最后，我该如何解决这个问题？什么是（或可能是）主要原因？
感谢您的回复。
【问题讨论】：
我认为问题出在 LoginActivity @SalmanAziz 嗯，让我编辑代码。 问题已编辑。 什么是异常信息？找不到哪个类？ 向我们展示您的包含工具栏。正如它所说的android.view.LayoutInflater.parseInclude (LayoutInflater.java:966) 我认为问题出在你的@layout/toolbar
【参考方案1】：
我认为问题出在您的@layout/toolbar 上，正如您的堆栈跟踪中的android.view.LayoutInflater.parseInclude (LayoutInflater.java:966) 所说。尝试检查您的工具栏视图是否正确。
【讨论】：
问题出在land/toolbar.xml。这就是为什么我的 LG G2 和模拟器没有问题的原因。然后，你节省了我的时间！再次感谢以上是关于Androidx java.lang.ClassNotFoundException: 和 android.view.InflateException: 同时的主要内容，如果未能解决你的问题，请参考以下文章
