Android - 9 Patch

I'm trying to create a new spinner background using a 9 patch picture. I've tried many ways to get a perfect image but I failed :s Here is my 9 patch: The content looks to be good

Solution 1:

First of all, you've marked your rounded corners as stretchable, this should be avoided so your corners stay the same, no matter how its stretched. You've also marked your arrow as being stretchable vertically, which I suppose is not desirable.

See the attached image for a fixed 9-patch (note the differences in 9-patch frame compared to your image), this should scale well in all directions.
