Brandon's right; you'll need to do custom work for now to get the blue style, which is kind of frustrating since it's peppered throughout the new design guide.
Unfortunately, you can't reference Widget.Holo.Light.TextView.ListSeparator as a parent of a custom style, because it's private.
But if you're interested in just the gray line, you can use the stock Android style inline:
style="?android:attr/listSeparatorTextViewStyle"
This will at least get you to the gray line, all caps style:
Brandon's answer will get you to the custom blue style.
FYI, if you want to subclass exactly from the current (v15) Android style for List Separators, the combined styles used in Android for Widget.TextView.ListSeparator and Widget.Holo.Light.TextView.ListSeparator that you can copy over to a new style are:
- @drawable/list_section_divider_holo_light
- true
- match_parent
- wrap_content
- bold
- ?android:textColorSecondary
- 14sp
- center_vertical
- 8dip
You'll have to copy the drawables over to your own directories though, since they're private.
