Question

我正在使用改造/ okhttp。我通过改造搜索了一些关于处理嵌套JSON对象的问题，并得到了我的答案from here，根据结果使用了几个POJO类。

这是一种简单的方法，我可以根据我需要的元素直接解析JSON对象吗？
例如我有一个JSON结果

{
"DealsViewModel": {
"CountryDealsViewModel": {
  "CultureCountry": "string",
  "CultureLanguage": "string",
  "DealsPageInfo": [
    {
      "DisplayName": "string",
      "StartDate": "2018-05-07T06:43:31.179Z",
      "ExpiredDate": "2018-05-07T06:43:31.179Z",
      "Url": "string",
      "ImageUrl": "string",
      "ShortDescription": "string"
    }
  ],
  "CountryCode": "string",
  "CountryName": "string"
}
},
"Status": 0,
"Code": 0,
"Message": "string"
}

从结果来看，如果按照上一个答案的方法，我需要有大约4个POJO文件来处理结果，但我只需要“状态”“代码”“消息”和“ DealsPageInfo“

这是否可以让我有这样的东西？

public class ExclusiveOffersParent {
private List<ExclusiveOffers> DealsPageInfo;
private String Message;
private int Status;
private int Code;

public ExclusiveOffersParent() {
    this.DealsPageInfo = new ArrayList<>();
}

public List<ExclusiveOffers> getDeals() {
    return DealsPageInfo;
}

public void setDeals(List<ExclusiveOffers> deals) {
    DealsPageInfo = deals;
}

public String getMessage() {
    return Message;
}

public void setMessage(String message) {
    Message = message;
}

public int getStatus() {
    return Status;
}

public void setStatus(int status) {
    Status = status;
}

public int getCode() {
    return Code;
}

public void setCode(int code) {
    Code = code;
}
}

Answer 1

你必须为所有孩子制作pojo：

转到http://www.jsonschema2pojo.org/
将json粘贴到方框
插入包名和类名
从源类型中选择JSON
从注释样式中选择Gson
按预览

这将为您提供反序列化json响应所需的所有pojos。您还需要在gradle文件中导入gson，在依赖项中添加以下行：

compile 'com.google.code.gson:gson:2.6.2'

尝试这种方式：

 private void getResponseList() {
    ApiInterface apiService = ApiClient.getClient().create(ApiInterface.class);
    Call<Example> call = apiService.getResponse();
    call.enqueue(new Callback<Example>() {
        @Override
        public void onResponse(@NonNull Call<Example> call, @NonNull Response<Example> response) {
            assert response.body() != null;
            Log.e("Message",""+response.body().getMessage());
            Log.e("Code",""+response.body().getCode());
            Log.e("DisplayName",""+response.body().getDealsViewModel().getCountryDealsViewModel().getDealsPageInfo().get(0).getExpiredDate());
        }

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