android - Reset variable on spinner exit by back button press -

i update variable when user decides exit app when particular spinner displayed.

i tried doing overriding onbackpressed, not called when user exits spinner via key though spinner killed.

this not work:

imageshareopts.setonkeylistener(new onkeylistener(){     public boolean onkey(view v, int keycode, keyevent event) {         if (keycode == keyevent.keycode_back) {             log.i("test12", "back key listener in spinner");             spinnernotdefault = false;             imageshareopts.setselection(-1);            }         return false;     }                        }); 

i have tried overide onkeydown() no called:

@override public boolean onkeydown(int keycode, keyevent event) {     // todo auto-generated method stub     if (keycode == keyevent.keycode_back) {         // here implements code.         spinnernotdefault = false;         log.i("test12", "onkeydown spinnernotdefault:"+spinnernotdefault);         log.d(tag, "keycode_back");     }     return super.onkeydown(keycode, event); } 

thanks..
