NullPointerException이 SQLite 데이터베이스에 의해 간접적으로 호출 되었습니까?

Question

MyCursorAdapter.bindView를 호출하려고하면 안드로이드 애플리케이션이 작동을 멈 춥니 다. body.setText(cursor.getString(cursor.getColumnIndex(TasksDBAdapter.Key_BODY))); 다른 정보를 필요로

TextView title = (TextView) view.findViewById(R.id.title); 
    EditText body = (EditText) view.findViewById(R.id.body); 
    TextView created = (TextView) view.findViewById(R.id.created); 

    title.setText(cursor.getString(cursor.getColumnIndex(TasksDBAdapter.KEY_TITLE))); 
    title.setSelected(cursor.getInt(cursor.getColumnIndex(TasksDBAdapter.KEY_COMPLETED)) > 0); 
    body.setText(cursor.getString(cursor.getColumnIndex(TasksDBAdapter.KEY_BODY))); 
    created.setText(((Long)cursor.getLong(cursor.getColumnIndex(TasksDBAdapter.KEY_CREATED))).toString());

내 CursorAdapter에서의 Bindview 방법입니다 : 여기에 로그 캣 로그는?

UPDATE :

EditText body = (EditText) view.findViewById(R.id.body); 

가 null 것 같다? 여기에 위젯입니다 :

<EditText android:id="@+id/body" android:layout_below="@+id/body_txt" android:text="" android:layout_width="fill_parent" android:layout_height="wrap_content" android:minLines="10"></EditText> 

Answer 1

당신은 다른 뷰에서 참조를 얻을 필요가의 Bindview 방법에서보기 매개 변수입니다. 뷰는 전체 레이아웃이 아닌 행 레이아웃 일뿐입니다. 그 이유는 view.findViewById를 수행 할 때 Android가이 뷰에서이 ID를 알지 못하므로 null을 반환하기 때문입니다.
