public static interface View.OnKeyListener
Key presses in software keyboards will generally NOT trigger this method, although some may elect to do so in some situations. Do not assume a software input method has to be key-based; even if it is, it may use key presses in a different way than you expect, so there is no way to reliably catch soft input key presses.
v- The view the key has been dispatched to.
keyCode- The code for the physical key that was pressed
event- The KeyEvent object containing full information about the event.
