推荐答案
我编辑了XML,因此它可能是学习如何使用ConstraintLayout的一个很好的开始.查看有关ConstraintLayout(constraintlayout.com)的教程
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ViewGroup(LinearLayout)弄乱XML
- 使用边距或填充时最好使用基于8的数字(8-16-24-32-...)
- 将CardView用于按钮是错误的,请在material.io中检查MaterialButton文档
