final CardLinearLayoutManager linearLayoutManager = new CardLinearLayoutManager(this,
        vImg? RecyclerCardView.VERTICAL : RecyclerView.HORIZONTAL,false);
recyclerView.setLayoutManager(linearLayoutManager);

SampleCardAdapter sampleCardAdapter = new SampleCardAdapter(recyclerView,3,vImg ? 0:60)
        .setvImg(vImg)
        .setList(list);
recyclerView.setAdapter(sampleCardAdapter);

cardSnapHelper = new LinearSnapHelper();
cardSnapHelper.attachToRecyclerView(recyclerView);

CardAdapter

Constructor

public CardAdapter(RecyclerView recyclerView,int visibleCount,int minNap){
   ...
}

note:

1. visibleCount: number of visible, not support value 2.
2. minNap : min value of both padding.(left and right or top and bottom).

CardHolder

class SimpleCardHolder extends RecyclerCardView.CardHolder<CardItem> implements RecyclerCardView.OnCenterProximityListener{
    @Override
    public void onCenterPosition(boolean animate) {
        ...
    }

    @Override
    public void onNonCenterPosition(boolean animate) {
        ...

• your CardHolder can implement OnCenterProximityListener and do you animation on onCenterPosition,onNonCenterPosition.
