我如何在ConstraintLayout中重叠组件？

Question

我正在尝试在约束布局内重叠组件。我想让Team One的底部位于vs容器的顶部。我可以使用app:layout_constraintVertical_bias属性将其对齐。键盘展开时，组件没有响应。它将Team One推到vs上方，使其与vs容器的顶部齐平。

我还不能对最初的帖子做简单的评论。

但是您的team_one_color_picker视图似乎设置为200的高度，这使父视图无法正确显示在可用屏幕中。尝试将高度参数更改为动态参数

也因为team_one_name_container对象的顶部和底部受到限制，所以其高度可以为0dp。
