Question

How can I style the blue divider between the title and the content of a Dialog (see screenshot)?

I prefer to do it via xml, but if necessary I’ll take a programmatic solution.

I’ve looked through the default styles.xml and themes.xml of android-15, but I couldn’t find anything.

If you are using ActionBarSherlock you can check it out by looking at abs_dialog_title_holo.xml. There you will see that the blue line is a devider that is defined through a view:

<View android:id="@+id/abs__titleDivider"
        android:layout_width="fill_parent"
        android:layout_height="2dip"
        android:background="@color/abs__holo_blue_light" />
