How to set equal spacing with Android GridView?

Question

How to set the space left over to be divided equally?

For example, I have a GridView with 2 columns. The full width is 700px, and the column is 200px: how do I specify the xml, so the space left (300px) are divided evenly into 3 pieces?

i.e. 100px | 200px (Column 1) | 100px | 200px (Column 2) | 100px
