RecyclerView Item to Load Another RecyclerView with Nested JSON

Answer 1

You have to options here:

1. The two recycler views are displayed on the screen at the same time.

This will imply the data in the 2nd recylcler view need the ability to change multiple times.

Add this code in your onItemSelectListener from your cinemaRecyclerView

Cinema selectedCinema = cinemas.get(selectedPosition); // This is the selected cinema from the CinemaRecyclerView;
moviesAdapter.updateMovies(selectedCinema.getMovies);

In your MovieAdapter class add the following method.

public void updateMovies(List<Movie> movies){
    this.movies.clear();
    this.movies.addAll(movies);
    notifyDataSetChanged();
}

2. The cinema recycler view is on one screen and the movies list is on the next screen.

Here you will need to pass the selected Cinema object to the next Activity/Fragment. Based on this selection you can directly instantiate your MoviesAdapter with the correct movies list.
