Constants

CONTENT_CHANGE_TYPE_CONTENT_DESCRIPTION

static val CONTENT_CHANGE_TYPE_CONTENT_DESCRIPTION: Int

Change type for TYPE_WINDOW_CONTENT_CHANGED event: The node's content description changed.

Value: 0x00000004

CONTENT_CHANGE_TYPE_PANE_APPEARED

static val CONTENT_CHANGE_TYPE_PANE_APPEARED: Int

Change type for AccessibilityEvent#TYPE_WINDOW_STATE_CHANGED event: The node has a pane title, and either just appeared or just was assigned a title when it had none before.

Value: 0x00000010

CONTENT_CHANGE_TYPE_PANE_DISAPPEARED

static val CONTENT_CHANGE_TYPE_PANE_DISAPPEARED: Int

Change type for AccessibilityEvent#TYPE_WINDOW_STATE_CHANGED event: Can mean one of two slightly different things. The primary meaning is that the node has a pane title, and was removed from the node hierarchy. It can also be sent if the pane title is set to null after it contained a title. No source will be returned if the node is no longer on the screen. To make the change more clear for the user, the first entry in AccessibilityRecord#getText() can return the value that would have been returned by getSource().getPaneTitle().

Value: 0x00000020

CONTENT_CHANGE_TYPE_PANE_TITLE

static val CONTENT_CHANGE_TYPE_PANE_TITLE: Int

Change type for AccessibilityEvent#TYPE_WINDOW_STATE_CHANGED event: The node's pane title changed.

Value: 0x00000008

CONTENT_CHANGE_TYPE_STATE_DESCRIPTION

static val CONTENT_CHANGE_TYPE_STATE_DESCRIPTION: Int

Change type for AccessibilityEvent#TYPE_WINDOW_CONTENT_CHANGED event: state description of the node as returned by AccessibilityNodeInfo#getStateDescription was changed.

Value: 0x00000040

CONTENT_CHANGE_TYPE_SUBTREE

static val CONTENT_CHANGE_TYPE_SUBTREE: Int

Change type for TYPE_WINDOW_CONTENT_CHANGED event: A node in the subtree rooted at the source node was added or removed.

Value: 0x00000001

CONTENT_CHANGE_TYPE_TEXT

static val CONTENT_CHANGE_TYPE_TEXT: Int

Change type for TYPE_WINDOW_CONTENT_CHANGED event: The node's text changed.

Value: 0x00000002

CONTENT_CHANGE_TYPE_UNDEFINED

static val CONTENT_CHANGE_TYPE_UNDEFINED: Int

Change type for TYPE_WINDOW_CONTENT_CHANGED event: The type of change is not defined.

Value: 0x00000000

TYPES_ALL_MASK

static val TYPES_ALL_MASK: Int

Mask for AccessibilityEvent all types.

Value: 0xFFFFFFFF
