【问题描述】：

我希望我的应用程序应该给我通知，并在点击通知时打开另一个活动，例如 whatsapp 通知 这是我的代码 c 有人帮忙吗？？？

 public class MyFirebaseMessagingService extends FirebaseMessagingService 
        @Override
        public void onMessageReceived(RemoteMessage remoteMessage) 
            //    sendNotification(remoteMessage.getNotification().getBody());
            //Bundle bundle=new Bundle();
            //bundle.putString("msgBody",remoteMessage.getNotification().getBody());
            //intent use for start this activity after click on notification
            Intent intent = new Intent(getApplicationContext(),Secondactivity.class);
            String valu=remoteMessage.getNotification().getBody();
            intent.putExtra("notificationmessage",valu);
**strong text**            //here we are telling system after clicking you have to come on mainactivity
            intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            //here we are giving rights to main activity.FLAG_ONE_SHOT useful to indicate this pending intent can use only once
            PendingIntent pendingintent=PendingIntent.getActivity(this,0,intent,PendingIntent.FLAG_ONE_SHOT);
            //notificationcompat useful for creating notification layout
            NotificationCompat.Builder notificationbuilder=new  NotificationCompat.Builder(this);
            notificationbuilder.setContentText(remoteMessage.getNotification().getBody());
            notificationbuilder.setContentTitle("FCM NOTIFICATION");
            notificationbuilder.setSmallIcon(R.mipmap.ic_launcher);
            notificationbuilder.setAutoCancel(true);
            notificationbuilder.setContentIntent(pendingintent);

            NotificationManager notificationManager= (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
            notificationManager.notify(0,notificationbuilder.build());

        

【参考方案1】：

您必须在消息内容中添加一个额外的参数来识别类型。然后根据该类型值创建具有不同活动的通知管理器。

例如：

switch (type)
case 1:

 notification manager for activity A

break:

case 2:

 notification manager for activity B

break:
