【中文标题】在尝试长时间无法在水平和垂直的回收器视图内的 2 个卡片视图元素之间提供空间 [重复]【英文标题】：After trying a long not able to provide space between 2 card view elements inside a recycler view for both horizontal and vertical [duplicate] 【发布时间】：2021-01-27 05:51:57 【问题描述】：我想在水平回收器视图和垂直回收器视图中的 2 张卡之间添加一些空间，但无法添加尝试过的所有内容，但无法获得溶胶，如下图所示对于水平的两张卡彼此重叠。
我在其中定义了回收站视图的 XML 代码和版本。 :-

【参考方案1】：为 CarView 布局和 ContraintLayout 内部添加边距
并将其用于您的卡。
