Android-监测网络是否能够使用的代码

public class NetworkUtils {
    public static boolean isNetworkConneted(Context paramContext) {
        boolean b = false;
        if (paramContext != null) {
            NetworkInfo localNetworkInfo = ((ConnectivityManager) paramContext.getSystemService(Context.CONNECTIVITY_SERVICE)).getActiveNetworkInfo();
            if (localNetworkInfo != null) {
                b = localNetworkInfo.isAvailable();
            }
        }
        return b;
    }

    public static boolean isWifiConnected(Context paramContext) {
        boolean b = false;
        NetworkInfo localNetworkInfo = ((ConnectivityManager) paramContext.getSystemService(Context.CONNECTIVITY_SERVICE)).getActiveNetworkInfo();
        if ((localNetworkInfo != null) && (localNetworkInfo.getType() == ConnectivityManager.TYPE_WIFI)) {
            b = true;
        }
        return b;
    }
}
