TextView SpannableString 使用之实现可点

这是我的 kotlin实现

 val linkWord1 = "<用户协议>"
        val linkWord2 = "<隐私说明>"
        val word = "登录表示同意XXXX${linkWord1}及$linkWord2"
        val spannableStringBuilder = SpannableStringBuilder(word)
        val index1 = word.indexOf(linkWord1)
        val index2 = word.indexOf(linkWord2)
        spannableStringBuilder.setSpan(object : ClickableSpan() {
            override  fun onClick(widget: View) {
                showXieyiDialog(userXieyiUrl ?: "")
            }

            override fun updateDrawState(ds: TextPaint) {
                super.updateDrawState(ds)
                ds.setColor(Color.parseColor("#444444"))       //设置文件颜色
                ds.setUnderlineText(false)      //设置下划线
            }
        }, index1, index1 + linkWord1.length, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)

        spannableStringBuilder.setSpan(object : ClickableSpan() {
            override fun onClick(widget: View) {
                showXieyiDialog(privateXieyiUrl ?: "")
            }

            override fun updateDrawState(ds: TextPaint) {
                super.updateDrawState(ds)
                ds.setColor(Color.parseColor("#444444"))       //设置文件颜色
                ds.setUnderlineText(false)      //设置下划线
            }
        }, index2, index2 + linkWord2.length, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)

        login_xieyi.setText(spannableStringBuilder)
        login_xieyi.setMovementMethod(LinkMovementMethod.getInstance())
