错误：找不到符号导入android.widget.selector；

Question

更新几个依赖项后，我的 Android Studio 构建失败并显示此错误消息。我还从使用“dataBinding{enabled = true }”切换到“viewBinding true”，我在任何地方都找不到解决方案。我已经多次尝试清理、重建、无效缓存和重新启动计算机。以前对类似问题的建议也没有解决这个问题。我是否必须启动一个新的 android studio 项目并复制我的代码？

C：\ Users \ seric \ AndroidStudioProjects \ Futlytics \ app \ build \ generated \ data_binding_base_class_source_out \ debug \ out \ com \ futlytics \ databinding \ ToggleStyleBinding.java：7：错误：找不到符号导入android.widget.selector;

我什至不使用任何称为 ToggleStyleBinding 的东西。

我的 gradle 文件如下所示：

当我不小心将 xml 放置<selector>到“layout”文件夹（而不是“drawable”）时，我遇到了这个问题。然后，Android Studio 尝试为其进行布局绑定。
