Changes in the theme editor doesn't update project?

Question

so I am running the latest version of android studio, and I am a bit confused about how the theme editor works. I have selected a different theme from the options, but android studio isn't updating everything to fit the theme. styles.xml looks the same as it was before as well as the colours used are the same. I've selected a theme with no action bar but the preview doesn't seem to have updated as well.

I was under the presumption that any changes in the theme editor will automatically update to the project, so I dont have to go to the xml code and change it all. Do I still need to do that even after using the theme editor?

预览窗口有一个刷新按钮，单击该按钮可更新并显示正确的主题。

Answer 2

该选项仅可为您提供主题的预览，不会更改代码，您只需从该选项中选择一个主题并手动进行即可，它应该可以工作
