由于 Android Studio 中的折叠工具栏导致渲染问题
Render problem due to Collapsing Toolbar in Android Studio
我的布局编辑器不呈现带有折叠工具栏的布局，其他布局呈现得很好。我尝试刷新，使 cache/restart、gradle 实现无效到稳定版本，将 API 29 和 28 设置为预览而不是 30，将项目与 gradle 文件同步，切换到new/experimental 渲染引擎。到目前为止没有任何效果。问题似乎是由折叠工具栏引起的，如下面的堆栈跟踪所示。

转到文件 -> 项目结构 -> 建议 -> 找到所有相关库并更新到最稳定的版本，在我的例子中是 appcompat。中提琴！渲染引擎能够渲染布局，尽管它显示 Path.op() 是另一个问题，但它有效。
我的布局编辑器不呈现带有折叠工具栏的布局，其他布局呈现得很好。我尝试刷新，使 cache/restart、gradle 实现无效到稳定版本，将 API 29 和 28 设置为预览而不是 30，将项目与 gradle 文件同步，切换到new/experimental 渲染引擎。到目前为止没有任何效果。问题似乎是由折叠工具栏引起的，如下面的堆栈跟踪所示。
