How can I stretch background horizontally in xml style?

Question

I'm trying to stretch vertical line in calendar_header.png horizontally as background in xml style:

<style name="CaldroidCalendarViewLayout">
    <item name="android:background">@drawable/calendar_header</item>
</style>

But it changes height of the control by height of the background. How can I solve that? I just want to fill the actual size of the control with stretched background. (It acts like background image is a part of the content - not like it's just a background.)
