推荐答案
我编辑了您的 XML,因此它可能是学习如何使用 ConstraintLayout 的良好开端.查看 ConstraintLayout 教程 (constraintlayout.com)
I edited you XML so it may be a good start for learning how to use ConstraintLayout. Check a tutorial for ConstraintLayout (constraintlayout.com)
- 不要将 match_parent 与 ConstraintLayout 一起使用,我们只有 0dp (match_constraint) 和 wrap_conent
- 不要用不必要的嵌套 ViewGroups (LinearLayout) 弄乱 XML
- 使用边距或填充时最好使用基于 8 (8 - 16 - 24 - 32 - ...) 的数字
- 将 CardView 用于按钮是错误的,请查看 material.io 上的 MaterialButton 文档
