mbaird s answer works fine  Just be aware that there seems to be a bug in Android  2 1 at least   that if you set any individual corner s radius to 0  it forces all the corners to 0  at least that s the case with  dp  units  I didn t try it with any other units    I needed a shape where the top corners were rounded and the bottom corners were square  I got achieved this by setting the corners I wanted to be square to a value slightly larger than 0  0 1dp  This still renders as square corners  but it doesn t force the other corners to be 0 radius

Use the  lt shape gt  tag to create a drawable in XML with rounded corners    You can do other stuff with the shape tag like define a color gradient as well   Here s a copy of a XML file I m using in one of my apps to create a drawable with a white background  black border and rounded corners   lt  xml version  quot 1 0 quot  encoding  quot UTF-8 quot   gt    lt shape xmlns android  quot http   schemas android com apk res android quot  gt        lt solid android color  quot  ffffffff quot   gt                         lt stroke android width  quot 3dp quot              android color  quot  ff000000 quot    gt        lt padding android left  quot 1dp quot               android top  quot 1dp quot               android right  quot 1dp quot               android bottom  quot 1dp quot    gt                      lt corners android radius  quot 7dp quot    gt    lt  shape gt
