推荐答案

您可以通过寻找和版本替换 URLSpan 情况下做到这一点在code表示不要T下划线。在调用 Linkify.addLinks（），调用函数 stripUnderlines（）下面贴在你的每一个的TextView S：

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 = (Spannable)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);
    }

这需要一个定制版本URLSpan的不启用TextPaint的下划线属性：

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);
        }
    }
