Remarks

Dispatches an AccessibilityEvent to the View first and then to its children for adding their text content to the event. Note that the event text is populated in a separate dispatch path since we add to the event not only the text of the source but also the text of all its descendants. A typical implementation will call #onPopulateAccessibilityEvent(AccessibilityEvent) on the this view and then call the #dispatchPopulateAccessibilityEvent(AccessibilityEvent) on each child. Override this method if custom population of the event text content is required.

If an AccessibilityDelegate has been specified via calling #setAccessibilityDelegate(AccessibilityDelegate) its AccessibilityDelegate#dispatchPopulateAccessibilityEvent(View, AccessibilityEvent) is responsible for handling this call.

If this view sets #isAccessibilityDataSensitive() then this view should only append sensitive information to an event that also sets AccessibilityEvent#isAccessibilityDataSensitive().

<em>Note:</em> Accessibility events of certain types are not dispatched for populating the event text via this method. For details refer to AccessibilityEvent.
