android - close fullscreen of Youtube Player on back button inside fragment -

i using master/detail layout in tablet, on left few buttons open several fragments, 1 of fragments contains youtube player.

the problem,

when youtube player full screen, , press button, activity onbackpressed called, , whole activity closed.

what have tried,

1- added on keylistener parent fragment (which contains youtube fragment) , handle when click on button, listener called if player not fullscreen, otherwise not called,

rootview.setfocusableintouchmode(true);         rootview.requestfocus();         rootview.setonkeylistener(new view.onkeylistener() {             @override             public boolean onkey(view v, int keycode, keyevent event) {                 if (keycode == keyevent.keycode_back && event.getaction() == keyevent.action_up) {                     try {                         // close full screen                         return true;                     } catch (exception e) {                         ahhexceptionhandler.handleexception(e);                     }                 }                 return false;             }         }); 

2- added onkeylistener youtubefragment view check if full screen close full screen mode

youtubefragment.getview().setfocusableintouchmode(true); youtubefragment.getview().requestfocus();     youtubefragment.getview().setonkeylistener(new view.onkeylistener() {                                                 @override                                                 public boolean onkey(view v, int keycode, keyevent event) {                                                     if (keycode == keyevent.keycode_back && event.getaction() == keyevent.action_up) {                                                         try {                                                             youtubeplayer.setfullscreen(false);                                                             return true;                                                         } catch (exception e) {                                                             ahhexceptionhandler.handleexception(e);                                                         }                                                     }                                                     return false;                                                 }                                             }); 

and not called in cases.

i need handle hardware button while youtube player in fullscreen, fullscreen mode closed , application in previous state.

thanks.

edit 1: - want handle inside fragment, instead of handling in parent activity, handling inside parent activity, don't solution.

you can overwrite onbackpressed() in activity , in case player fullscreen can handle here , call not super.onbackpressed().

if it's not fullscreen call super.onbackpressed().
