改变这个

protected String doInBackground(String urls3, String result3)

到

protected String doInBackground(String... args)

然后在 doInBackground 函数中像这样声明变量

Then declare your variables like so inside your doInBackground function

String urls3 = args[0];
String result3 = args[1];

您还需要将 onPostExecute 更正为

You will also need to correct your onPostExecute to

protected void onPostExecute(String result)

和你的类声明

private class FetchWebsiteData extends AsyncTask<String, Void, String>
