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。 如何使用改造使用动态键 JSON 获得响应？
它与改造无关，而是gson。您正在使用 gson ( GsonConverterFactory ( 解析，而不是改造。，也许您应该为此模型注册TypeAdapter并手动执行此操作。
https://google.github.io/gson/apidocs/com/google/gson/TypeAdapter.html
您可以在下面找到另一个动态键 json 获取响应的答案

网络服务调用

response) {
Log.e("WWWWWWWWWWWWWWWWWWW",""+placeOrderModel.toString());

我得到了一个解决方案，请查看我的答案;
网络服务.java(接口(
public interface Webservices {
@POST("/******.php?request=******")
@FormUrlEncoded
void place_order(@FieldMap Map<String, String> params, Callback<Elements> callback);
}
元素.java
public class Elements{
@SerializedName("Data")
@Expose

this.Data = Data;
}
public class Data {
@SerializedName("OptionGroupName")

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

在回收器视图中为集合数据创建了一个模型
数据模型.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 + ''' +
'}';
}
}
