Android网络状态监听

最近发现自己的项目中没有主动监测网络状态的功能，都是被动掉线！所以在网上找了些资料实现了下！这里写下来，方便以后自己翻看，也方便大家学习指导！
本DOME中设计到了3方面的知识（这些具体知识介绍博客园有很多，这里不多介绍）
1.service（服务）
2.Receiver（广播）
3.Timer（计时器线程）
接下来直接上代码了！
1.创建一个接口保存网络状态

public interface GetConnectState {public void GetState(boolean isConnected);}

@Overridepublic void onCreate() {// TODO Auto-generated method stubsuper.onCreate();//注册广播this.mReceiver = new ConnectReceiver();IntentFilter intentFilter = new IntentFilter();intentFilter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);registerReceiver(mReceiver, intentFilter);}/*** 广播，将服务接收到的数据传到界面* @author WJD**/public class ConnectReceiver extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent intent) {// TODO Auto-generated method stubif (intent.getAction().equals(ConnectivityManager.CONNECTIVITY_ACTION)) {Timer timer = new Timer();timer.schedule(new QunXTask(), new Date());}}}/*** 定时器线程* * @author WJD* */class QunXTask extends TimerTask {@Overridepublic void run() {// TODO Auto-generated method stubif (isNetConnect()) {isConnected = true;} else {isConnected = false;}//设置连接状态if (onGetConnectState != null) {onGetConnectState.GetState(isConnected);}}}

/*** 判断是否有网络* @return*/private boolean isNetConnect() {//初始化网络管理器ConnectivityManager conMag = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE);if (conMag == null) {return false;} else {//获取所有的网络连接，包括wifi，和移动网NetworkInfo[] infos = conMag.getAllNetworkInfo();if (infos != null) {for (int i = 0; i < infos.length; i++) {//判断是否处于连接状态if (infos[i].getState() == NetworkInfo.State.CONNECTED) {return true;}}}}return false;}

Intent intent = new Intent();
intent.setClass(this, NetWrorkServer.class);
bindService(intent, serviceConnection, Context.BIND_AUTO_CREATE);

/*** 网络状态监听事件*/private ServiceConnection serviceConnection = new ServiceConnection() {@Overridepublic void onServiceDisconnected(ComponentName name) {// TODO Auto-generated method stub}@Overridepublic void onServiceConnected(ComponentName name, IBinder service) {// TODO Auto-generated method stubmNetWrorkServer = ((NetWrorkServer.MyBinder) service).getServer();mNetWrorkServer.setOnGetConnectState(new GetConnectState() {@Overridepublic void GetState(boolean isConnected) {// TODO Auto-generated method stubif (isConnected) {mHandler.sendEmptyMessage(1);} else {mHandler.sendEmptyMessage(0);}}});}};

class MyHandler extends Handler {@Overridepublic void handleMessage(Message msg) {// TODO Auto-generated method stubsuper.handleMessage(msg);switch (msg.what) {case 0:text_mob.setText("网络连接失败");break;case 1:text_mob.setText("网络连接成功");break;default:break;}}}

@Overrideprotected void onDestroy() {// TODO Auto-generated method stubsuper.onDestroy();if (mNetWrorkServer != null) {unbindService(serviceConnection);}}

希望有大牛指导，提供更强劲的思路！！！
