Android: compass + distance in a listview

I guess you have all tried "Google Places" in Maps. This is a list of POI close to you.

I really would like to do the same feature in my application with a list of GPS coordinates, but that seem really complicated.

Making the listview with the distance and the little arrow is very easy, but I cannot understand how to update this list and the arrow everytime the user move his phone.

For now I have a static listview.

I would like to know if someone succeed to create such a listview.

Thank a lot for any information.
