Ниже приведен URL-адрес веб-сервиса: 

{  
 "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"
        }
     ]
  }
 }
}

Ниже представлен класс модели; 

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;
    }
}

}

Ниже приведен код для получения ответа; 

  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) {

                }
            });

Я не могу разобрать json с классом модели. Как получить ответ с помощью динамического ключа JSON с помощью модернизации?

Я получил решение, пожалуйста, просмотрите мой ответ;

WebServices.java (Интерфейс) 

public interface Webservices {
@POST("/******.php?request=******")
@FormUrlEncoded
void place_order(@FieldMap Map<String, String> params, Callback<Elements> callback);
}

Elements.java 

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{" +
                "OptionGroupName='" + OptionGroupName + '\'' +
                '}';
    }

    @SerializedName("Options")
    @Expose
    ArrayList<OptionsList> Options;

    public ArrayList<OptionsList> getOptions() {
        return Options;
    }

    public void setOptions(ArrayList<OptionsList> options) {
        Options = options;
    }
}

@Override
public String toString() {
    return "Elements{" +
            "Data=" + Data +
            '}';
}

public class OptionsList {
    @SerializedName("OptionName")
    @Expose
    private String OptionName;

    public String getOptionGroupName() {
        return OptionName;
    }

    public void setOptionGroupName(String OptionName) {
        OptionName = OptionName;
    }
}
}

Создана одна модель для набора данных в Recyclerview

DataModel.java 

public class DataModel
{
String key,baseOptionGroupName,optionGroupName;

DataModel(String key,String baseOptionGroupName,String optionGroupName)
{
    this.key=key;
    this.baseOptionGroupName=baseOptionGroupName;
    this.optionGroupName=optionGroupName;
}

public String getKey() {
    return key;
}

public void setKey(String key) {
    this.key = key;
}

public String getBaseOptionGroupName() {
    return baseOptionGroupName;
}

public void setBaseOptionGroupName(String baseOptionGroupName) {
    this.baseOptionGroupName = baseOptionGroupName;
}

public String getOptionGroupName() {
    return optionGroupName;
}

public void setOptionGroupName(String optionGroupName) {
    this.optionGroupName = optionGroupName;
}

@Override
public String toString() {
    return "DataModel{" +
            "key='" + key + '\'' +
            ", baseOptionGroupName='" + baseOptionGroupName + '\'' +
            ", optionGroupName='" + optionGroupName + '\'' +
            '}';
}
}

Это не связано с модернизацией, кроме GSON.Вы анализируете с помощью gson (GsonConverterFactory), а не модифицируете.и, вероятно, вам следует зарегистрировать TypeAdapter для этой модели и сделать это вручную.
