代碼摘要：

import android.content.Context;
	import android.net.ConnectivityManager;
	import android.net.NetworkInfo;

	
	

	ConnectivityManager cm;
	cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

	boolean isWifiConnected=cm.getNetworkInfo(ConnectivityManager.TYPE_WIFI).getState() == NetworkInfo.State.CONNECTED ? true : false ;
	boolean isGprsConnected=cm.getNetworkInfo(ConnectivityManager.TYPE_MOBILE).getState() == NetworkInfo.State.CONNECTED ? true : false ;
