를 호출 곳에서 내 주요 활동 누를 때 내 방식에 따라 당신이`MapFragment`를 제거해야 onDestroyView()

@Override

     try{ 
      MapFragment fragment = ((MapFragment) getFragmentManager().findFragmentById(R.id.fragment1); 
      FragmentTransaction ft = getActivity().getFragmentManager().beginTransaction(); 
      ft.remove(fragment); 
      ft.commit(); 
     }catch(Exception e){ 
     } 
     super.onDestroyView(); 
    }
