android - How to change app default theme to a different app theme?

Question

I have an Android app that has a default theme of Holo.Light but I want to change it to Theme.Black.I tried to do this by changing the style tag in the manifest android:theme="@style/AppTheme" to Theme.Black but it cannot be found.Is there extra steps I have to take in changing the theme?

Actually you should define your styles in res/values/styles.xml. I guess now you've got the following configuration:

<style name="AppBaseTheme" parent="android:Theme.Holo.Light"/>
<style name="AppTheme" parent="AppBaseTheme"/>

so if you want to use Theme.Black then change AppBaseTheme parent to android:Theme.Black or you could change app style directly in manifest file like this - android:theme="@android:style/Theme.Black". You must be lacking android namespace before style tag.
