이 코드는 ExpandableListView와 관련이 있습니다. 따라서, 여기 의심되는 활동과 레이아웃 첨부 :

public class StudyHalls extends ExpanableListActivity { 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    Log.d(TAG, "on create"); 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.halls); 
      ... 
    } 
    ... 
}

halls.xml을 CTRL + F12가 방향을 변경 앱은 아직 그렇지 않으면에서 다음 태그를 언급 충돌하는 경우 볼 수

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:orientation="vertical" > 

<ExpandableListView 
    android:id="@id/android:list" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
/> 

</LinearLayout>

thx,'android : configChanges'는 작동하지만 'orientation'의 'o'는 대문자가 아니어야합니다. – manuzhang

@manuzhang : 자본 자체입니다. configChanges –

을 언급하면 기본 옵션이됩니다. 오류. 그것을 밖으로 시도하십시오 – manuzhang

onRestoreInstaceState() 델리게이트를 사용하고있는 것으로 보입니다. 이 작품은 기본보기에서만 유용합니다. 위와 같은 사용자 정의보기의 경우 manifest의 activity tag에 android:configChanges="orientation"을 사용하고 onRestoreInstaceState()을 제거하십시오.
