Answer 1

My solution is like this. It shows hint when empty and not focused and hides if there is text or if it is touched

fun hideHint() {
        tilFloating.isHintAnimationEnabled = false
        etFloating.onFocusChangeListener = OnFocusChangeListener { v, hasFocus ->
            if ((etFloating.text != null && etFloating.text.toString() != "") || hasFocus)
                tilFloating.hint = ""
            else
                tilFloating.hint = mHint
        }
    }
