利用Linkify类的addLinks方法加入正则表达式。以网址为例

  String scheme = "http://";
  Linkify.addLinks(spanableInfo_temp,
                Pattern.compile("http://[a-zA-Z0-9+&@#/%?=~_\\-|!:,\\.;]*[a-zA-Z0-9+&@#/%=~_|]"),
                scheme);

SpannableStringBuilder的setSpan方法设置点击效果

 URLSpan[] urlSpans = spanableInfo_temp.getSpans(0, spanableInfo_temp.length(),
                URLSpan.class);
        for (URLSpan urlSpan : urlSpans) {
            int start = spanableInfo_temp.getSpanStart(urlSpan);
            int end = spanableInfo_temp.getSpanEnd(urlSpan);

            spanableInfo.setSpan(new Clickable(c, urlSpan.getURL(), color,mOnClickString), start, end,
                    Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

        }

设置点击文字监听

textView.setMovementMethod(new LinkTouchMovementMethod());

使用方式

 SpannableString s = new SpannableString("hello my name is @ldoublem,my phone is 13511111111 and 05718888888," +
                "\nmy Sina Blog is https://weibo.com/u/1791039083 " +
                "\n这是个话题" +
                "#hello world#" +
                ""+"#你好# #世界#");
 TextUrlUtil.dealContent(s, tv_text, R.color.colorPrimaryDark, new TextUrlUtil.OnClickString() {
            @Override
            public void OnClick(String s) {
                //  处理不同的点击操作
            }
        });
