我正在尝试使用 android urlconnection 访问网页，即使使用 jsoup 解析它也成功了。但是，当我单击列表视图行时，该链接未在浏览器上打开。这是我的代码和 .xml。请帮我。

你应该称你为意图，如下所示：

Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(uri); // If you have the url, i.setData(Uri.parse(url));
startActivity(i);

让我知道你的进展。

像这样调用活动，并且 URL 必须始终以"http://" 开头，或者"https://"我使用这段代码。在某些情况下，URL 可能以"www".在这种情况下你会得到一个异常：

    String url = "http://www.example.com";
    Intent i = new Intent(Intent.ACTION_VIEW);
    i.setData(Uri.parse(url));
    startActivity(i);

您可以查看Intent.ACTION_VIEW的文档
