     String url = data.blockChainUrl;        //https or http url
     SpannableStringBuilder builder = new SpannableStringBuilder("");
            int start = builder.length();
            String content = mContext.getResources().getString(R.string.block_chain_query); //填充字体颜色
            builder.append(content);
            int end = builder.length();

            builder.setSpan(new URLSpanNoUnderline(url) {
                @Override
                public void onClick(View widget) {
                    super.onClick(widget);
                }
            }, start, end, Spanned.SPAN_INCLUSIVE_INCLUSIVE);
            builder.setSpan(new ForegroundColorSpan(ContextCompat.getColor(mContext, R.color.color_a5ef44)), 0,
                    end, Spanned.SPAN_INCLUSIVE_INCLUSIVE);
            mBlockChainQuery.setText(builder);
           //必须有的set mBlockChainQuery.setMovementMethod(LinkMovementMethod.getInstance());

//自定义一个URLSpan

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