来自WebService的动态键json获取响应？

Question

下面是Web服务URL响应：

{  
 "Status":"Success",
 "StatusCode":"200",
 "Message":"data fetch successfully.",
 "Data":{  
  "1":{  
     "OptionGroupName":"OPTION",
     "OptionGroupId":"122",
     "OptionCount":2,
     "Options":[  
        {  
           "OptionGroupId":"122",
           "OptionGroupName":"Option",
           "ProductId":"2861",
           "OptionId":"329",
           "OptionName":"Hot",
           "OptionPrice":"4.00",
           "IsActive":"1"
        },
        {  
           "OptionGroupId":"122",
           "OptionGroupName":"Option",
           "ProductId":"2861",
           "OptionId":"330",
           "OptionName":"Ice",
           "OptionPrice":"4.30",
           "IsActive":"1"
        }
     ]
  }
 }
}

下面是模型类；

public class Elements{

@SerializedName("Data")
@Expose
private Map<String, Data> Data;

public Map<String, Data> getFeeds() {
    return Data;
}

public void setFeeds(Map<String, Data> Data) {
    this.Data = Data;
}

public class Data {
    @SerializedName("OptionGroupName")
    @Expose
    private String OptionGroupName;

    public String getOptionGroupName() {
        return OptionGroupName;
    }

    public void setOptionGroupName(String optionGroupName) {
        OptionGroupName = optionGroupName;
    }
}

}

下面是获取响应的代码；

  Map<String, String> jsonObject = new HashMap<>();
    jsonObject.put("productid", "2861");
    jsonObject.put("multiple", "1");

    ApiHandler.getApiService().place_order(jsonObject,
            new Callback<Elements>() {
                @RequiresApi(api = Build.VERSION_CODES.KITKAT)
                @Override
                public void success(Elements placeOrderModel, Response
                        response) {

                    Log.e("response.getElemDetails()",""+response.getBody());
                    Gson gson = new Gson();
                    Elements myObj  = gson.fromJson(response.toString(),
                            new TypeToken<Elements>(){}.getType());


                    for (int i=0;i<myObj.getFeeds().size();i++)
                    {
                        Log.e("data",""+myObj.getFeeds().get(i).getOptionGroupName());
                    }
                }

                @Override
                public void failure(RetrofitError error) {

                }
            });

我无法使用模型类解析json。如何通过改型获得动态键json的响应？

Answer 1

与翻新无关，而是gson。您正在使用gson（GsonConverterFactory）进行解析，而不是进行翻新。 ，也许您应该为此模型注册TypeAdapter并手动进行。

我有解决方案，请Plz查看我的答案；

public class Elements{

@SerializedName("Data")
@Expose
private Map<String, Data> Data;

public Map<String, Data> getFeeds() {
    return Data;
}

public void setFeeds(Map<String, Data> Data) {
    this.Data = Data;
}

public class Data {
    @SerializedName("OptionGroupName")
    @Expose
    private String OptionGroupName;

    public String getOptionGroupName() {
        return OptionGroupName;
    }

    public void setOptionGroupName(String optionGroupName) {
        OptionGroupName = optionGroupName;
    }

    @Override
    public String toString() {
        return "Data{" +
