当应用程序处于后台/未运行时，不打开通知单击上的特定活动

仅当打开应用程序并执行通知单击时，通知单击才会启动指定的活动。如果应用程序处于后台/未运行并且执行了通知单击，则应用程序的 MainActivity 将打开。简而言之，就像应用程序按照 Activity 堆栈正常打开一样，而不是打开 PendingIntent 中指定的 Activity。

我想根据其类型将通知点击重定向到两个不同的活动（ApprovalDetailActivity 和 ConversationDetailActivity）。

我正在使用 FCM 进行推送通知。我将清单文件和 FCMListener 文件粘贴到此处。请帮帮我。

发送通知()MyFirebaseMessagingService.java 中的函数

private void sendNotification(String messageBody)
    {
        Intent intent;
        System.out.println("----message body: " + messageBody);
        if(notificationBundle.getCategory().equalsIgnoreCase(Master.KEY_PUSH_NOTIFICATION_CONVERSATION))
        {
            intent = new Intent(this, ConversationDetailActivity.class);
            /*Conversation conversation = Master.notificationBundle.getConversation();
            Master.conversationsList = new ArrayList<>();
            Master.conversationsList.add(conversation);*/
        }
        else
        {
            intent = new Intent(this, ApprovalDetailActivity.class);
            if(notificationBundle.getApprovalType().equals("I"))
                intent.putExtra(Master.KEY_WHICH_APPROVAL, Master.KEY_VERIFICATIONS);
            else if(notificationBundle.getApprovalType().equals("A"))
                intent.putExtra(Master.KEY_WHICH_APPROVAL, Master.KEY_APPROVALS);
            else
                intent.putExtra(Master.KEY_WHICH_APPROVAL, Master.KEY_COMPLETED);

            intent.putExtra(Master.KEY_IS_FROM_CONVERSATION, false);
        }

        intent.putExtra(Master.KEY_PUSH_NOTIFICATION_POST_ID , notificationBundle.getPostID());
        intent.putExtra(Master.KEY_IS_FROM_PUSH_NOTIFICATION, true);
        intent.putExtra(Master.KEY_POSITION, 0);

        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
                PendingIntent.FLAG_ONE_SHOT);

        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.mnet_icon)
                .setContentTitle(getString(R.string.app_name))
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

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

        int random = (int) ((new Date().getTime() / 1000L) % Integer.MAX_VALUE);
        notificationManager.notify(random, notificationBuilder.build());
    }

根据 Firebase Cloud Messaging 文档 - 如果 Activity 位于前台，则将调用 onMessageReceived。如果活动在后台或关闭，则通知消息将显示在应用程序启动器活动的通知中心。欲了解更多信息，请查看此链接 https://firebase.google.com/docs/cloud-messaging/android/receive
