Finishactivity不完成活動？

Question

我想讓我的活動關閉並返回結果，我在我的父活動中有onActivityResult，並且我在其他地方使用了接近下面的相同方法。

public void deleteFile(){ 
     boolean deleted=FileManager.getInstance().deleteMeasurementData(this.getIntent().getData(), this); 
     if(deleted){ 
      Toast.makeText(this, originalData.getName() +".mmd Has been deleted", Toast.LENGTH_SHORT); 
      setResult(EditMeasurement.RESULT_YES_DELETED); 
      finishActivity(EditMeasurement.RESULT_YES_DELETED); 
     }else { 
      Toast.makeText(this, originalData.getName() +".mmd did NOT delete", Toast.LENGTH_SHORT); 
      Log.e(TAG, "File did NOT delete error"); 
     } 

    } 

這種方法是從這個菜單中調用：

public boolean onOptionsItemSelected(MenuItem item) { 
     // Handle item selection 
     Log.i(TAG, "something choosen "+item.getItemId()+" it should have been: "+R.id.om_measurement_menu_delete); 

     switch (item.getItemId()) { 
     case R.id.om_measurement_menu_edit: 
      editFile(); 
      return true; 
     case R.id.om_measurement_menu_delete: 
      deleteFile(); 
      return true; 
     case R.id.om_measurement_menu_cancel: 
      endActivity(); 
      return true; 
     default: 
      return super.onOptionsItemSelected(item); 
     } 
    } 

任何有什麼好主意，爲什麼它不收？

Answer 1

finishActivity用於關閉與當前的另一項活動 - http://developer.android.com/reference/android/app/Activity.html#finishActivity(int)，所以只是將其更改爲finish();

Answer 2

我有它的光潔度（）即使有回報，但它不會關閉，後來我意識到，那個特定活動所需的android:launchMode="singleTask"在清單
