如何在Android上从retrofit response中获取嵌套的JSON对象和数组？

public interface ApiService {
    @GET("your_api_endpoint")
    Call<YourResponseModel> getResponse();
}

public class YourResponseModel {
    private String field1;
    private int field2;
    private NestedObject nestedObject;
    private List<NestedArrayItem> nestedArray;

    // Getters and setters
}

public class NestedObject {
    private String nestedField;

    // Getters and setters
}

public class NestedArrayItem {
    private String arrayField;

    // Getters and setters
}

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("your_base_url")
        .addConverterFactory(GsonConverterFactory.create())
        .build();

ApiService apiService = retrofit.create(ApiService.class);

apiService.getResponse().enqueue(new Callback<YourResponseModel>() {
    @Override
    public void onResponse(Call<YourResponseModel> call, Response<YourResponseModel> response) {
        if (response.isSuccessful()) {
            YourResponseModel yourResponse = response.body();
            // 获取嵌套的JSON对象和数组
            NestedObject nestedObject = yourResponse.getNestedObject();
            List<NestedArrayItem> nestedArray = yourResponse.getNestedArray();
            // 处理获取到的数据
        } else {
            // 处理请求失败的情况
        }
    }

    @Override
    public void onFailure(Call<YourResponseModel> call, Throwable t) {
        // 处理请求失败的情况
    }
});
