Answer 1

I think you have to use

mapview.getProjection().frompixel(intx, int y)

For the 4 corners of your screen (you can get their coordinates by getwidth and getheight on your mapView, and starting with (0,0), (getwidth(),0), (0,getheight()) and (getwidth(), getheight())

This will give you 4 geopoints from which you can extract latitude and longitude
