英文:
Round corners for BottomSheet expanded?
问题
以下是您要翻译的内容：
"Out of curiosity, what needs to be done that the damn bottom sheet actually keeps its rounded corners in expanded state?
Im struggling the whole day with that issue, i have a bottomsheet defined in XML, material design 1.9 and it still flattens them. Are there any files that require a replacement?

What am i doing wrong here? Is there a way to make a BottomSheet keep its round corners once expanded?"

底部表单不能有底部圆角。这在开发者方面引起了很大的争议。圆角表明有可滚动的文本，因此他们只允许顶部是圆角的。
参见此链接：https://github.com/material-components/material-components-android/pull/437#issuecomment-536668983
因此，除非他们决定让我们覆盖该方法，否则我们将永远只能使用顶部圆角。
英文:
The bottom sheet can not have bottom corners. This was a big debate on the developers side. The rounded corners indicated that there was scrollable text. So they only allow for the top to be rounded.
See this: https://github.com/material-components/material-components-android/pull/437#issuecomment-536668983
So we are forever stuck with only top round corners unless they decide to let us override the method.
