这是我自己简单封装的volley,封装的不好哈，希望大家能多多提提意见，来让我改正！
首先下载个Volley的jar包，拷贝到libs下，同步一下代码
代码 ，注释挺详细的
创建一个Application，方便加入队列
package com.nsv.rolltv;import android.app.Application;import android.content.Context;import com.android.volley.RequestQueue;import com.android.volley.toolbox.Volley;import com.nsv.rolltv.service.LocationService;public class MyApplication extends Application { private static RequestQueue queues; public static Context mContext; @Override
public void onCreate() { super.onCreate();
mContext = this;
queues = Volley.newRequestQueue(getApplicationContext());
} public static RequestQueue getHttpQueues() { return queues;
}
}在清单文件的application标签中加入
android:name=".MyApplication"
网络请求工具类
