1、StringRequest用法

主要分为3步：

(1)、实例化一个RequestQueue对象

(2)、设置StringRequest对象参数，并将StringRequest对象加入RequestQueue队列

(3)、执行start()方法

public class StringActivity extends Activity {    private TextView mTvShow;        private RequestQueue requestQueue;        @Override    protected void onCreate(Bundle savedInstanceState) {        // TODO Auto-generated method stub        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_string);                initView();    }        public void initView(){        mTvShow = (TextView) findViewById(R.id.tv_string);                requestQueue = Volley.newRequestQueue(getBaseContext());         requestQueue.add(stringRequest);        requestQueue.start();    }        /** StringRequest请求，默认为GET*/    public StringRequest stringRequest = new StringRequest("http://www.baidu.com", new Listener
     
      () {        @Override        public void onResponse(String response) {            // TODO Auto-generated method stub            Toast.makeText(getBaseContext(), response, Toast.LENGTH_SHORT).show();        }            }, new ErrorListener(){        @Override        public void onErrorResponse(VolleyError error) {            // TODO Auto-generated method stub            Log.e("StringRequest", error.toString());        }            });        /** StringRequest的Post请求，但是需要重写匿名类getParams()*/    StringRequest stringRequest1 = new StringRequest(Method.POST, "http://www.baidu.com",  new Listener
      
       () {        @Override        public void onResponse(String response) {            // TODO Auto-generated method stub            mTvShow.setText(response);        }    }, new ErrorListener(){        @Override        public void onErrorResponse(VolleyError error) {            // TODO Auto-generated method stub            Log.e("StringRequest", error.toString());        }            }){        // 需要重写获取参数的函数,可以向服务器提交参数        protected Map
       
         getParams() throws AuthFailureError {            Map
        
          map = new HashMap
         
          ();            map.put("wd", "开始吗");            map.put("rsv_spt", "不开始啦");            return map;        };    };}
         
        
       
      
     

2、不要忘记加入网络访问权限
