我的 Android Studio 项目抛出了这个错误。它来得很突然。我不知道这是什么。
我已经尝试了所有可能的方法，但根本不起作用。它工作正常，但当我尝试在手机中测试该应用程序时突然出现这种情况。它向我展示了这个错误。我已经重建了项目并重新启动了 Android Studio 我已经尝试了互联网上所有可能的解决方案，但没有一个对我有用。

最佳答案
在此:
https://material.io/develop/android/components/bottom-app-bar/
还有这个:
https://developer.android.com/reference/com/google/android/material/bottomappbar/package-summary
没有提及 fabAttached 属性。
相反，第一个链接指出:
The FloatingActionButton can be anchored to the BottomAppBar by setting app:layout_anchor or by calling CoordinatorLayout.LayoutParams#setAnchorId(int)
所以删除这个属性:
app:fabAttached="true"
