Question

은 (편집)

는 TabClubActivity.java :

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    Log.e("First", "First"); 

    setContentView(R.layout.tab_club_layout); ---> 140th error line in logcat 

    Log.e("Second", "Second"); 

    MapFragment fragment = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)); 
    map = fragment.getMap(); 
    fragment.onResume(); 

    ................ 

    } 

당신은 아래에서 보는 바와 같이 로그가 인쇄 중입니다 "첫 번째"로그 문과 "두 번째"로그 문을 인쇄하지 않습니다.

레이아웃에 문제가있는 것은 확실합니다.

내가 TabClubActivity.That 내부 어댑터 클래스를 사용하고 구글 맵 라이브러리 버전 29

를 사용하여 나는 내부 클래스로서 어댑터 클래스를 사용하고 의미하고있다.

Eclipse 버전 21을 사용하고 있습니다. 많은 SO 게시물을 시도했지만 문제를 해결할 수 없습니다.

Answer 1

내가 안드로이드 스튜디오와 노력 이클립스 tool.Then에서이 문제를 해결할 수없는 몇 있겠다고을 보내고 .

지도가 잘 작동합니다. 문제는 스튜디오에서만 해결되었습니다. Google지도 라이브러리 문제가 여러 번 나에게 발생했습니다.하지만 스튜디오로 이전하면 코드가 정상적으로 작동합니다.

이클립스 도구 및 sdk로 변경된 새로운 OS의 변경으로 인해 오류가 발생했습니다. Google지도 라이브러리 문제 일 수 있습니다.

Answer 2

활동이 android.app.fragment으로 가져 오나요?

그렇다면 android.v4.app.fragment으로 시도해보세요.

은 나중에, 당신은 에서 getSupportFragmentManager를 사용할 필요하지 getFragment 수 있습니다.

Answer 3

변화 getFragmentManager()getSupportFragmentManager() .This 예외로 수입과 imports android.app.Fragment .Replace을 사용하고 있기 때문에 android.v4.app.Fragment

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    Log.e("First", "First"); 

    setContentView(R.layout.tab_club_layout); ---> 140th error line in logcat 

    Log.e("Second", "Second"); 

    MapFragment fragment = ((MapFragment)getSupportFragmentManager().findFragmentById(R.id.map)); 
    map = fragment.getMap(); 
    fragment.onResume(); 

    ................ 

    }
