issue in JSON parsing by GSON - json

Question

I have Issue in JSON Parsing by GSON
my JSONERESPONSE is
{"services":[{"service":{"name":"asd","id":"1"}},
{"service":{"name":"asdf","id":"2"}},
{"service":{"name":"asdfg","id":"3"}}]}
How to parse this response?
means I have issue in creating class of above response
I have created service class but i am confusing in how to create services class.
public class services {
#SerializedName("service")
ArrayList<service> list;
public services(){
System.out.println("services constructor stuff");
list= new ArrayList<service>();
}
/**
* #return the list
*/
public ArrayList<service> getList() {
return list;
}
/**
* #param list the list to set
*/
public void setList(ArrayList<service> list) {
this.list = list;
}
}
but getting 0 in getList();
Note: I can not change the response, so don't suggest it
Thank you

Ok, we need to create a middle layer class to make it right.
Services.java
public class Services {
private ArrayList<ServiceWrapper> services = new ArrayList<ServiceWrapper>();
public ArrayList<ServiceWrapper> getServices() {
return services;
}
public void setServices(ArrayList<ServiceWrapper> services) {
this.services = services;
}
}
ServiceWrapper.java
public class ServiceWrapper {
private Service service;
public Service getService() {
return service;
}
public void setService(Service service) {
this.service = service;
}
}
Service.java
public class Service {
private int id;
private String name;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
The following is testing code
Gson gson = new Gson();
String s = "{\"services\":[{\"service\":{\"name\":\"asd\",\"id\":\"1\"}},{\"service\":{\"name\":\"asdf\",\"id\":\"2\"}},{\"service\":{\"name\":\"asdfg\",\"id\":\"3\"}}]}";
Services services = gson.fromJson(s, Services.class);
for(ServiceWrapper serviceWrapper : services.getServices()){
System.out.println(serviceWrapper.getService().getId());
System.out.println(serviceWrapper.getService().getName());
}

Services.java
public class Services {
private List<Service> services;
public List<Service> getServiceList() {
return services;
}
public void setServiceList(List<Service> services) {
this.services = services;
}
}
Service.java
public class Service {
private int id;
private String name;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
your json parsing logic goes here:
Gson gson = new Gson();
String s = "{\"services\":[{\"service\":{\"name\":\"asd\",\"id\":\"1\"}},{\"service\":{\"name\":\"asdf\",\"id\":\"2\"}},{\"service\":{\"name\":\"asdfg\",\"id\":\"3\"}}]}";
Services services = gson.fromJson(s, Services.class);
Basically, the json string is not a simple json array format, it is actually a json array inside a json object. So it implies that you need two Class, one represents each item inside json array - Service.java and another plays as a wrapper holding a list of items.
