Android 判断当前网络是否为wifi网络

public static boolean isWifiActive(Context context) {
Context context2 = context.getApplicationContext();
ConnectivityManager manager = (ConnectivityManager) context2
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo[] info;
if (manager != null) {
info = manager.getAllNetworkInfo();
if (info != null) {
for (int i = 0; i < info.length; i++) {
if ("WIFI".equals(info[i].getTypeName())
&& info[i].isConnected()) {
return true;
}
}
}
}
return false;
}
