Question

我在通知栏上发送了一些通知，我希望在点击其中一个通知时清除所有通知。现在我通过使用Flag逐个清除。我知道notificationManager.cancelAll()可以清除所有通知，但我应该放在哪里，以便在点击通知之后我可以触发。

 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?
}

我的解决方案是在onResume()调用它。

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

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

您应该使用发送广播的待处理意图，然后放置一个取消所有通知的广播接收器。最好记住所有通知ID并逐个删除它们。

如何在点击后正确清除所有通知？
