Display FCM notification message in Listview onClicking Notification

I have successfully sent Firebase notifications using my own server to Android app and I want to listing the messages in a ListView in a new activity by clicking the notification. what i shoud do to notification messages are getting displayed in ListView , I want to help complete this work.

FirebaseMessageservice.java:

    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);

        Set<String> noti_set = PreferenceManager.getDefaultSharedPreferences(context).getStringSet("noti_set", new HashSet<String>());
        Set<String> set = new HashSet<String>();
        set.add(titledata+"---"+message);
        set.addAll(noti_set);
        PreferenceManager.getDefaultSharedPreferences(context).edit().putStringSet("noti_set", set).apply();

    }
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);
        Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        long[] vv = {500,1000};
        Bitmap bmp = BitmapFactory.decodeResource(this.getResources(),R.mipmap.ic_launcher);
        Notification.BigPictureStyle bigpicture = new Notification.BigPictureStyle();
        bigpicture.bigPicture(bmp);
        NotificationCompat.Builder notificationBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentTitle(title)
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setLargeIcon(bmp)
                .setSound(defaultSoundUri)
                .setVibrate(vv)
                .setContentIntent(pendingIntent);
        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(0, notificationBuilder.build());
    }
}

FcmInstanceIdService.java:

  public class FcmInstanceIdService extends FirebaseInstanceIdService {
private static final String REG_TOKEN = "REG_TOKEN";
@Override
public void onTokenRefresh() {
    String recent_token= FirebaseInstanceId.getInstance().getToken();
    SharedPreferences sharedPreferences = getApplicationContext().getSharedPreferences("FCM_TOKEN", Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = sharedPreferences.edit();
    editor.putString("FCM_TOKEN",recent_token);
    editor.apply();
    Log.d(REG_TOKEN,recent_token);
}

lst.java:

   public class lst {
private String title;
private String message;

public lst() {
}

public lst(String title, String message) {
    this.title = title;
    this.message = message;
}

public String getTitle() {
    return title;
}

public void setTitle(String title) {
    this.title = title;
}

public String getmessage() {
    return message;
}

public void setMessage(String message) {
    this.message = message;
}

} Messages.java:

  public class Messages extends AppCompatActivity {


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_list);

    Set<String> noti_set = PreferenceManager.getDefaultSharedPreferences(context).getStringSet("noti_set", new HashSet<String>());
    for (String noti : noti_set){
            String title = noti.splite("---")[0];
            String message = noti.splite("---")[1];
            list.add(new lst(title,message));
            adapter.notifyDataSetChanged();
    }

}

}

Firstly,

I will recommend you to use RecyclerView instead of ListView to show the list of Notifications. More info on how to get started here

Secondly,

onMessageRecieved(...) is only triggered/fired when your app is in Foreground so if your app is in background the notification will be received but it won't get appended to the shared preferences.

Lastly

Instead on listing/storing the notification on client side, do it in server side. If you are using Firebase I recommend you to put all the notification in a Real time database and retrieve it from there when you want it.
