从 TextView 中的链接中删除下划线 - Android [英] Remove underline from links in TextView - Android

问题描述

我使用两个 textview 来显示数据库中的链接，我设法更改了链接颜色，但我想删除下划线

I am using two textview to display links from database, I managed to change link colors but I want to remove the underline

email.setText(c.getString(5));
    website.setText(c.getString(6));
    Linkify.addLinks(email, Linkify.ALL);
    Linkify.addLinks(website, Linkify.ALL);

我可以从 XML 或代码中做到这一点吗?

Can I do that from XML or Code ?

推荐答案

您可以通过使用不带下划线的版本查找和替换 URLSpan 实例来在代码中完成此操作.调用 Linkify.addLinks() 后，调用下面粘贴在每个 TextView 上的函数 stripUnderlines():

You can do it in code by finding and replacing the URLSpan instances with versions that don't underline. After you call Linkify.addLinks(), call the function stripUnderlines() pasted below on each of your TextViews:

    private void stripUnderlines(TextView textView) {
        Spannable s = new SpannableString(textView.getText());
        URLSpan[] spans = s.getSpans(0, s.length(), URLSpan.class);
        for (URLSpan span: spans) {
            int start = s.getSpanStart(span);
            int end = s.getSpanEnd(span);
            s.removeSpan(span);
            span = new URLSpanNoUnderline(span.getURL());
            s.setSpan(span, start, end, 0);
        }
        textView.setText(s);
    }

这需要不启用 TextPaint 的下划线"属性的自定义版本的 URLSpan:

This requires a customized version of URLSpan which doesn't enable the TextPaint's "underline" property:

    private class URLSpanNoUnderline extends URLSpan {
        public URLSpanNoUnderline(String url) {
            super(url);
        }
        @Override public void updateDrawState(TextPaint ds) {
            super.updateDrawState(ds);
            ds.setUnderlineText(false);
        }
    }
