Android Arcgis 100.3: How to get center Point of MapView

How to get Point from ArcGis's MapView center of the screen, which representing its latitude and longitude?

Solution 
  • float centreX=mapView.getX() + mapView.getWidth()  / 2;
float centreY=mapView.getY() + mapView.getHeight() / 2;

android.graphics.Point screenPoint = new android.graphics.Point(Math.round(centreX), Math.round(centreY));
Point mapPoint = mv.screenToLocation(screenPoint);
Point wgs84Point = (Point) GeometryEngine.project(mapPoint, SpatialReferences.getWgs84());

double lat = wgs84Point.getY();
double lng = wgs84Point.getX();
