Я пытаюсь выполнить следующий эффект с компоновкой координатора:
Я потратил около 30 часов +, пытаясь решить эту проблему, и я знаю, как это происходит с помощью поведения макета координатора, но есть много вещей, которые я ошибаюсь.
Вот мой xml:

Я создал подкласс поведения, чтобы попытаться анимировать сегодняшнюю метку дохода (зеленым):
class TodayEarningsLabelBehavior : CoordinatorLayout.Behavior<TextView>() {
override fun layoutDependsOn(parent: CoordinatorLayout?, child: TextView?, dependency: View?): Boolean {
return dependency is CardView
}
override fun onDependentViewChanged(parent: CoordinatorLayout?, child: TextView?, dependency: View?): Boolean {
if (child != null){
child.textSize = dependency!!.height / 3.0F
}
return false
}
}
Но как установить это поведение в xml через app:layout_behavior
в TextView $800, если он не является дочерним элементом CoordinatorLayout
?
Любой метод решения этой проблемы (который может не включать Coordinator Layout
) также приветствуется.
