android - how to LoopJ AndroidAsyncHttp with retry dialog -

i try extends asynchttpclient 1 boolean argument on true show dialog , retry connection don't how can access user sent asynchttpresponsehandler onfailure event, , can't show retry dialog

so retry extends asynchttpresponsehandler this:

import org.apache.http.header;  import android.graphics.color; import android.graphics.drawable.colordrawable; import android.view.view; import android.view.view.onclicklistener;  import com.loopj.android.http.asynchttpclient; import com.loopj.android.http.asynchttpresponsehandler;  public class cuasynchttpresponsehandler extends asynchttpresponsehandler {      private cuactivity activity;     private boolean retry;     private cuasynchttpresponsehandler response;       public void cuasynchttpresponsehandler(cuactivity activity) {         this.activity = activity;         this.retry = false;         this.response = this;      }      public cuasynchttpresponsehandler(cuactivity activity, boolean retry) {         this.activity = activity;         this.retry = retry;         this.response = this;      }       public void onfailure(int statuscode, header[] headers,             byte[] errorresponse, throwable e) {         if (this.retry == true) {             final cudialogretry cdd = new cudialogretry(activity, null, true);             cdd.getwindow().setbackgrounddrawable(                     new colordrawable(color.transparent));              cdd.show();             cdd.getretrybutton().setonclicklistener(new onclicklistener() {                  @override                 public void onclick(view arg0) {                      response.onstart();                     cdd.dismiss();                  }              });         }      }      @override     public void onsuccess(int arg0, header[] arg1, byte[] arg2) {      } } 

but onstart don't restart request(because response , don't have access retry client send request
