推荐答案

我发现只要我没有查看项目级别的build.gradle文件，选择构建变体"菜单项就变得可用.在编辑项目级别的build.gradle文件时，菜单选项显示为灰色.但是，如果我打开另一个文件，例如模块级的build.gradle文件，则选择构建变体"菜单项将变为可用.

I found that the "Select Build Variant" menu item became available as long as I wasn't viewing the project-level build.gradle file. While editing the project-level build.gradle file, the menu option was grayed out. But if I opened a different file, for example a module-level build.gradle file, the "Select Build Variant" menu item became available.
