Android layout broken with 9-patch background

Question

Hey,

I encountered this problem when updating my background to use a 9-patch image. The layout is fine on different screens using different sizes of the same image, but when I change the image to be a 9-patch it breaks the entire layout mysteriously.

The previous layout looks like this:

When changed to 9-patch:

The XML file remained the same, just the PNG files were altered.

</LinearLayout>

Any ideas? Or other solutions to get non-scaled, centered background?

Solved the problem, my padding area on the 9-patch wasn't suitable. When I drew the padding area as the inverse of the stretchable area, the image started to work. I just thought this would have been automatic if no padding area was present :)
