我在列表視圖的setOnItemClickListener上遇到錯誤

我試圖通過一個意圖傳遞數據，但它拋出一個錯誤，我不明白。我在列表視圖的setOnItemClickListener上遇到錯誤

活動：

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_editor); 
    conn = new ConnectionDetector(this); 
    mEditorAdapater = new EditorAdapter(this, new ArrayList<ParseObject>()); 
    mListView = (ListView) findViewById(R.id.listEditor); 
    mListView.setAdapter(mEditorAdapater); 
    swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipe_refresh_layout_edit); 
    swipeRefreshLayout.setOnRefreshListener(this); 
    swipeRefreshLayout.post(new Runnable() { 
     @Override 
     public void run() { 
      swipeRefreshLayout 
        .setRefreshing(true); 
      queryPieces(); 
     } 
    }); 

    mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 

      String title = pieces.get(position).getString("title"); 
      String status = pieces.get(position).getString("status"); 
      String story = pieces.get(position).getString("story"); 
      String category = pieces.get(position).getString("category"); 
      String location = pieces.get(position).getString("location"); 
      String journo = pieces.get(position).getString("Journo"); 
      String objectId = pieces.get(position).getObjectId(); 
      // byte[] storyClip = pieces.get(position).getBytes("storyClip"); 
      Intent in = new Intent(Editor.this, EditPieceActivity.class); 
      in.putExtra("title", title); 
      in.putExtra("status", status); 
      in.putExtra("story", story); 
      in.putExtra("category", category); 
      in.putExtra("location", location); 
      in.putExtra("id", objectId); 
      startActivity(in); 
      //in.putExtra() 
     } 
    }); 

    pieces = new ArrayList<ParseObject>(); 
}

，這是錯誤我得到Android是不是在告訴我什麼是錯的幫助。

錯誤：

你的作品arraylist是空的......它被初始化但沒有值它在...所以檢查是否您正在將數據正確添加到arraylist中 –

您正在向適配器發送空數據。看到您正在適配器中創建新對象。 mEditorAdapater = new EditorAdapter（this，** new ArrayList （）**）; 我不知道你是如何填充你的列表視圖。而logcat說你的'pieces' ArrayList也是空的。 – Kunu

這是你的「作品」數組列表中 - 它沒有任何關係開始一個新的活動，或通過一個意圖傳遞數據的問題。也許在onItemClick方法中評論一切，並把

log.v（「PIECES SIZE：」，「」+ pieces.size（））;

如果這個記錄爲0，那麼你知道你的問題在於該數組中。
