本文介绍两种监测Android设备网络状态变化的方法：一是通过TelephonyManager监听数据连接状态；二是使用BroadcastReceiver接收网络变化广播。

final TelephonyManager mTelephonyMgr = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);

mTelephonyMgr.listen(new PhoneStateListener(){

@Override

public void onDataConnectionStateChanged(int state) {

switch(state){

case TelephonyManager.DATA_DISCONNECTED://网络断开

Toast.makeText(NetConnectActivity.this, "DISCONNECTED", Toast.LENGTH_SHORT).show();

break;

case TelephonyManager.DATA_CONNECTING://网络正在连接

Toast.makeText(NetConnectActivity.this, "CONNECTING", Toast.LENGTH_SHORT).show();

break;

case TelephonyManager.DATA_CONNECTED://网络连接上

Toast.makeText(NetConnectActivity.this, "CONNECTED", Toast.LENGTH_SHORT).show();

break;

}

}, PhoneStateListener.LISTEN_DATA_CONNECTION_STATE);

判断网络连接的新方法

class ConnectionChangeReceiver extends BroadcastReceiver{

@Override
public void onReceive(Context arg0, Intent arg1) {
// TODO Auto-generated method stub
ConnectivityManager manager = (ConnectivityManager) arg0.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo moInfo = manager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
NetworkInfo wifiInfo = manager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
if(!moInfo.isConnected()&&!wifiInfo.isConnected()){
Toast.makeText(arg0, "duankai", 0).show();
serviceManager.stopService();

}else{
Toast.makeText(arg0, "连接", 0).show();
serviceManager.startService();
}
}

}
