Question

当应用程序正在运行时，如果我点击它就会发出通知，通知会转到那里（onMessageReceived正在运行）

但是当应用程序处于后台并且如果我点击它时通知是警报，则会再次重新加载应用程序（首先是启动画面），而不是去那里且onMessageReceived没有运行

如何解决？

PS。抱歉，我的英语不好。

Answer 1

您需要将所需的活动作为意图传递，而不是MainActivity

Answer 2

将活动名称提供给待处理的意图....

      Intent intent = new Intent(this, NotificationCheck.class);       
      intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
      PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
            PendingIntent.FLAG_ONE_SHOT);

    Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("App Name")
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setStyle(new NotificationCompat.BigTextStyle().bigText(messageBody))
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

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

    notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());

见下面的代码。我正在使用它，它正在打开我的HomeActivity。

NotificationManager notificationManager = (NotificationManager) context
        .getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, message, when);
//change HomeActivity.class which activity you want to open after clicking notification
Intent notificationIntent = new Intent(context, HomeActivity.class);

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(0, notification);

更改HomeActivity.class点击通知后要打开哪个活动..希望它能正常工作......

/**
 * Method checks if the app is in background or not
 */
public static boolean isAppIsInBackground(Context context) {
    boolean isInBackground = true;
    ActivityManager am = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
    if (Build.VERSION.SDK_INT > Build.VERSION_CODES.KITKAT_WATCH) {
        List<ActivityManager.RunningAppProcessInfo> runningProcesses = am.getRunningAppProcesses();
        for (ActivityManager.RunningAppProcessInfo processInfo : runningProcesses) {
            if (processInfo.importance == ActivityManager.RunningAppProcessInfo.IMPORTANCE_FOREGROUND) {
                for (String activeProcess : processInfo.pkgList) {
                    if (activeProcess.equals(context.getPackageName())) {
                        isInBackground = false;
                    }
                }
            }
        }
    } else {
        List<ActivityManager.RunningTaskInfo> taskInfo = am.getRunningTasks(1);
        ComponentName componentInfo = taskInfo.get(0).topActivity;
        if (componentInfo.getPackageName().equals(context.getPackageName())) {
            isInBackground = false;
        }
    }

    return isInBackground;
}

您可以检查app是否在后台，然后在MyFirebaseMessagingService类中，您可以使用此方法处理句柄消息并处理通知。

private void handleNotification(String message) {
    if (!NotificationUtils.isAppIsInBackground(getApplicationContext())) {
        // app is in foreground, broadcast the push message
        Intent pushNotification = new Intent(Config.PUSH_NOTIFICATION);
        pushNotification.putExtra("message", message);
        LocalBroadcastManager.getInstance(this).sendBroadcast(pushNotification);

        // play notification sound
        NotificationUtils notificationUtils = new NotificationUtils(getApplicationContext());
        notificationUtils.playNotificationSound();
    }else{
        // If the app is in background, firebase itself handles the notification
    }
}

我希望它可以帮到你。

应用程序重新加载如果应用程序在后台时单击firebase通知
