Question

所以我一直在尝试将网站的代码保存（这个网站只包含html / php），进入android内部的一个String。

现在，我已经尝试过ASyncTask，但无法让它工作。我已经阅读了整部纪录片......

我必须承认，我是Android的首发。尽管如此，出于某种原因，我尝试的所有东西要么让它崩溃，要么不起作用。

现在，我要问你一个简单的例子，如何获取网站的代码，并将其设置为字符串。

提前致谢！

我可以问你为什么要这样做吗？

HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet(url);
HttpResponse response = client.execute(request);

String html = "";
InputStream in = response.getEntity().getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
StringBuilder str = new StringBuilder();
String line = null;
while((line = reader.readLine()) != null)
{
    str.append(line);
}
in.close();
html = str.toString();

将网站的HTML代码保存到字符串Android中
