called onItemInCenter, the argument is the selected itemView, you can change you selected style in that method and in onBindViewHolder you can write like this to set the unselected style

       @Override
        public void onBindViewHolder(VH holder, int position) {
            Object obj = holder.itemView.getTag(R.string.tag_is_center);
            boolean selected = false;
            if (obj != null)
                selected = (Boolean)obj;
            if (!selected) {
                // the item is not in center, revert the unselected style
            }
