Мое приложение содержит фрагмент MyPostFragment, в который вставляются все сообщения текущего пользователя.
Я хочу:
- показать запрос, отправленный другими пользователями наэтот пост при нажатии на родительский элемент RecyclerView и добавлении его в дочерний список / дочерний RecyclerView с помощью firebase firestore.
