[JAVA] Fall when animating a View containing an Android Recycler View with Transition

It's a little jammed, so it's a memo.

When the RecyclerView was scrolling and the parent View animation ran in Transition, it crashed.

java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

It seems that the same View will be added if the animation runs while scrolling.

The problem was solved by excluding the RecyclerView from the animation with Transition.excludeTarget (R.id.recycler_view, true).
