Drawing lines between to points on a map?

I have two 开发者_C百科markers on a map. The code is found on The developer site here. What I want to do is draw a line in between the two points. I have no idea what is to be done here. If I could get an example or tutorial site on this that would be great

-thanks

This question looks like it answers your question Drawing line between two points since the markers are set using geopoints I assume this will work for you
