如何在android中使用改型和GSON从api获得完整的JSON响应

Question

   ApiInterface apiService =
                ApiClient.getClient().create(ApiInterface.class);

        Call<ProductResponse> call = apiService.getProducts();
        call.enqueue(new Callback<ProductResponse>() {
            @Override
            public void onResponse(Call<ProductResponse> call, Response<ProductResponse> response) {
                List<Category> categories = response.body().getResults();
                Log.d("cat", "Number of categories received: " + categories.size());
            }

            @Override
            public void onFailure(Call<ProductResponse> call, Throwable t) {
                // Log error here since request failed
                Log.e("cat", t.toString());
            }
        });


public interface ApiInterface {

    @GET("/json")
    Call<ProductResponse> getProducts();

}


public class ApiClient {
    public static final String BASE_URL = "https://stark-spire-93433.herokuapp.com/";
    private static Retrofit retrofit = null;


    public static Retrofit getClient() {
        if (retrofit==null) {
            retrofit = new Retrofit.Builder()
                    .baseUrl(BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();
        }
        return retrofit;
    }
}

我的JSON：

{
  "categories": [
    {
      "id": 1,
      "name": " Casuals",
      "products": [
        {
          "id": 1,
          "name": "Nike Sneakers",
          "date_added": "2016-12-09T11:16:11.000Z",
          "variants": [
            {
              "id": 1,
              "color": "Blue",
              "size": 42,
              "price": 1000
            },
            {
              "id": 2,
              "color": "Red",
              "size": 42,
              "price": 1000
            },
            {
              "id": 3,
              "color": "Blue",
              "size": 44,
              "price": 1200
            },

上面的代码是什么我有treid，所以可以任何一个请帮助我获得整个响应不仅是父类别。

我想你把所有的模型类都做得很好。然后替换

@GET("/json")
Call<ProductResponse> getProducts();

与

@GET("json")
Call<ProductResponse> getProducts();

如果它不起作用，那么就发表评论。我还将提供模型类。
