edittext.setOnKeyListener(new OnKeyListener() {

        @Override
        public boolean onKey(View v , int keyCode , KeyEvent event) {

            // TODO Auto-generated method stub
            if (keyCode == event.KEYCODE_A) {
                // Do what you want here
            }

            return false;
        }
    });
