어제까지 잘 되던 거니까.. 다른 문제는 없으리라고 보는데요.

오늘 갑자기 아래 코드에서 넘어가질 않습니다.

고수님들 부탁드립니다.

 

     @Override
    protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.timeline);
  // Find views by id
  mListTimeLine = (ListView) findViewById(R.id.listTimeLine);
  // Initialize database
  mHelper = new DatabaseOpenHelper(this);
  mDb = mHelper.getReadableDatabase();
  // Get data
  c = mDb.query(DatabaseOpenHelper.TABLE, null, null, null, null, null, 
   DatabaseOpenHelper.C_CREATED_AT + " DESC");
  startManagingCursor(c);
  mAdapter = new TimelineAdapter(this, c);
  mListTimeLine.setAdapter(mAdapter);           <----------------    여기서 에러가 걸립니다. 
  mListTimeLine.setOnItemClickListener(list_click);
    }

에러 로그는 아래에 있습니다.

 mListTimeLine.setAdapter(mAdapter);   에서 에러가 나는데..mAdapter는 제대로 들어 옵니다. setAdapter 실행시 nullpointexception에러가

나는 것 같습니다. 도대체 이게 무슨일 인가요?  ㅠㅠ
