Is there a way to implement rounded corners to a Mapfragment?

I want to give the map a nice looking rounded corners as the two boxes below it have. I can't do it with the map fragment it self because there is not a background property to a fragment. setting the map inside a layout and setting it background to a rounded shape didn't help me as well and this is the result:

I could merge the map but this would make it smaller and i would like to avoid it.

EDIT: @Ryan this is the new result #2:

I guess this is not bad, no even close to the corners on the other boxes, but still not bad with a little more work a could get somewhere close i just dont have a normal image editor. but one thing that still bothers me now is the separation between the "Location" Textview and the map it's self. could i painted the patch in other way so that there was now distance? this is how i did it:

Well I have finally figured this out:

this is what i used for the patch:

Thanks.
