情況是這樣的，使用NotificationManager觸發多個Notification:

private Notification genreNotification(Context context, int icon, String tickerText, String title, String content, Intent intent){          Notification notification = new Notification(icon, tickerText, System.currentTimeMillis());          PendingIntent pendIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);          notification.setLatestEventInfo(context, title, content, pendIntent);          notification.flags |= Notification.FLAG_AUTO_CANCEL;          return notification;      }    ...  mNotificationManager.notify(ID_1,                       genreNotification(mContext, ICON_RES,                               notifyText1, notifyTitle1, notifyText1, intent_1));  ...  mNotificationManager.notify(ID_2,                       genreNotification(mContext, ICON_RES,                               notifyText2, notifyTitle2, notifyText2, intent_2));    ...  mNotificationManager.notify(ID_3,                       genreNotification(mContext, ICON_RES,                               notifyText3, notifyTitle3, notifyText3, intent_3));  

可見ID和Intent都是不同的，產生的PendingIntent分別對應著不同的Intent。但是，你會發覺無論點哪個Notification，傳遞迴來的都是最後被notify的Intent。這裡即intent_3。

 

找了很久，試了改變PendingIntent的flag也無果，最後還是在這文章裡找到答案(CSDN文章 )，我來總結下：

問題主要出在PendingIntent.getActivity();的第二個參數，API文檔裡雖然說是未被使用的參數(給出的例子也直接寫0的)，實際上是通過該參數來區別不同的Intent的，如果id相同，就會覆蓋掉之前的Intent了。所以總是擷取到最後一個Intent。

private Notification genreNotification(Context context, int icon, String tickerText, String title, String content, Intent intent, int id){          Notification notification = new Notification(icon, tickerText, System.currentTimeMillis());          // 問題就在這裡的id了          PendingIntent pendIntent = PendingIntent.getActivity(context, id, intent, PendingIntent.FLAG_UPDATE_CURRENT);          notification.setLatestEventInfo(context, title, content, pendIntent);          notification.flags |= Notification.FLAG_AUTO_CANCEL;          return notification;      }    ...  mNotificationManager.notify(ID_1,                       genreNotification(mContext, ICON_RES,                               notifyText1, notifyTitle1, notifyText1, intent_1, ID_1));  ...  mNotificationManager.notify(ID_2,                       genreNotification(mContext, ICON_RES,                               notifyText2, notifyTitle2, notifyText2, intent_2, ID_2));    ...  mNotificationManager.notify(ID_3,                       genreNotification(mContext, ICON_RES,                               notifyText3, notifyTitle3, notifyText3, intent_3, ID_3));
