Android:在状态栏中管理多个通知

private void updateNotification(int notificationId, int clockStatusID, CharSequence text) {
   // notificationManager.cancel(notificationId);
    // throws up an ongoing notification that the timer is running
    Log.i("TIMERCOUNT", "Notification id: " + notificationId);
    Notification not = new Notification(clockStatusID, // the
        // icon
        // for
        // the
        // status
        // bar
        text, // the text to display in the ticker
        System.currentTimeMillis() // the timestamp for the
        // notification to appear
    );
    Intent intent = new Intent();
    intent.setClassName("com.intuit.time_catcher.android.activities",
    "com.intuit.time_catcher.android.activities.Tabs");
    not.setLatestEventInfo(self,
        getText(R.string.timer_notification_title),
        getText(R.string.timer_on_notification_text), PendingIntent
        .getActivity(this, 0, intent,
            PendingIntent.FLAG_UPDATE_CURRENT));
    not.flags += Notification.FLAG_ONGOING_EVENT;
    not.flags += Notification.FLAG_NO_CLEAR;
    notificationManager.notify(notificationId, not);

}

下面是我面临的问题。 假设状态栏中有3个正在运行的计时器和3个通知。当我更新定时器2时,通知3(在最右边)会被更新,但我真正想做的是更新第二个通知(中间的一个)。 当我打印通知id时,我看到了正确的值。
