Change constraint in recyclerview viewholder layout - android

I am working on chat app so I want time TextView to be like whats app it's constraint can change depend on the text

So I tried the view tree observer in the message layout and it somehow worked but there something missing

 private fun adjustTimeTextView() {

        var freeSpace: Float
        var lines: Int
        val messageViewObserver = messageView.messageLayout.viewTreeObserver
        messageViewObserver.addOnGlobalLayoutListener(object : ViewTreeObserver.OnGlobalLayoutListener {

            override fun onGlobalLayout() {

                messageView.messageLayout.viewTreeObserver.removeOnGlobalLayoutListener(this)
                val viewWidth = messageView.messageLayout.width
                Log.e("message view width", viewWidth.toString())
                val layout = messageView.messageTextTextView.layout

                if (layout != null) {
                    lines = layout.lineCount
                    Log.e("line", lines.toString())

                    val offset = layout.getLineWidth(lines - 1)

                    freeSpace = viewWidth - offset
                    if (freeSpace < 220) {
                        Log.e("minmum", "low free space")
                        val constraintSet = ConstraintSet()
                        constraintSet.clone(messageView.messageLayout)
                        constraintSet.clear(messageView.messageLayout.messageTimeTextView.id, ConstraintSet.TOP)
                        constraintSet.clear(messageView.messageLayout.messageTimeTextView.id, ConstraintSet.BOTTOM)
                        constraintSet.clear(messageView.messageLayout.messageTimeTextView.id, ConstraintSet.START)
                        constraintSet.connect(
                            messageView.messageLayout.messageTimeTextView.id,
                            ConstraintSet.TOP,
                            messageView.messageLayout.messageTextTextView.id,
                            ConstraintSet.BOTTOM
                        )
                        constraintSet.applyTo(messageView.messageLayout)

                    } else {
                        if (lines > 1) {
                            val constraintSet = ConstraintSet()
                            constraintSet.clone(messageView.messageLayout)
                            constraintSet.clear(
                                messageView.messageLayout.messageTimeTextView.id,
                                ConstraintSet.START
                            )
                            constraintSet.applyTo(messageView.messageLayout)

                        }
                    }
                }
            }

        })
    }

and here is my layout xml

<?xml version="1.0" encoding="utf-8"?>

        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.0" android:layout_marginEnd="8dp"/>

    <TextView

        android:layout_marginStart="8dp" app:layout_constraintVertical_bias="0.51"/>
</android.support.constraint.ConstraintLayout>
</android.support.constraint.ConstraintLayout>

The problem is that when I open an existing chat the constraint as first image appear didn't work as expected in the long message but as soon as I click on type a message edit text the constraint changed for the screen chat not for all chat so if i scrolled the constraints of chat on screen is unchanged unless i click on type a message edit text and so on.

am i missing listener or request focus or something else or what is missing

Here is picture one

Here is picture two

it worked by make recyclerView request layout

i added this code to recyclerview adapter

  override fun onAttachedToRecyclerView(recyclerView: RecyclerView) {
    super.onAttachedToRecyclerView(recyclerView)
    recyclerView.addOnScrollListener(object : RecyclerView.OnScrollListener(){
        override fun onScrolled(recyclerView: RecyclerView, dx: Int, dy: Int) {
            super.onScrolled(recyclerView, dx, dy)
            recyclerView.requestLayout()
        }
    })
}
