我是Android语言的新手，但我熟悉其他编程语言。今天当我想从here开始构建我的第一个应用程序时，当我使用Android Studio创建项目时，我收到此错误按摩：
Rendering Problems The following classes could not be instantiated:
- android.support.design.widget.CoordinatorLayout (Open Class, Show Exception, Clear Cache)
- android.support.design.widget.AppBarLayout (Open Class, Show Exception, Clear Cache)
Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in the IDE Exception Details java.lang.IllegalArgumentException: You need to use a Theme.AppCompat theme (or descendant) with the design library.

我尝试了其他堆栈问题中的一些解决方案，但问题没有解决。我该怎么办？
答案 0 :(得分：1)
看起来答案就在你的堆栈跟踪中：
You need to use a Theme.AppCompat theme (or descendant) with the design library.
请尝试按照此处的说明操作：
You need to use a Theme.AppCompat theme (or descendant) with this activity
