.

const val ACTION_COLLAPSE: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

Action to collapse an expandable node.

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.

const val ACTION_COPY: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

Action to copy the current selection to the clipboard.

const val ACTION_CUT: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

const val ACTION_DRAG_CANCEL: AccessibilityNodeInfoCompat.AccessibilityActionCompat

Action to cancel a drag.

This action is added to the source that started a drag with ACTION_DRAG_START.

const val ACTION_DRAG_DROP: AccessibilityNodeInfoCompat.AccessibilityActionCompat

Action to trigger a drop of the content being dragged.

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.

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.

const val ACTION_EXPAND: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

Action to expand an expandable node.

const val ACTION_FOCUS: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

Action that gives input focus to the node.

The focus request sends an event of TYPE_VIEW_FOCUSED if successful. In the View system, this is handled by requestFocus.

The node that is focused should return true for isFocused.

const val ACTION_HIDE_TOOLTIP: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

Action to hide a tooltip. A node should expose this action only for views that are currently showing a tooltip.

const val ACTION_IME_ENTER: AccessibilityNodeInfoCompat.AccessibilityActionCompat

Action to send an ime actionId which is from actionId. This ime actionId sets by setImeActionLabel, or it would be IME_ACTION_UNSPECIFIED if no specific actionId has set. A node should expose this action only for views that are currently with input focus and editable.

const val ACTION_LONG_CLICK: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

Action that long clicks on the node.

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

isLongClickable should return true if this action is available.

const val ACTION_MOVE_WINDOW: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

Action to move a window to a new location.

Arguments:ACTION_ARGUMENT_MOVE_WINDOW_XACTION_ARGUMENT_MOVE_WINDOW_Y

const val ACTION_NEXT_AT_MOVEMENT_GRANULARITY: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

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

          

            
  Bundle arguments = new Bundle();
  arguments.putInt(AccessibilityNodeInfoCompat.ACTION_ARGUMENT_MOVEMENT_GRANULARITY_INT,
          AccessibilityNodeInfoCompat.MOVEMENT_GRANULARITY_CHARACTER);
  arguments.putBoolean(
          AccessibilityNodeInfoCompat.ACTION_ARGUMENT_EXTEND_SELECTION_BOOLEAN, false);
  info.performAction(
          AccessibilityActionCompat.ACTION_NEXT_AT_MOVEMENT_GRANULARITY.getId(),
          arguments);
          

        

const val ACTION_NEXT_HTML_ELEMENT: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

Action to move to the next HTML element of a given type. For example, move to the BUTTON, INPUT, TABLE, etc.

Arguments:AccessibilityNodeInfoCompat.ACTION_ARGUMENT_HTML_ELEMENT_STRINGExample:

          

            
  Bundle arguments = new Bundle();
  arguments.putString(
          AccessibilityNodeInfoCompat.ACTION_ARGUMENT_HTML_ELEMENT_STRING, "BUTTON");
  info.performAction(
          AccessibilityActionCompat.ACTION_NEXT_HTML_ELEMENT.getId(), arguments);
          

        

const val ACTION_PAGE_DOWN: AccessibilityNodeInfoCompat.AccessibilityActionCompat

const val ACTION_PAGE_UP: AccessibilityNodeInfoCompat.AccessibilityActionCompat

Action to move to the page above.

const val ACTION_PASTE: AccessibilityNodeInfoCompat.AccessibilityActionCompat!

Action to paste the current clipboard content.

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.

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.

          AccessibilityNodeInfoCompat.MOVEMENT_GRANULARITY_CHARACTER);
  arguments.putBoolean(
          AccessibilityNodeInfoCompat.ACTION_ARGUMENT_EXTEND_SELECTION_BOOLEAN, false);
  info.performAction(
