Android Studio预览版搞砸了，视图的边距不一致

Question

为什么Android Studio预览版与实际应用程序相比如此糟糕？其中一个视图会飞到角落，尽管在各个维度上都受到约束。

我问题的第二部分/第三部分是：为什么在我的应用程序中，第二个分隔符"分隔符2"和第一单元名称的底部之间有很大的差距？此外，为什么第二单元设置和第二除法器之间有很大的差距？过去有30像素的空白，但现在没有了，所以这不应该存在。

进一步的诊断信息：如果从元素unit2SpecialMod和unit2ShieldsUps中删除app:layout_contraintHeight_max="40dp"，则预览将看起来像实际的应用程序。

此外，第四部分，为什么在预览中，尽管视图被扔到角落里，但边距实际上是正确的，至少在你删除这一行之前是这样，为什么一旦你删除了这一行，它们就会变得不正确，就像实际应用程序中显示的那样？

屏幕截图：

这是实际应用程序的屏幕截图，你可以看到奇怪的边缘

这是安卓工作室预览的截图，你可以看到角落里奇怪的视图，这是第二单元特殊模式，"2号机组特殊模式">

这是有问题的xml文件，有点长：

Answer 1

我刚刚解决了这个问题，答案是……从除法器2中删除"app:layout_constractBottom_toTopOf="@id/unit2RaceFilter"，因为unit2RaceFilter已经对除法器2有了约束。安卓工作室似乎没有发现这一点，即使不直接输入也是不可能的。
