If you are trying to set different background images in each RecyclerView item. Then you need to two thing in RecyclerVeiw Adapter.

Images array And
set these Images as background of CardView in onBindViewHolder method.

like this :

      public int[] images = { R.drawable.image, R.drawable.image2, R.drawable.image3, R.drawable.image4 };

        @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
            holder.cardView.setBackgroundResource(images[position % 4]);
    }

    public class LectureViewHolder extends RecyclerView.ViewHolder {
           public CardView cardView;
           cardView = itemView.findViewById(R.id.card_view);
    }

and they will be repeate after complete Images Array.
