SpatialReference mSR4326 = SpatialReference.create(4326);
SpatialReference mSR3857 = SpatialReference.create(3857);
1. 屏幕坐标转换成投影坐标
@Override
public boolean onSingleTap(MotionEvent point) {
SpatialReference sr = map.getSpatialReference();
Point dp = map.toMapPoint(point.getX(), point.getY());
}
2. 投影坐标转换成经纬度
Point wgsPoint = (Point) GeometryEngine.project(dp ,map.getSpatialReference(),mSR3857);
3、经纬度转换成投影坐标
Point mapPoint = (Point) GeometryEngine.project(wgsPoint ,mSR4326,map.getSpatialReference());
4、投影坐标转换成屏幕坐标
Point screenPoint = map.toScreenPoint(mapPoint);
