实现方案：
我们直接参考实例代码：
private String pattern = "((http|ftp|https)://)(([a-zA-Z0-9\\._-]+\\.[a-zA-Z]{2,6})|([0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}))(:[0-9]{1,4})*(/[a-zA-Z0-9\\&%_\\./-~-]*)?|(([a-zA-Z0-9\\._-]+\\.[a-zA-Z]{2,6})|([0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}))(:[0-9]{1,4})*(/[a-zA-Z0-9\\&%_\\./-~-]*)?";Pattern r = Pattern.compile(pattern);Matcher m;mTv.setText(identifyUrl(richURL.msg));public SpannableStringBuilderForAllvers identifyUrl(CharSequence text) { CharSequence contextText; CharSequence clickText; text = text == null ? "" : text; //以下用于拼接本来存在的spanText SpannableStringBuilderForAllvers span = new SpannableStringBuilderForAllvers(text); ClickableSpan[] clickableSpans = span.getSpans(0, text.length(), ClickableSpan.class);

//可点击文本 clickText = text.subSequence(start, end); } else { contextText = text; clickText = null; } m = r.matcher(contextText); //匹配成功 while (m.find()) { //得到网址数m.group() if (m.start() < m.end()) { span.setSpan(new LinkClickSpan(m.group(), m.group(), mUrlSpanClickListener), m.start(), m.end(), Spanned.SPAN_INCLUSIVE_EXCLUSIVE);
