Should I use MapView or MapFragment

I am not sure whether I should be using MapView or stick to using a MapFragment. My application is an app that finds the nearest set of places that are closest to you. I want to be able to add locations, display details of a marker when I press a marker and when the user moves along the map I want to be able to get the coordinates of the center of the map and display the nearest locations within a defined radius. Would I be at a disadvantage if I continue to use MapFragments or should I switch over to MapView while I still have the chance?
