yes overriding onprepareoptionsmenu method : prepare screen's standard options menu displayed. called right before menu shown, every time shown. can use method efficiently enable/disable items or otherwise dynamically modify contents. make action item visible or gone below(just sample code).

@override public boolean onprepareoptionsmenu(menu menu) {      menuitem menuitemvadd = menu.finditem(r.id.action_vadd);      if (isshowvisualadd1) {             menuitemvadd.setvisible(true);      } else {             menuitemvadd.setvisible(false);      }      return super.onprepareoptionsmenu(menu); }
