android - 如何在 android 中获取网页的 html 代码？

Question

我想在android中获取网页的html代码。网页 url 将在编辑文本框中给出，然后当用户单击按钮时， TextView 将显示该网页的代码。请解释并给出代码!

如有任何帮助，我们将不胜感激!

Answer 1

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();

不要忘记在 AndroidManifest 中添加互联网权限:

<uses-permission android:name="android.permission.INTERNET" />
