要解决“Android Studio主题编辑器没有做任何事情”的问题，可以尝试以下方法：

1. 清除缓存和重新启动：在Android Studio的菜单中选择“File” -> “Invalidate Caches / Restart”，然后点击“Invalidates and Restart”按钮。这将清除Android Studio的缓存并重新启动。

2. 检查插件冲突：某些插件可能与主题编辑器发生冲突，导致其无法正常工作。可以尝试禁用或卸载最近安装的插件，然后重新启动Android Studio，看看问题是否解决。

3. 更新Android Studio：确保你正在使用最新版本的Android Studio。在Android Studio的菜单中选择“Help” -> “Check for Updates”来检查是否有可用的更新。如果有可用的更新，请安装它们并重新启动Android Studio。

4. 检查主题设置：确保你正确配置了主题编辑器的设置。在Android Studio的菜单中选择“File” -> “Settings”（或“Preferences”），然后在左侧导航栏中选择“Editor” -> “Color Scheme”。确保你选择了一个有效的主题，并且“Use color scheme from the options above”选项被选中。

以下是一个示例代码，用于设置主题编辑器的主题：
