Volley的基本使用

导入jar包

导入成功

源码

说明

应用比较灵活所以没有封装，可以根据自己的需求去进行封装

这里是启动Activity以后就开始轮询请求网络，退出以后取消请求。

添加网络权限

GET请求

package com.kongqw.kqwvolleydemo;import android.app.Activity;import android.os.Bundle;import android.util.Log;import android.widget.Toast;import com.android.volley.RequestQueue;import com.android.volley.Response;import com.android.volley.VolleyError;import com.android.volley.toolbox.StringRequest;import com.android.volley.toolbox.Volley;public class MainActivity extends Activity {
         private RequestQueue mQueue;    private StringRequest stringRequest;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        // 创建一个RequestQueue对象        mQueue = Volley.newRequestQueue(this);        // GET请求        stringRequest = new StringRequest("http://www.baidu.com",                new Response.Listener
     
      () {                    @Override                    public void onResponse(String response) {                        Log.d("TAG", response);                        Toast.makeText(MainActivity.this, "response = " + response, Toast.LENGTH_SHORT).show();                        mQueue.add(stringRequest);                    }                }, new Response.ErrorListener() {            @Override            public void onErrorResponse(VolleyError error) {                Log.e("TAG", error.getMessage(), error);                Toast.makeText(MainActivity.this, "error = " + error.getMessage(), Toast.LENGTH_SHORT).show();            }        });        mQueue.add(stringRequest);    }    @Override    protected void onStop() {        mQueue.stop();        super.onStop();    }}
     

POST请求

package com.kongqw.kqwvolleydemo;import android.app.Activity;import android.os.Bundle;import android.util.Log;import android.widget.Toast;import com.android.volley.AuthFailureError;import com.android.volley.Request;import com.android.volley.RequestQueue;import com.android.volley.Response;import com.android.volley.VolleyError;import com.android.volley.toolbox.StringRequest;import com.android.volley.toolbox.Volley;import java.util.HashMap;import java.util.Map;public class MainActivity extends Activity {    private RequestQueue mQueue;    private StringRequest stringRequest;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        // 创建一个RequestQueue对象        mQueue = Volley.newRequestQueue(this);        // POST请求        stringRequest = new StringRequest(Request.Method.POST, "http://www.baidu.com",                new Response.Listener
     
      () {                    @Override                    public void onResponse(String response) {                        Log.d("TAG", response);                        Toast.makeText(MainActivity.this, "response = " + response, Toast.LENGTH_SHORT).show();                        mQueue.add(stringRequest);                    }                }, new Response.ErrorListener() {            @Override            public void onErrorResponse(VolleyError error) {                Log.e("TAG", error.getMessage(), error);                Toast.makeText(MainActivity.this, "error = " + error.getMessage(), Toast.LENGTH_SHORT).show();            }        }) {            @Override            protected Map
      
        getParams() throws AuthFailureError {                Map
       
         map = new HashMap
        
         ();                map.put("params1", "value1");                map.put("params2", "value2");                return map;            }        };        mQueue.add(stringRequest);    }    @Override    protected void onStop() {        mQueue.stop();        super.onStop();    }}
