Question

Flagment 의 onCreateView  에서 container 이 null 이나오는 이유가 뭐가있을까요?

xml 에서 프래그먼트를 포함시키고 디버깅해보면

onCreateView  에서 container 이 null 이나와서 죽습니다

이경우 어디를 살펴봐야될까요?

      // We have different layouts, and in one of them this
      // fragment's containing frame doesn't exist.  The fragment
      // may still be created from its saved state, but there is
      // no reason to try to create its view hierarchy because it

   }

   mCtx = getActivity();

   init();
   View v = init();

   return v;
