мне нужна помощь с NestedRecyclerView, я следую за этим web для вложенного просмотра переработчика, я создаю форму с NestedRecyclerView, когда нажимаю кнопку отправки, я получу все значения из NestedRecyclerView
я использую этот код для recyclerView child внутри родительского recyclerview.

код работает только с одним recyclerView, но во вложенном recyclerView показывать только последний элемент строки, мне нужен совет для этой проблемы.
