在 android studio 上单击推送通知后重定向到特定活动

Question

每当单击所有传入的推送通知时，我都在努力开发 Android 应用程序以将应用程序重定向到特定的活动页面。我是 android 开发新手，对我的编程感到抱歉。

以下是推送通知部分的 android manifest.xml。如果对此主题有任何评论，我们将不胜感激：-

    <!-- /Push Notifications Receiver -->


    <!-- Push Notifications Service -->
    <service android:name=".backgroundservices.PushnotificationService" />
    <!-- /Push Notifications Service -->

你可以试试这样的

NotificationManager notificationManager = (NotificationManager) context
        .getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, message, when);

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);
