Android 布局预览编辑器 - 布局不可见 : java. lang.IllegalArgumentException:对象不是声明类的实例

Question

我的 Android Studio 布局编辑器没有按预期工作。在我对布局进行更改后，预览总是消失并变成一个完全白屏或卡住(我无法选择任何元素并且我对 xml 文件所做的更改不可见)。这发生在任何布局文件中。我在 invalidating chaches 并重新启动 后再次工作，但在我进行另一次更改后，我再次遇到同样的问题。执行干净构建也无济于事。

布局编辑器显示以下异常:

但是我无法理解发生了什么。我什至不确定这个错误是否是我的问题的原因。也许你能帮上忙。

注意:我使用的是 Theme.MaterialComponents.Light.NoActionBar 主题

将您的依赖项更新到 alpha09 并且它已修复:

implementation "com.google.android.material:material:1.1.0-alpha09"          // Material Components
