animateLayoutChanges does not work well with nested layout?

Question

I have a nested layout like the following:

Answer 1

As a Kotlin Extension

fun ViewGroup.forceLayoutChanges() {
    layoutTransition.enableTransitionType(LayoutTransition.CHANGING)
}

Usage

someContainer.forceLayoutChanges()

---

Notes:

In my experience, this happens when the container is a deep nested layout. For some reason android:animateLayoutChanges="true" just doesn't work, but using this function will force it to work.
