片段不能轉換爲通知android.app.activity點擊

-1

我有一個通知管理器在一個片段，它工作正常，直到你點擊它，它是假設打開Fragment_02類，無論它被點擊（是它從主屏幕，另一個片段或活動）片段不能轉換爲通知android.app.activity點擊

下面

代碼：

  private void pushNotification(int Request_ContactIntTotal) { 

      NotificationManager NM = (NotificationManager) getActivity().getSystemService(Context.NOTIFICATION_SERVICE); 

      if (Request_ContactIntTotal == 0) 
      { 
       NM.cancelAll(); 
      } 
      else 
      { 
        NotificationCompat.Builder builder = new NotificationCompat.Builder(getActivity()); 
        builder.setSmallIcon(R.drawable.ic_launcher); 
        builder.setContentTitle("Message Notification"); 
        uilder.setContentText(Request_ContactIntTotal + " unread messages"); 
        Intent intent = new Intent(getActivity(),Fragment_02.class); 
        TaskStackBuilder stackBuilder = TaskStackBuilder.create(getActivity()); 
        stackBuilder.addParentStack(Fragment_02.class); 
        stackBuilder.addNextIntent(intent); 
        PendingIntent pendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT); 
        builder.setContentIntent(pendingIntent); 
        NM.notify(0,builder.build()); 
      } 
     }

通知點擊給出錯誤：Fragment_02不能轉換到Android應用活動

[Fragment無法轉換爲android.app.activity]的可能重複（http://stackoverflow.com/questions/22705146/fragment-cannot-be-cast-to-an-android-app-activity） – Sufian

它是一個片段。所以你不能打開它，你寫

嘗試：

FragmentManager fragmentManager = getFragmentManager(); 
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction(); 
Fragment_02 fragment = new Fragment_02(); 
fragmentTransaction.add(R.id.fragment_container, fragment); 
fragmentTransaction.commit();

它會幫助你。

docs表示addParentStack可以取3個不同的參數不包含片段。我的建議是調用addParentStack，其中包含活動類和活動中的開始片段。
