本文實例講述了Android編程監聽網絡連接狀態改變的方法。分享給大家供大家參考，具體如下：
BroadcastReceiver
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(); } //如果無網絡連接activeInfo為null}在清單文件中注冊 BroadcastReceiver
<receiver android:name=".MyReceiver"> <intent-filter> <action android:name="android.net.conn.CONNECTIVITY_CHANGE"/> </intent-filter></receiver>
要讀取網絡狀態記得要加權限
希望本文所述對大家Android程序設計有所幫助。
