The basic things are:

1. A theme for your preferences activity which defines styles for the preference widgets and other things. Take a look at the first theme in themes.xml - this defines the window background, text styles and the preference styles (preferenceScreenStyle, preferenceCategoryStyle etc)
2. Some styles for each of the preference widgets (which are referenced in themes.xml). For instance in styles.xml they define the Preference.Category and Preference.PreferenceScreen styles.
3. Apply the theme to your Activity. In your manifest change your opening activity tag for your preferences activity to <activity android:theme="@style/CustomTheme"...

If you want to inherit the default Android styles and then just override some of them, then add parent="@android:style/Theme" to the opening <style... tag of your theme.
