c# - Android.Views.InflateException: Binary XML file line #1: Error inflating Class BottomNavigationView

问题描述

我试图将 Toolbar、TabBarLayout 和 BottomNavigationView 添加到我的活动中。不添加工具栏，一切正常，但添加工具栏后，应用程序崩溃并出现错误：

Android.Views.InflateException: Binary XML file line #1: Binary XML file line #1: Error inflating class android.support.design.widget.BottomNavigationView

我正在使用线性布局。我尝试通过更改 layout_weight 和主题以及我可以在 stackoverflow 上找到或通过搜索 Google 找到的所有其他方法，但找不到解决方案。我正在分享我的布局、样式和活动代码。
