Volley框架的简单用法

  String url = "";    //请求队列    RequestQueue requestQueue = Volley.newRequestQueue(this);    StringRequest stringRequest = new StringRequest(url, new Response.Listener<String>() {        //成功        @Override        public void onResponse(String response) {            Gson gson = new Gson();            gson.fromJson(response,实体类名.class);        }    }, new Response.ErrorListener() {        //失败        @Override        public void onErrorResponse(VolleyError error) {        }    });    requestQueue.add(stringRequest);}
