使用：

String url = "http://。。。。。。";XJsonRequest<List<BikeBean>> request = new XJsonRequest<>(  url, new XRequestListener<List<BikeBean>>() {@Overridepublic void onResponse(List<BikeBean> response) {Log.v("result", response.toString());}}, new ErrorListener() {@Overridepublic void onErrorResponse(VolleyError error) {Log.v("volleyerr", error.toString());}})  .setMethod(Method.GET) ;Volley.newRequestQueue(context).add(request);

百度api store获取天气信息

String httpUrl = "http://apis.baidu.com/apistore/weatherservice/citylist";String httpArg = "cityname=%E6%9C%9D%E9%98%B3";String url = httpUrl + "?" + httpArg;XJsonRequest<WeatherBean> request = new XJsonRequest<WeatherBean>( Method.GET,url, new XRequestListener<WeatherBean>() {@Overridepublic void onResponse(WeatherBean arg0) {Log.v("result", arg0.toString());}}, new ErrorListener() {@Overridepublic void onErrorResponse(VolleyError arg0) {Log.v("volleyerr", "天气。。"+arg0.toString());}}).addHeader("apikey", "0ec4ef9237be00e62fcda68c1417a28e"); Volley.newRequestQueue(context).add(request);
