推荐答案

这是一个博客发布，其中讨论了ConstraintLayout中的负边距.

Here is a blog posting that discusses negative margins in ConstraintLayout.

使用空格作为负边距

ConstraintLayout中的视图的边距不能为负(不支持).但是，通过一个简单的技巧，您可以通过插入一个Space(本质上是一个空View)并将其大小设置为所需的边距来实现类似的功能.

A view in a ConstraintLayout cannot have negative margins (it’s not supported). However, with an easy trick you can have similar functionality by inserting a Space (which is essentially an empty View) and setting its size to the margin you want.
