        new ItemBackgroundCallback() {
            private int hoverColor = Color.parseColor("#e9effb");

            @Override
            public int getDefaultBackgroundColor(@NonNull RecyclerView.ViewHolder viewHolder) {
                return Color.WHITE;
            }

            @Override
            public int getDraggingBackgroundColor(@NonNull RecyclerView.ViewHolder viewHolder) {
                return Color.WHITE;
