My function for make multiple links inside TextView

fun TextView.makeLinks(vararg links: Pair) {
    val spannableString = SpannableString(this.text)
    for (link in links) {
        val clickableSpan = object : ClickableSpan() {

            override fun updateDrawState(textPaint: TextPaint) {
                 // use this to change the link color
                 textPaint.color = textPaint.linkColor
                 // toggle below value to enable/disable
                 // the underline shown below the clickable text
                 textPaint.isUnderlineText = true
            }

            override fun onClick(view: View) {
                Selection.setSelection((view as TextView).text as Spannable, 0)
                view.invalidate()
                link.second.onClick(view)
            }
        }
        val startIndexOfLink = this.text.toString().indexOf(link.first)
        spannableString.setSpan(clickableSpan, startIndexOfLink, startIndexOfLink + link.first.length,
                Spanned.SPAN_EXCLUSIVE_EXCLUSIVE)
    }
    this.movementMethod = LinkMovementMethod.getInstance() // without LinkMovementMethod, link can not click
    this.setText(spannableString, TextView.BufferType.SPANNABLE)
}
