Estoy desarrollando una aplicación que muestra elLista de cines y también elLista de películas que se muestran en cada cine. Quiero usar 2 RecyclerViews,Uno primero enumera los nombres de cine, y elSegundo Uno viene después de hacer clic en elPelículas elemento del primer RecyclerView.

Uso unJSON anidado para recuperar la información, y he recuperado con éxito la lista de cines, pero no recibo películas coincidentes en el Second RecyclerView.

ClasesCinema yCinemaAdapter son responsables de recuperar CinemaNames y Películas mediante el uso deJSONArray, pero quiero que las películas se muestren en Second RecyclerView (LoadingMovies.java clase yLoadingMoviesAdapter.java La clase es responsable del segundo RecyclerView). ClasesLoadingMovies.java yLoadingMovies.java son responsables de obtener datos de CinemaAdapter después de hacer clic paraMostrar la lista de películas. (En general, quiero que cada cine vuelva a cargar sus películas de acuerdo con el JSON) Actualmente obtengo las dos películas aame en todos los cines, dejando el resto sin mostrar.

A continuación se muestra mi JSON anidado:
