android - key listener is not working for layout -

-

i want add onkeylistener linear layout not working, here code. in advance.

 innerlayout.setonkeylistener(new onkeylistener() {                  @override                 public boolean onkey(view v, int arg1, keyevent e) {                     // todo auto-generated method stub                     if(e.getkeycode()==keyevent.action_down){                          toast.maketext(homescreen.this, "down key working", toast.length_long).show();                         innerlayout.setfocusable(true);                     }                     return true;                 }             });  }

as touch events passed child parent. if child consumes (returns true), stops; not passed parent. sure not consumed elsewhere? check this, true 1 action, false rest , super call:

@override public boolean onkeydown(int keycode, keyevent event) { super.onkeydown(keycode, event);         if (event.getaction() == keyevent.action_down) {         //toast here             return true;         }         **return false;**     }

also, found:
onkeylistener or onkeydown not work if children views take focus
onkeydown not being called on key press on view
case? hierarchy of layouts

i'm trying subclass qstyleditemdelegate remove focus rectangle in qcombobox . even though i'm calling base implementation of paint function , nothing else, result different. looks if parts of style-sheet influence bounding box of item taken consideration. class pstyleditemdelegate(qstyleditemdelegate): def __init__(self, *args, **kwds): super(pstyleditemdelegate, self).__init__(*args, **kwds) def paint(self, *args, **kwargs): qstyleditemdelegate.paint(*args, **kwargs) what have paint unmodified qstyleditemdelegate ? as suggested tried replacing pyside pyqt4 , works, appears bug. update pyside 1.1.2 1.2.1 result same. unfortunately switch breaks other parts of code, if there no other suggestions i'm going accept answer. edit bug tracked here
