为什么我的应用程序不会膨胀导航视图类？

Question

我一直在为我的家庭活动制作抽屉菜单，但每次我尝试运行它时，它总是显示此异常：

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.rplgdc.rekrutmenrpl/com.rplgdc.rekrutmenrpl.Activity.HomeActivity}: android.view.InflateException: Binary XML file line #22: Error inflating class android.support.design.widget.NavigationView

我一直在阅读以前的帖子，主要是由于 appcompat 和 gradle 中的设计库不匹配造成的。但是我检查了我的，它是一个和另一个匹配的。

这是我拥有的一些代码。

activity_home.xml 文件

它看起来像在文件 activity_home.xml 中您引用的是同一个文件。尝试删除以下行并尝试构建应用程序：

<include layout="@layout/activity_home"/>
