    <!-- TextView style with blue underline. It is most suitable for headers.

This is similar to ?android:attr/listSeparatorTextView but uses different
background and text color. See also android:style/Widget.Holo.TextView.ListSeparator
(which is private, so we cannot specify it as a parent style).  -->
