如何从网页视图中的长点击链接获取 URL？

Question

我想在 android 中为 web 视图创建一个上下文菜单。我的问题是我无法从点击的链接中获取 URL。我写这段代码来记录点击的链接：

webView.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(final View v) {

            WebView webView1 = (WebView) v;
            WebView.HitTestResult hitTestResult = webView1.getHitTestResult();
            Log.i("LinkClicked", hitTestResult.getExtra());

            return false;
        }
    });

使用此代码，当长按 stackoverflow 等网站中的链接时，日志如下：

https://stackoverflow.com/questions

一切正常，但是当长按谷歌搜索结果时，日志如下：

它不返回链接。我该如何解决这个问题？
