Google Map API V2 - How do I keep a marker in the center of the screen while user is scrolling the map ?

This would actually be possible by overlaying a custom view on top of your map. You would write a class that extends View and you could override the draw() and onTouchEvent() methods of your view, such that it would draw (what looks like) a marker, over top of the middle of the map. When the user sets the marker, you would use a projection to translate the screen location of the marker into a LatLong on the map. You could then set a proper marker on the map (which would now be fixed to the geolocation).

As you can tell from the above, this is not the simplest process. I would suggest going with doubleA's solution, for ease of implementation.
