Navigation Drawer Activity Error

Question

I just updated to Android Studio 3.1.2. When i create a navigation drawer activity everything seems to work just fine. But when I go into the activity_main_drawer.xml file (menu folder) it's keep saying waiting for build to finish even after a build has already finished (even after more than 3 builds and runs on my phone). Is there any way to solve this and get a preview?

从抽屉菜单中删除这一行后，我遇到了同样的问题并解决了它： tools:showIn="navigation_view"然后我重建了项目，一切正常。
