无法从Retrofit 2获得响应

Question

使用翻新无法理解错误所在。 只要从入队什么都不返回。 即我的结果和列表为0； 给出了Json响应

Retrofit.Builder builder = new Retrofit.Builder()
    .baseUrl("https://api.themoviedb.org/3/")
    .addConverterFactory(GsonConverterFactory.create());

Retrofit retrofit = builder.build();
MovieClient client = retrofit.create(MovieClient.class);

Call<Result> resultCall = client.getMoviesList();

List<Movie> resultFromApi = new ArrayList<>();

resultCall.enqueue(new Callback<Result>() {
  @Override
  public void onResponse(Call<Result> call, Response<Result> response) {
    resultFromApi.addAll(response.body().getResults());
  }

  @Override
  public void onFailure(Call<Result> call, Throwable t) {
    //callback.onDataNotAvailable();
    Log.e(TAG, "onFailure: error");
  }
});

MovieClient.java

@GET("movie/popular?api_key=my_key")
Call<Result>getMoviesList();

Result.java

@SerializedName("results")
@Expose
private List<Movie> results;

public List<Movie> getResults() {
    if (results == null) {
        return new ArrayList<>();
    }
    return results;
}

提供了来自API的JSON响应

JSON响应：

先感谢您！

您的Movie.java类必须是这样的

public class Movie {

@SerializedName("vote_count")
@Expose
private Integer voteCount;
@SerializedName("id")
@Expose
private Integer id;
@SerializedName("video")
@Expose
private Boolean video;
@SerializedName("vote_average")
@Expose
private Double voteAverage;
@SerializedName("title")
@Expose
private String title;
@SerializedName("popularity")
@Expose
private Double popularity;
@SerializedName("poster_path")
@Expose
private String posterPath;
@SerializedName("original_language")
@Expose

public String getReleaseDate() {

}
