Heya Shane,
I've had a similar problem with gradients applied to backgrounds, what
I found the issue was, was I had didn't have the drawables in the
correct dpi folder.
While I know your not using a drawable it might be worth looking into
whether changing the AndroidManifest file to state your app handles
different screen sizes.
I don't know if this is the problem, especially considering the dialog
view working, but it might be worth a try:
// Add just underneath the Manifest tag
<supports-screens
android:largeScreens="true"
android:normalScreens="true"
android:smallScreens="true"
android:anyDensity="true" />
