android - Parse a nested json with retrofit 2.0 -

i have json's , want use retrofit parsing them.

{   "status": "true",   "data": [ {   "id": "1",   "title": "hi :)",   "text": "<p>121212</p>",   "cat_id": "1",   "username": "admin",   "coin": "0",   "datetime": "1451508880",   "isshow": "1" }, {   "id": "3",   "title": " hi :)",   "text": "hi :)",   "cat_id": "2",   "username": "hi :)",   "coin": "20",   "datetime": "1451508880",   "isshow": "1" }, {   "id": "4",   "title": "a",   "text": "sometext",   "cat_id": "1",   "username": "admin",   "coin": "10",   "datetime": "1451982292",   "isshow": "1" }   ] } 

when json in array mode code work. question how parse nested json above sample?

here javaclass: (statusclass)

public class retrostatus {  @serializedname("status") private string status;  @serializedname("data") private arraylist<retropost> data;    //getters , setters } 

(retropost class)

public class retropost {  @serializedname("id") private int id;  @serializedname("title") private string title;  @serializedname("text") private string text;  @serializedname("cat_id") private int cat_id;  @serializedname("datetime") private long datetime;    //getters , setters } 

(getpostinterface)

public interface getpost { @get("get/posts/all") call<list<retrostatus>> getpost(); } 

(and maincode)

  retrofit retrofit = new retrofit.builder()             .baseurl("http://mywebsite.it/api/")             .addconverterfactory(gsonconverterfactory.create())             .build();     getpost postservice = retrofit.create(getpost.class);     call<list<retrostatus>> call = postservice.getpost();     callback<list<retrostatus>> callback = new callback<list<retrostatus>>() {         @override         public void onresponse(response<list<retrostatus>> response, retrofit retrofit) {             if (response.issuccess()) {                 (retrostatus status : response.body()) {                     log.e("test", "nowstatusis: " + status.getstatus());                 }             } else {                 log.e("test", "failed");             }           }          @override         public void onfailure(throwable t) {             log.e("test", "onfailure");         }     };     call.enqueue(callback); 

now when run app, onfailure happend if main json in onejsonarray , use retropost parsing thats work's nice... mistake ?
sorry bad english...

root node of json not array, declared list<responsestatus> @ interface getpost. need use responsestatus instead current one. , use gettter access data

@serializedname("data") private arraylist<retropost> data; 

which array
