当我的应用在前台时，如何删除通知图标

Question

我面临一些问题需要您的帮助，我将我的应用程序放在前景，当我从服务器发送通知时，通知随附通知图标。

但是我需要的是，当我的应用在前景用户看到通知时，不应向用户显示通知图标。

当我的应用在后台/或未启动应用程序时，请使用通知图标的通知来临，然后用户按Notification Icon，然后通知图标被视为完美工作。

我尝试过：

if(getIntent()!=null ){
        Log.e("getIntent","getIntent");
        broadcastReciver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                if (intent.getAction().equals(NOTIFY_ACTIVITY_ACTION ))
                {
                    if(intent.getExtras().getBoolean("reload")){
                        int notificationId = intent.getIntExtra("notificationId", 0); 
                        Log.e("notificationId","notificationId---"+notificationId);
                        NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
                        manager.cancel(notificationId);
                        setFragmentView(0);
                        //finish();
                    }
                }
            }
        };
    }

在OnMessagereceived中：

Intent intent = new Intent(this, MainActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        intent.putExtra("notificationId",NOTIFICATION_ID);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
                PendingIntent.FLAG_ONE_SHOT);
        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.splash_logo)
                .setContentTitle("Logizo")
                .setContentText("New Order Arrived")
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);
        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        notificationBuilder.getNotification().flags |= Notification.FLAG_AUTO_CANCEL;
        notificationManager.notify(NOTIFICATION_ID/* ID of notification */, notificationBuilder.build());

i通过使用以下代码删除通知图标。

 private void removeNotificationsFromStatusBar(Context context, int notificationId) {
    try {
        NotificationManager notificationManagerNS = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManagerNS.cancel(notificationId);
    } catch (Exception e) {
        e.printStackTrace();
        Log.e(NotificationsFragment.class.getSimpleName(), "Unable to remove notification from status bar");
    }
}
