display notification Firebase in text view

Question

I have implemented firebase cloud messaging in my app. I have been receiving messages I want to display that message in the textview of the app.

Here is the code to handle onMessageReceived..

public class FcmMessagingService extends FirebaseMessagingService {
    private Map<String, String> data;
    private static final String TAG="MyFirebaseMsgService";
    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        super.onMessageReceived(remoteMessage);
        data=remoteMessage.getData();
        String message=data.get("message");
        String titledata=data.get("title");
        ManualNotification(titledata , message);
    }
private void ManualNotification(String title , String messageBody){
        Intent intent = new Intent(this, MainActivity.class);
        Bundle bundle = new Bundle();
        bundle.putString("message", messageBody);
        intent.putExtras(bundle);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
        Bitmap bmp = BitmapFactory.decodeResource(this.getResources(),R.drawable.splash_img);
        Notification.BigPictureStyle bigpicture = new Notification.BigPictureStyle();
        bigpicture.bigPicture(bmp);
        NotificationCompat.Builder notificationBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.notifaction)
                .setContentTitle(title)
                //.setContentText(messageBody)
                .setLargeIcon(bmp)
                .setContentIntent(pendingIntent)
                .setStyle(new NotificationCompat.BigTextStyle().bigText(messageBody))
                .setContentText(messageBody).setLights(Color.YELLOW, 300, 300)
                .setVibrate(new long[] { 100, 250 })
                .setDefaults(Notification.DEFAULT_SOUND)
                .setAutoCancel(true);
        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(0, notificationBuilder.build());
    }
}

Use `BroadcastReceiver` and receive it in Activity and show on text view . If thats what you want . — ADM, Mar 24 '18 at 14:07

Send a broadcast from FcmMessagingService whenever you need to notify the Activity about it .

Intent intent = new Intent("com.push.message.received");
intent.putExtra("message", messageBody);// Add more data as per need
sendBroadcast(intent);

In Activity register a BroadcastReceiver to receive the event .

 BroadcastReceiver receiver=new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            // intent will holding data show the data here 
         String message=intent.getStringExtra("message");
          tvNotificationDetails.settext(message);
        }
    };

@Override
protected void onCreate(Bundle savedInstanceState) {
registerReceiver(receiver,new IntentFilter("com.push.message.received"));
}
@Override
protected void onDestroy() {
    unregisterReceiver(receiver);
    super.onDestroy();
}

onDestroy() is not meant to call each time So you probably unregisterReceiver in onStop() and register it in onStart().

I think there 's something wrong with my FcmMessagingService — Asmaa Mohamed, Mar 24 '18 at 20:05
