在 android studio 单击推送通知后重定向到特定 activity

Question

我正在努力开发一个 Android 应用程序，以便在单击所有传入推送通知时将应用程序重定向到特定的 activity 页面。我是 android 开发的新手，对我的编程感到抱歉。

下面是androidmanifest.xml的推送通知部分。如果对此主题有任何评论，我们将不胜感激：-

    <!-- Push Notifications Service -->

    <!-- /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);
