Как отобразить правильный элемент из нового элемента RecyclerView в Android Studio?

Question

У меня возникла проблема с отображением нового элемента из node JS, проблема в том, что предыдущий элемент заменил новый элемент, Мой Android код

private void getDiskusiChat(String tabelchat) {
    socket.on(tabelchat, new Emitter.Listener() {
            @Override
            public void call(final Object... args) {
                if(getActivity() == null)
                    return;
                getActivity().runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        JSONObject data = (JSONObject) args[0];


                        try {
                            //extract data from fired event

                            String namaget = String.valueOf(data.getString("nama"));
                            String pesanget = String.valueOf(data.getString("pesan"));
                            String iduserget = String.valueOf(data.getString("idleveluser"));
                            String leveluserget = String.valueOf(data.getString("level"));
                            String leveluserget2 = String.valueOf(Html.fromHtml(leveluserget));
                            String replyget = String.valueOf(data.getString("reply"));
                            String createdget = String.valueOf(data.getString("created_at"));
                            Log.i("cek", "cek socket.on : " + namaget+":"+pesanget+":"
                                    +iduserget+":"+leveluserget+":"+replyget+":"+createdget);
                            String leveluserget4 = "";
                            if (leveluserget2.equals("Teacher")){
                                leveluserget4 = "teacher";
                            }else if (leveluserget2.equals("Administrator")){
                                leveluserget4 = "administrator";
                            }else if (leveluserget2.isEmpty()){
                                leveluserget4 = "member";
                            }
                            String[]pisahid = iduserget.split("-");
                            String leveluserget3 = pisahid[0];
                            SemuaChat semuaChat = new SemuaChat(leveluserget4, pesanget, replyget, createdget, namaget);

                            kelasget.add(semuaChat);
                            mAdapter = new AdapterDiskusi(mContext, kelasget);
                            mRecyclerView.getLayoutManager().onRestoreInstanceState(recyclerViewState);

                            mRecyclerView.getLayoutManager().smoothScrollToPosition(mRecyclerView,new RecyclerView.State(), kelasget.size());

                            NotificationManager notif=(NotificationManager)getActivity().getSystemService(Context.NOTIFICATION_SERVICE);
                            Notification notify= null;
                            notify = new Notification.Builder
                                    (getActivity())
                                    .setContentTitle("Pesan Baru")
                                    .setContentText(pesanget)
                                    .setContentTitle(namaget)
                                    .setSmallIcon(R.drawable.pesanmasuk)
                                    .setSound(Settings.System.DEFAULT_NOTIFICATION_URI)
                                    .build();


                            notify.flags |= Notification.FLAG_AUTO_CANCEL;
                            notif.notify(0, notify);

                        } catch (JSONException e) {
                            e.printStackTrace();
                        }
                    }
                });

            }
        });
}

Мой адаптер включен

@Override

    final SemuaChat listartikel = ChatList.get(position);

    ApiConfig apiConfig = new ApiConfig();
    holder.tgl.setText( listartikel.getCreated());
    if (ChatList.get(position).getLeveluser().equals("admin")){

Мой Node JS

io.on('connection', function (socket) {

console.log( "New client connected !" );
//console.log(socket.handshake.headers.host);

socket.on( 'new_chat_kelas', function( data ) {
    io.sockets.emit( data.tabelchat, {
        idleveluser: data.idleveluser,
        nama: data.nama,
        level: data.level,
        idchat: data.idchat,
        pesan: data.pesan,
        file: data.file,
        reply: data.reply,
        created_at: data.created_at
    });
});

это мой ScreenShoot, я могу получить данные с узла, но не могу установить c значение для имени в новом элементе

если я перефразирую sh, все возвращается в нормальное состояние, как это

Может ли кто-нибудь мне помочь? Я благодарен, если кто-то может решить мою проблему
