.setInterpolator(new AccelerateInterpolator())
.build();
CardStackLayoutManager.setSwipeAnimationSetting(setting);
CardStackView.swipe();

RewindAnimationSetting setting = new RewindAnimationSetting .Builder ()
.setDirection (Direction .Bottom )

Paging
You can implement paging by using following two ways.
Use DiffUtil .
Call RecyclerView.Adapter.notifyItemRangeInserted manually.

You can implement reloading by calling RecyclerView.Adapter.notifyDataSetChanged
.
