Как поместить заголовок раздела в RecyclerView?

/ 31 августа 2018

У меня уже есть список переработчиков, но затем я хочу поставить ярлык для каждого типа списка продуктов.

Я хочу достичь вот так

я не знаю, как я знаю, как составить список вот так

В каждой вкладке есть две вкладки (История платежей и Ожидающий платеж). Я уже закончил со списком, но там нет заголовка, как на картинке

Итак, я хотел спросить, как мне добавить заголовок в мой список RecyclerView для каждого типа продукта ??

Вот мой код:

item_transaction.xml
