我正在尝试使用Retrofit获取响应并在json响应中显示来自url的图像。我不知道如何调试Retrofit。我进入“失败”区块并看到我的“失败”吐司。这是一些代码：
主要活动：
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();
}
});
}
}
我的适配器：
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;
}
}
我的界面：
public interface apiLocation {
@GET("/3/movie/popular?my api key")
void getData(Callback<List<MovieModel>> response);
}

答案 0 :(得分：0)
您正在获取一个对象，但期待一个数组。您需要一个POJO模型来响应popular端点的响应。根据文档，它看起来像这样 -
class MovieDBResponse {
int page;
List<MovieModel> results;
int total_pages;
int total_results;
}
然后将您的界面更改为 -
public interface apiLocation {
@GET("/3/movie/popular?my api key")
void getData(Callback<List<MovieDBResponse>> response);
}
更新适配器以解压缩results以用作MovieModel s
