I had similar problem - I had to do sth on a part of text clicked, but string was created at runtime. Maybe it will help someone - in this solution we do not care about finding indexStart, indexEnd in whole text (what can be quite awful) etc.:

 val action1ClickedSpan = object : ClickableSpan() {
     override fun onClick(widget: View?) {
          presenter.action1Clicked()
     }
 }

 val possibleActionsHint = SpannableStringBuilder().apply {
     val action1Start = this.length
     append(getString(R.string.action1))
     val action2Start = this.length

     append(...)
     append(...) 

     val action2Start = this.length
     append(getString(R.string.action1))
     val action2End = this.length

     setSpan(action1ClickedSpan, action1Start, action1End, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)
     setSpan(...)
 }

 this.possibleActionsTextView.apply {
     text = possibleActionsHint
     movementMethod = LinkMovementMethod.getInstance()
 }
