屏障不适用于 viewstub，填充过多
Barrier not working with viewstub, too much padding
我正在尝试将屏障与 viewstub 结合使用，从而使 textinputlayout 膨胀。问题是，当设置文本错误时（例如，用户在其中输入了错误的内容），填充会变得一团糟。我会提供代码和截图。
Viewstub 用法

自动添加 200dp 填充（来自布局检查器的值）
解决这个问题的唯一办法就是不再使用障碍，但我想继续使用它们
好的，我已经设法解决了这个问题。我不得不从 viewstub_inflated_layout 中删除 constraintlayout。这是解决方案
