最后，我该如何解决这个问题呢？主要原因是什么(或可能是)？
感谢您的回复。
最佳答案
我认为问题出在您的 @layout/toolbar 中，因为它在堆栈跟踪中显示 android.view.LayoutInflater.parseInclude (LayoutInflater.java:966) 。尝试检查您的工具栏 View 是否正确。
关于java - Androidx java.lang.ClassNotFoundException : and android. view.InflateException:同时，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/58105544/
