I know how to set the theme for an Application and/or Activity in Android, but I’m wondering if it’s possible to change it for an Activity using the Graphical Layout editor in Eclipse 4.2, ADT 20.0.1. No matter what I change the drop-down to, the AppTheme style from styles.xml is always used when I run the app, despite the display preview changing based on what I select. Is it currently not possible because the theme gets set in the AndroidManifest?

styles.xml:
<resources>
<style name="AppTheme" parent="android:Theme.Light" />
</resources>
The drop down box in the GUI is used to see what it looks like, if you want the theme changed then you have to edit the Android Manifest yourself
If you want to edit the theme using a drop down, in one of the tabs in the Android Manifest, I think its “Application” there is an option to change the theme and it has a list of themes.
