The target View has been invalidated, or has had a drawing property changed that requires the hierarchy to re-render. This method is called by the View hierarchy to signal ancestors that a View either needs to re-record its drawing commands, or drawing properties have changed. This is how Views schedule a drawing traversal. This signal is generally only dispatched for attached Views, since only they need to draw. If you override this method you must call through to the superclass implementation.
