如何使用Paging3库在recyclerview中的每n个位置添加分隔符？

@Override
public void getItemOffsets(@NonNull Rect outRect, @NonNull View view, @NonNull RecyclerView parent, @NonNull RecyclerView.State state) {
    super.getItemOffsets(outRect, view, parent, state);
    
    int position = parent.getChildAdapterPosition(view);
    if (position % n == 0) { // n表示每n个位置添加分隔符
        outRect.bottom = dividerHeight; // 设置分隔符的高度
    } else {
        outRect.bottom = 0;
    }
}

@Override
public void onDraw(@NonNull Canvas c, @NonNull RecyclerView parent, @NonNull RecyclerView.State state) {
    super.onDraw(c, parent, state);
    
    int childCount = parent.getChildCount();
    for (int i = 0; i < childCount; i++) {
        View childView = parent.getChildAt(i);
        int position = parent.getChildAdapterPosition(childView);
        if (position % n == 0) { // n表示每n个位置添加分隔符
            float bottom = childView.getBottom();
            c.drawRect(0, bottom, parent.getWidth(), bottom + dividerHeight, dividerPaint); // 绘制分隔符
        }
    }
}

recyclerView.addItemDecoration(new YourItemDecoration());
