AccessibilityRecord

open class AccessibilityRecord
kotlin.Any
   ↳ android.view.accessibility.AccessibilityRecord

Represents a record in an AccessibilityEvent and contains information about state change of its source android.view.View. When a view fires an accessibility event it requests from its parent to dispatch the constructed event. The parent may optionally append a record for itself for providing more context to android.accessibilityservice.AccessibilityServices. Hence, accessibility services can facilitate additional accessibility records to enhance feedback.

Once the accessibility event containing a record is dispatched the record is made immutable and calling a state mutation method generates an error.

Note: Not all properties are applicable to all accessibility event types. For detailed information please refer to AccessibilityEvent.
