Can you please show me or direct me to a code snippet on how does this
work?
Mine is simply not working... I haved tried:
(considering my center of the screen to be the user position that I
get from Location):
Display display =
getWindowManager().getDefaultDisplay();
int width = display.getWidth();
int height = display.getHeight();
String zoomlevel =
Integer.toString(mapView.getZoomLevel());
GeoPoint topLeft =
mapView.getProjection().fromPixels(0,
0);
GeoPoint bottomRight =
mapView.getProjection().fromPixels(width, height);
GeoPoint center = mapView.getMapCenter();
And I have tried:
int latSpan = mapView.getLatitudeSpan();
int longSpan = mapView.getLongitudeSpan();
GeoPoint mapCenter = mapView.getMapCenter();
int latitudeToEdge = mapCenter.getLatitudeE6() +
(latSpan/2);
int longitudeToTop = mapCenter.getLongitudeE6() +
(longSpan/2);
GeoPoint edgeLocation;
edgeLocation.setLatitude((float)latitudeToEdge/1E6);
edgeLocation.setLongitude((float)mapCenter.getLongitudeE6()/1E6);
topLocation.setLatitude((float)mapCenter.getLatitudeE6()/1E6);
topLocation.setLongitude((float)longitudeToTop/1E6);
centerLocation.setLatitude((float)
(mapCenter.getLatitudeE6())/1E6);
centerLocation.setLongitude((float)
(mapCenter.getLongitudeE6())/1E6);
I guess I have no mathematical clue on how to set this :S
