title: 2 retrofit calls 1 adapter
body: <p>I call API for popular Movies (I need poster and title) and popular TV Shows (poster and title). I need to do it with 2 different asynchronous calls, put data into <code>List&lt;PopularMovieAdapterObject&gt; podaci</code> and <code>setAdapter</code>. Adapter is for <code>GridView</code>, so basically I need a mix of popular movies and popular tv shows in one gridview. This is my code:</p>
  
  <pre><code>       PopularMoviesFromAPI popularMoviesFromAPI = new PopularMoviesFromAPI();
  
     popularMoviesFromAPI.getPopularMoviesInfo(new PopularMoviesFromAPI.GenericCallback() {
         @Override
         public void success(@NonNull List&lt;String&gt; posterURL, List&lt;String&gt; movieTVName) {
             List&lt;PopularMovieAdapterObject&gt; podaci = new ArrayList&lt;&gt;();
             for(int i=0; i&lt;(posterURL.size()/2); i++){
                 podaci.add(new PopularMovieAdapterObject("https://image.tmdb.org/t/p/w500" + posterURL.get(i), movieTVName.get(i)));
             }
  
             PopularMoviesAdapter popularMoviesAdapter = new PopularMoviesAdapter(getContext(), R.layout.popular_movies_item, podaci);
  
             popularMoviesGridView.setAdapter(popularMoviesAdapter);
         }
  
         @Override
         public void failure(@NonNull Throwable throwable) {
  
         }
     });
  
     popularMoviesFromAPI.getPopularTVShowsInfo(new PopularMoviesFromAPI.GenericCallback() {
         @Override
         public void success(@NonNull List&lt;String&gt; posterURL, List&lt;String&gt; movieTVName) {
             List&lt;PopularMovieAdapterObject&gt; podaci = new ArrayList&lt;&gt;();
             for(int i=0; i&lt;(posterURL.size()/2); i++){
                 podaci.add(new PopularMovieAdapterObject("https://image.tmdb.org/t/p/w500" + posterURL.get(i), movieTVName.get(i)));
             }
  
             PopularMoviesAdapter popularMoviesAdapter = new PopularMoviesAdapter(getContext(), R.layout.popular_movies_item, podaci);
  
             popularMoviesGridView.setAdapter(popularMoviesAdapter);
         }
  
         @Override
         public void failure(@NonNull Throwable throwable) {
  
         }
     });
  </code></pre>
  
  <p>Right now I can either put movies OR tv shows in <code>GridView</code>.</p>
