A little complex message layout

Question

I have a very interesting problem. I should make a layout for a text message like in telegram, but only with text. So i should shift timestamp a little bit down if text of message take more than 1 lines. I made layout with 2 textViews (one for single line message and other for multiline, you can see my layout in attach)

My problem is that when i show timestamp for multiline case all list a little jump (because height of view change) Here my code from my viewHolder (i use kotlin, but it still very obvious). The main question is - how i can calculate line count in textView before render?

   val date = stamp.toString(Constants.DEFAULT_TIME_FORMAT)
   textViewItemMessageText.text = text
   textViewItemMessageTimeForSingleLine.show()
   textViewItemMessageTime.hide()
   textViewItemMessageTimeForSingleLine.text = date
   textViewItemMessageText.post {
   if (textViewItemMessageText.lineCount > 1) {
       textViewItemMessageTimeForSingleLine.hide()
       textViewItemMessageTime.show()
       textViewItemMessageTime.text = date
   }
