Description
int firstPosition = linearLayoutManager.findFirstVisibleItemPosition();
int lastPosition = linearLayoutManager.findLastVisibleItemPosition();
init，the firstPosition and lastPosition equals -1.
recyclerView.getLayoutManager().getChildAt(0) and recyclerView.getLayoutManager().getChildAt(1) are empty.Because I want to realize that the first position child is normal and the second child is half transparent.But I never get the childAt 1. Thank you!

Research direction
Start by reproducing the initialization state described with LinearLayoutManager, including findFirstVisibleItemPosition(), findLastVisibleItemPosition(), and getChildAt(). Inspect the RecyclerViewPager implementation and determine whether the reported empty children are expected before layout. Done should include a clearly defined behavior for accessing the first and second visible children.
