Item RecyclerView para carregar outro RecyclerView com JSON aninhado
Estou desenvolvendo um aplicativo mostrando oLista de Cinemas e também oLista de exibição de filmes em cada cinema. Quero usar 2 RecyclerViews,1 primeiro Lista os nomes dos cinemas eSegundo Um vem depois de clicar noFilmes item Do primeiro RecyclerView.
Eu uso umJSON aninhado para recuperar as informações e recuperei a lista de cinemas com êxito, mas não recebo filmes correspondentes no Second RecyclerView.
AulasCinema eCinemaAdapter são responsáveis pela recuperação de CinemaNames e Filmes usando oJSONArray, mas quero que os filmes sejam exibidos no Second RecyclerView (LoadingMovies.java classe eLoadingMoviesAdapter.java são responsáveis pelo segundo RecyclerView). AulasLoadingMovies.java eLoadingMovies.java são responsáveis por obter dados do CinemaAdapter após um clique paraMostrar a lista de filmes. (Geralmente, quero que cada cinema recarregue seus filmes de acordo com o JSON) Atualmente, recebo os dois filmes em todos os cinemas, deixando o resto não exibido.
Abaixo está o meu JSON aninhado:

Eu acho que tenho que ajustar oLoadingMovies classe, especialmente noparseResult () Método. Alguma sugestão?
