试试下面的代码,

public class ConnectionAvailable extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {

    ConnectivityManager manager = (ConnectivityManager) context
            .getSystemService(context.CONNECTIVITY_SERVICE);
    boolean is3g = manager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE)
            .isConnectedOrConnecting();
    boolean isWifi = manager.getNetworkInfo(ConnectivityManager.TYPE_WIFI)
            .isConnectedOrConnecting();

    if (!is3g && !isWifi) {

        Toast.makeText(context, "Internet Connection Lost",
                Toast.LENGTH_LONG).show();

    } else {
        if ((intent.getAction() != null)
                && (intent.getAction()
                        .equals("android.intent.action.AIRPLANE_MODE"))) {
            Toast.makeText(context, "Internet Connection Lost",
                    Toast.LENGTH_LONG).show();               
        }
    }
}
}
