Android Set ImageView image src in Style

I need to set the ImageView's src within my style, but I cant find a good example of anyone doing this and when I try the below code, it crashes the app.

<ImageView android:src="@style/TitleBarImage"></ImageView>

<style name="TitleBarImage">     
    <item name="android:layout_width">wrap_content</item>     
    <item name="android:layout_height">wrap_content</item>     
    <item name="android:src">@drawable/whiteButton</item> 
</style> 

This should be simple. What gives?
