【问题描述】：
我在 MainActivity 中有一个片段容器视图。我有一个寄存器片段。在寄存器片段内，我有约束布局。当我在手机中启动应用程序时，寄存器片段不适合片段容器。我该如何解决这个问题？

-
即使高度指定为 match_parent，布局也可能超出其边界。在 ConstraintLayout 中，每个视图的高度（通常是
wrap_content+ 上边距 + 下边距可能会大于屏幕上可能的高度。在这种情况下，每个布局都会超出边界。有有几种方法可以解决这个问题。按照@che10 的建议添加一个滚动视图，缩小垂直边距或将所有视图放在一个垂直视图链中，该垂直视图链被限制在容器的顶部和底部。 -
