How can I make a gps blue dot like in iPhone GPS?

I’m developing for android, and I want to just have a map with like a GPS dot in my application. How can I do this? I’m not really sure how would I position the map, so that the GPS dot shows up at the right place? Also, how can I have the dot move while I am moving?
