i have gone callbacks, there way menuitem of parent activity in fragment?

like: getactvity().getactionbar().getmenuitem(0);

quoting docs

if want update

your fragments can contribute menu items activity's options menu (and, consequently, action bar) implementing oncreateoptionsmenu(). in order method receive calls, however, must call sethasoptionsmenu() during oncreate(), indicate fragment add items options menu (otherwise, fragment not receive call oncreateoptionsmenu()).

so have in oncreate

 sethasoptionsmenu(true); 

override oncreateoptionsmenu()

@override public void oncreateoptionsmenu(menu menu, menuinflater inflater) { // todo add menu entries here super.oncreateoptionsmenu(menu, inflater); }
