Answer 1

왜 R.layout.main_fragment이 그 안에 두 조각이 있는가? Fragment 안에 Fragment을 넣을 수는 없습니다 ... Activity 안에 있어야합니다. 대신 artist_fragment.xml을 부풀려 야합니까?

Answer 2

랩 (나는 무슨 일이 일어나고 생각입니다) 오리엔테이션이나 활동 변화에 대한 모든 것을 다시 시도하는 프레임 워크를 방지 할 수

if(savesInstanceState == null) { 
    // your code here 
} 

이있는 onCreate 방법의 코드. (대부분의 경우) 모든 활동에서 이것을 사용해야하므로 대부분의 사람들이 기대하는 것처럼 프레임 워크가 작동 할 수 있습니다.
