如何单击从Firebase云消息接收的推送通知来打开特定活动。我已设置为使用onMessageReceived方法下的新Intent打开所需的活动。当应用程序处于前台状态时，它可以正常工作。但是，当应用程序处于后台状态时，它则无法工作。

在使用Firebase FCM控制台时，我们不能在单击推送通知时打开活动吗？

public class MyFireBaseMessagingService extends FirebaseMessagingService {

    private static final String TAG = "FCM Service";
    private static int count = 0;

    @Override
    public void onNewToken(@NonNull String s) {
        super.onNewToken(s);
        Log.e(TAG, "onNewToken: " + s);

    }

    @Override
    public void onMessageReceived(@NonNull RemoteMessage remoteMessage) {

        Map<String,String> opendata = remoteMessage.getData();
        String actionValue = opendata.get("openactivity");

        Intent intent=new Intent();

        assert actionValue != null;
        switch (actionValue){

                case "Activity1":
                    intent=new Intent(this, Activity1.class);
                    break;
                case "Activity2":
                    intent=new Intent(this, Activity2.class);
                    break;
                
               


        }

        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        intent.putExtra("pushnotification","True");
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
        Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationManager mNotifyManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
            int importance = NotificationManager.IMPORTANCE_LOW;
            NotificationChannel mChannel = new NotificationChannel("MyID", "Myapp", importance);
            mChannel.setDescription(remoteMessage.getData().get("message"));
            mChannel.enableLights(true);
            mChannel.setLightColor(Color.RED);
            mChannel.enableVibration(true);
            mNotifyManager.createNotificationChannel(mChannel);
        }
        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, "MyID");
        mBuilder.setContentTitle(remoteMessage.getData().get("title"))
                .setContentText(remoteMessage.getData().get("message"))
                .setSmallIcon(R.mipmap.ic_launcher)
                .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.maft_logo))
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setColor(Color.parseColor("#FFD600"))
                .setContentIntent(pendingIntent)
                .setChannelId("Myid")
                .setPriority(NotificationCompat.PRIORITY_LOW);

        mNotifyManager.notify(count, mBuilder.build());
        count++;
}

}

对于其他活动的重定向，您需要一个额外的一个或多个参数来定义何时重定向。因此，使用远程消息作为附加参数，您可以使用操作键进行发送。操作键值，例如BROWSER_ACTION，PAYMENT_ACTION，UPGRADE_APP等，您必须在应用程序中定义。

Additional Fields in the cloud Message

基于此，您可以调用特定的活动。

@Override
public void onMessageReceived(@NonNull RemoteMessage remoteMessage) {
     HashMap<String,String> additionalFields = remoteMessage.getData();
     String actionValue = additionalValues.get("actionKey")
     
     switch(actionValue){
         case "BROWSER":
            //redirect to one activity
            break;
         case "HOME":
            //redirect to another activity
            break;
         case "PAYMENT":
            break;
      }
}

根据操作值，您必须定义待重定向的意图。
