本文给大家介绍Android 网络状态实时监听代码实例(一)，对android网络状态监听相关知识感兴趣的朋友一起学习吧
其实手机在网络方面的的监听也比较重要，有时候我们必须实时监控这个程序的实时网络状态，android在网络断开与连接的时候都会发出广播，我们通过接收系统的广播就可以实现网络的监听。
1、添加访问网络和获取网络状态的权限
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> <uses-permission android:name="android.permission.INTERNET" />
2、新建一个Application类并继承android.app.Application 申明变量保存网络状态
package com.javen.application;
import com.javen.netbroadcast.NetUtil;
public class Application extends android.app.Application {
private static Application mApplication;
public static int mNetWorkState;
public static synchronized Application getInstance() {
return mApplication;
}
@Override
public void onCreate() {
super.onCreate();
mApplication = this;
initData();
}
public void initData() {
mNetWorkState = NetUtil.getNetworkState(this);
}
}
3、新建NetBroadcastReceiver类继承BroadcastReceiver 并实现onReceive方法 在onReceive方法通知接口完成加载
package com.javen.receiver;
import java.util.ArrayList;
import com.javen.application.Application;
import com.javen.netbroadcast.NetUtil;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class NetBroadcastReceiver extends BroadcastReceiver {
public static ArrayList<netEventHandler> mListeners = new ArrayList<netEventHandler>();
private static String NET_CHANGE_ACTION = "android.net.conn.CONNECTIVITY_CHANGE";
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(NET_CHANGE_ACTION)) {
Application.mNetWorkState = NetUtil.getNetworkState(context);
if (mListeners.size() > 0)// 通知接口完成加载
for (netEventHandler handler : mListeners) {
handler.onNetChange();
}
}
}
public static abstract interface netEventHandler {
public abstract void onNetChange();
}
}
