我迁移到 Androidx，但迁移后，出现以下错误：
Caused by: android.view.InflateException: Binary XML file line #12: Binary XML file line #2: Error inflating class android.support.design.widget.CoordinatorLayout
Caused by: android.view.InflateException: Binary XML file line #2: Error inflating class android.support.design.widget.CoordinatorLayout
我研究了所有的资源并迁移到Androidx，但我仍然有很多问题。有人能帮我吗？我将在下面发布代码部分。
---------崩溃的开始---------
