Answer 1

Use this method in kotlin:

private fun increaseViewSize(view: View) {
    val valueAnimator = ValueAnimator.ofInt(view.measuredHeight, view.measuredHeight+20)
    valueAnimator.duration = 500L
    valueAnimator.addUpdateListener {
        val animatedValue = valueAnimator.animatedValue as Int
        val layoutParams = view.layoutParams
        layoutParams.height = animatedValue
        view.layoutParams = layoutParams
    }
    valueAnimator.start()
}
