在Drangboard 410c android开发中，在旧项目中引入android materialdesign 时 出现如下问题，有知道原因的不？

android.view.InflateException: Binary XML file line #17: Error inflating class android.support.design.internal.NavigationMenuView
Caused by: java.lang.reflect.InvocationTargetException
Caused by: android.content.res.Resources$NotFoundException: Resource is not a Drawable (color or path): TypedValue{t=0x2/d=0x7f0100c5 a=-1}
You need to use a Theme.AppCompat theme (or descendant) with this activity.

使用NavigationMenuView的Activity【一般都是mainActivity】继承自AppCompatActivity，并且修改AndroidManifest.xml中对应activity的theme，使用继承自@style/Theme.AppCompat的主题。
