Android Studio布局预览未显示设计 [英] Android Studio Layout preview not showing design

问题描述

我目前正在一个项目上，一切都很好.今天，当我打开android studio时，设计/布局预览仅显示白屏. (就像图片一样)

I am currently working on a project and everything was fine. Today, while I opened android studio, the design/layout preview showing white screen only. (Like the picture)

我确实尝试过:

1. 使缓存无效并重新启动
2. 强制布局刷新
3. 将appcombat降级到27.1.1
4. 在style.xml中添加Base.Theme

但是，没有任何效果. 没有构建错误，可以在模拟器中正常运行，并且可以在模拟器中进行设计显示，但不能在android studio中运行.

But, nothing worked. No Build errors, runs fine in emulator and design shows in emulator, but not in android studio.

任何解决方案都会有很大帮助，如果您需要更多详细信息，也请告诉我.

Any solution would be a great help, also let me know if you need more details.

即使具有Hello World布局的新项目也显示相同.尝试过，卸载并安装Android Studio.

Even a new project with Hello World layout appears same. Tried, uninstalling and installing Android Studio.
