如何正確清除一次點擊的所有通知？

Question

我在通知欄上發送了一些通知，我想在單擊其中一個通知時清除所有通知。現在我使用標記逐一清除。我知道notificationManager.cancelAll()可以清除所有的通知，但我應該放哪裏，這樣一旦有一個通知被點擊，我就可以觸發。

private static void generateNotification(Context context, String message) { 
    int icon = R.drawable.ic_launcher; 
    long when = System.currentTimeMillis(); 
    NotificationManager notificationManager = (NotificationManager) 
      context.getSystemService(Context.NOTIFICATION_SERVICE); 
    Notification notification = new Notification(icon, message, when); 
    String title = context.getString(R.string.app_name); 
    Intent notificationIntent = new Intent(context, MainActivity.class); 

    // set intent so it does not start a new activity 
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | 
      Intent.FLAG_ACTIVITY_SINGLE_TOP); 
    PendingIntent intent = 
      PendingIntent.getActivity(context, 0, notificationIntent, 0); 
    notification.setLatestEventInfo(context, title, message, intent); 
    notification.flags |= Notification.FLAG_AUTO_CANCEL; 

    notificationManager.notify(msgid, notification); 
    //notificationManager.cancelAll(); //i wan to clear all when the notification is clicked, where should i put this line? 
}

我的解決方法是在onResume()處調用它。

@Override 
protected void onResume() { 
super.onResume(); 

// Clear all notification 
NotificationManager nMgr = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 
nMgr.cancelAll(); 
}

您應該使用待發送的廣播的意圖，然後放置廣播接收器來取消所有的通知。最好記住所有通知ID並逐一刪除它們。
