使用的方法

Status status = new Status();		status.setToken(token);		status.setX(x);		status.setY(y);		status.setIndex(index);		status.setPagesize(pagesize);		status.setDistance(distance);		String jsonQueryStatus = new Gson().toJson(status);				HttpUtils http = new HttpUtils();		RequestParams params = new RequestParams();		try {			params.setBodyEntity(new StringEntity(jsonQueryStatus, "utf-8"));		} catch (UnsupportedEncodingException e) {			e.printStackTrace();		}		http.send(HttpRequest.HttpMethod.GET, 				HttpGetUrl.QueryStatus(),				params, 				new RequestCallBack<Str
