Android编程监听网络连接状态改变的方法_Android_脚本之家 这篇文章主要介绍了Android编程监听网络连接状态改变的方法,基于BroadcastReceiver实现针对网络连接状态的监听功能,需要的朋友可以参考下
本文实例讲述了Android编程监听网络连接状态改变的方法。分享给大家供大家参考，具体如下：
public class MyReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
//Toast.makeText(context, intent.getAction(), 1).show();
ConnectivityManager manager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo mobileInfo = manager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
NetworkInfo wifiInfo = manager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
NetworkInfo activeInfo = manager.getActiveNetworkInfo();
Toast.makeText(context, “mobile:”+mobileInfo.isConnected()+”\n”+”wifi:”+wifiInfo.isConnected()
+”\n”+”active:”+activeInfo.getTypeName(), 1).show();
} //如果无网络连接activeInfo为null
}
在清单文件中注册 BroadcastReceiver?
| 12345 | <receiver android:name=".MyReceiver"><intent-filter><action android:name="android.net.conn.CONNECTIVITY_CHANGE"/></intent-filter></receiver> |
<receiver android:name=”.MyReceiver”> <intent-filter> <action android:name=”android.net.conn.CONNECTIVITY_CHANGE”/> </intent-filter> </receiver>
要读取网络状态记得要加权限
复制代码 代码如下:<uses-permission android:name=”android.permission.ACCESS_NETWORK_STATE”/>
