Parameters

keyCode: Keycode

The value in event.getKeyCode().

e: KeyEvent

Description of the key event.

Boolean

If you handled the event, return true. If you want to allow the event to be handled by the next receiver, return false.

Remarks

Handle a key event before it is processed by any input method associated with the view hierarchy. This can be used to intercept key events in special situations before the IME consumes them; a typical example would be handling the BACK key to update the application's UI instead of allowing the IME to see it and close itself.
