我正在开发一个使用 Firebase Cloud Messaging 的应用程序。但是我有一种情况，应用程序已关闭，处于终止状态，并且用户在 10 秒后未单击通知栏如何自动关闭此通知。我的问题是：当应用程序处于终止状态并且通知位于系统托盘中时，如何自动关闭此通知。

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    private static final String ChannelID = "Qwykr";
    public static final int NOTIFICATION_ID = 1041;
    NotificationManager notificationManager;
    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        String RiderLOcation = remoteMessage.getData().get("RiderLocation");
        String RiderID = remoteMessage.getData().get("RiderID");
        String Dlat = remoteMessage.getData().get("Dlat");
        String DLong = remoteMessage.getData().get("DLong");
        String Plat = remoteMessage.getData().get("Plat");
        String Plong = remoteMessage.getData().get("Plong");
        String RiderName = remoteMessage.getData().get("RiderName");
        String MainBody="RiderID:"+RiderID+";RiderName:"+RiderName+";RiderLocation:"
                +RiderLOcation+";PLat:"+Plat+";PLong:"+Plong+";DLat:"+Dlat+";DLong:"+DLong;
        System.out.println("notificationIntentIs  On Recevied"+MainBody);
        sendNotification(MainBody);
        PreferenceHandler.writeString(this, PreferenceHandler.RIDE_DETAIL,MainBody);

    }

    private void sendNotification(String messageBody) {

        Intent intent = new Intent(this, MainActivity.class);
        Bundle bundle = new Bundle();
        bundle.putString("bookingId", messageBody);
        intent.putExtras(bundle);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

        PendingIntent pendingIntent = PendingIntent.getActivity(this,
                0 /* Request code */, intent,
                PendingIntent.FLAG_ONE_SHOT);
        startActivity(intent);
        Intent YesButton = new Intent(this, MainActivity.class);
        Bundle bundle1 = new Bundle();
        bundle1.putString("bookingId", messageBody);
        YesButton.putExtras(bundle1);
        YesButton.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK|
                Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent YesPendingIntent = PendingIntent.getActivity(this, 0,
                YesButton,
                PendingIntent.FLAG_ONE_SHOT);
        String channelId = getString(R.string.default_notification_channel_id);
        Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder =
                new NotificationCompat.Builder(this, channelId)
                        .setSmallIcon(R.drawable.logo)
                        .setVibrate(new long[] { 1000, 1000, 1000, 1000, 1000 })
                        .setLights(Color.BLUE, 100, 3000)
                        .setPriority(Notification.DEFAULT_ALL)
                        .setDefaults(Notification.DEFAULT_ALL)
                        .setWhen(System.currentTimeMillis())
                        .setContentTitle(getResources().getString(R.string.app_name))
                        .setContentText(getString(R.string.notificationData))
                        .setSound(defaultSoundUri)
                        .setAutoCancel(true)
                        .setContentIntent(pendingIntent);

         notificationManager =(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);


        // Since android Oreo notification channel is needed.
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel channel = new NotificationChannel(channelId,
                    "Channel human readable title",
                    NotificationManager.IMPORTANCE_DEFAULT);
            notificationManager.createNotificationChannel(channel);
        }
        notificationManager.notify(NOTIFICATION_ID /* ID of notification */,
                notificationBuilder.build());
        clearNotification(NOTIFICATION_ID);

    }

    public  void clearNotification(int ID) {
       Handler handler=new Handler(Looper.getMainLooper()) {
            @Override
            public void handleMessage(Message message) {
            }
        };
        Runnable doDisplayError = new Runnable() {
            public void run() {
                notificationManager.cancel(ID);
            }
        };




handler.postDelayed(doDisplayError,3000);

}
}

您可以采取的解决方法来实现此功能：

根据您的要求使用Alarm Manager和设置它的时间，并附上广播接收器。当时间到达您的应用程序会收到回调[ onReceive(Context context, Intent intent)]，您可以使用通知 ID 取消通知。

使用 NotificationManager 从 NotificationId 获取通知。

对于通知 ID，您可以将其存储偏好或在 Db 中，这取决于您的要求，您有多少 id。

希望这会帮助你。
