安卓：重置一個GridView的選擇模式爲默認

Question

與GridView相關的CAB使用下面的代碼我編程顯示：

fileDirGridView.setMultiChoiceModeListener(gridViewMultiChoiceModeListener); 
fileDirGridView.setChoiceMode(GridView.CHOICE_MODE_MULTIPLE_MODAL); 
fileDirGridView.setItemChecked(position, true); 

現在我想以解離multiChoiceModeListener和設置一切回到原來的老路它之前。要做到這一點，我使用下面的代碼總是會導致StackOverFull錯誤。

 @Override 
     public void onDestroyActionMode(ActionMode arg0) { 
      // TODO Auto-generated method stub 
      fileDirGridView.setChoiceMode(GridView.CHOICE_MODE_NONE); 

     }

我設置了choiceMode這就造成stackoverflow錯誤onDestroyActionMode()內。所以我剛剛在同一個方法中啓動了一個新線程，並在創建的線程中重置了choiceMode。

@Override 
     public void onDestroyActionMode(ActionMode mode) { 
      // TODO Auto-generated method stub 
      Thread thread = new Thread() 
      { 
       @Override 
       public void run() { 
        fileDirGridView.clearChoices(); 
        fileDirGridView.setChoiceMode(GridView.CHOICE_MODE_NONE);  
       } 
      }; 

      thread.start(); 
     }
