推荐答案
我还没有实现 RecyclerView，但是我在线性布局中复制了两行，减去原始问题中的填充:
I have not implemented a RecyclerView, however I have replicated two rows in a linear layout, minus the padding from your original question:

试试填充，你会得到更好的结果.您也可以尝试为卡片添加背景颜色，然后您可以在您的 RelativeLayout 中去掉布局边距！
Play around with the padding and you will get better results. You can also try adding a background color to your card, then you can get rid of layout margins in your RelativeLayout!
