Как отлаживать Почему нет ответа с помощью дооснащения

Question

Я пытаюсь получить ответ с помощью «Дооснащения» и отображения изображений с URL-адреса в ответном сообщении json. Я не знаю, как отлаживать для Retrofit. Я попадаю в блок «Сбой» и вижу тосты «Fail». Вот код:

Основная деятельность:

public class TheMovieDbActivity extends Activity { 

    private GridView gridView; 
    private List<MovieModel> movieModelsList; 
    private String ENDPOINT_URL = "https://api.themoviedb.org"; 


    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.movie_db_activity); 

     gridView = (GridView) findViewById(R.id.gridView); 

     final RestAdapter restadapter = new RestAdapter.Builder().setEndpoint(ENDPOINT_URL).build(); 

     apiLocation apiLocation = restadapter.create(apiLocation.class); 

     apiLocation.getData(new Callback<List<MovieModel>>() { 
      @Override 
      public void success(List<MovieModel> movieModels, Response response) { 
       movieModelsList = movieModels; 
       MoviesGridViewAdapter adapter = new MoviesGridViewAdapter(getApplicationContext(), R.layout.movie_gridview_item, movieModelsList); 
       gridView.setAdapter(adapter); 
      } 


      @Override 
      public void failure(RetrofitError error) { 
       Toast.makeText(getApplicationContext(), "Failed", Toast.LENGTH_SHORT).show(); 
      } 
     }); 
    } 
} 

Мой адаптер:

public class MoviesGridViewAdapter extends ArrayAdapter<MovieModel> { 

    String url="http://services.hanselandpetal.com/photos/"; 

    private Context context; 
    private List<MovieModel> movieModelList; 
    LayoutInflater inflater; 

    public MoviesGridViewAdapter(Context context, int resource, List<MovieModel> objects) { 
     super(context,resource,objects); 
     this.context = context; 
     this.movieModelList = objects; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     LayoutInflater inflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE); 
     View view = inflater.inflate(R.layout.movie_gridview_item, parent, false); 
     MovieModel movieModel = movieModelList.get(position); 
     ImageView img = (ImageView) view.findViewById(R.id.grid_item_image); 
     Picasso.with(getContext()).load(url+movieModel.getPosterPath()).resize(100, 100).into(img); 
     return view; 
    } 
} 

И мой интерфейс:

public interface apiLocation { 
    @GET("/3/movie/popular?my api key") 
    void getData(Callback<List<MovieModel>> response); 
}

Answer 1

Вы получаете объект, но ожидает массив. Вам нужна модель POJO для ответа конечной точки popular. На основании документации, это выглядит примерно так -

class MovieDBResponse { 
    int page; 
    List<MovieModel> results; 
    int total_pages; 
    int total_results; 
} 

затем изменить свой интерфейс -

public interface apiLocation { 
    @GET("/3/movie/popular?my api key") 
    void getData(Callback<List<MovieDBResponse>> response); 
} 

обновления адаптера для извлечения results для использования в качестве списка MovieModel s
