Чат не отображается должным образом на экране

Question

Я создал чат-бота с помощью Dialogflow и подключил его к Android и Firebase.Теперь, когда я набираю сообщение от пользователя, правильный ответ получен от бота и сохранен в базе данных.Но я не могу передать и приветствие, и ответ на созданный мной макет.

Ниже приведен код для основного действия Chatbot.

RecyclerView chatbotMainRecyclerView;
EditText chatbotMainEditxt;
RelativeLayout chatbotMainbtnAdd;

DatabaseReference chatbotDatabaseRef;
FirebaseRecyclerAdapter<ChatMessage, ChatViewHolder> adapter;

private AIService aiService;


@Override

    super.onCreate(savedInstanceState);
