情況是這樣的，使用NotificationManager觸發多個Notification:
Java代碼 ?
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));?? 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，生成的PendingIntent分別對應著不同的Intent。但是，你會發覺無論點哪個Notification，傳遞回來的都是最后被notify的Intent。這里即intent_3。
?
找了很久，試了改變PendingIntent的flag也無果，最后還是在這帖子里找到答案(CSDN帖子 )，我來總結下：
問題主要出在PendingIntent.getActivity();的第二個參數，API文檔里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。所以總是獲取到最后一個Intent。
?
只要每個不同的Intent對應傳遞一個獨立的ID就可以了，以上函數修改如下（增加ID參數）：
Java代碼 ?
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()); ??????????????????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));??
