The root view in ReactNative is ReactRootView which onlayout is an empty method.

when call notifyDatasetChanged in RecyclerView, it's actually request layout to relayout its children. And the layout method will call super.layout to travel the whole view tree first. So that't a problem when the root view is ReactRootView.

You can manually call RecyclerView.onlayout(boolean changed, int l, int t, int r, int b) to trigger its children relayout to make notifyDatasetChanged work.
