android - OSMDroid offset polygon -

i draw polygon on map using code similar :

    geopoint pt1=new geopoint(13002798,77580000);     geopoint pt2= new geopoint(pt1.getlatitudee6()+diff, pt1.getlongitudee6());     geopoint pt3= new geopoint(pt1.getlatitudee6()+diff, pt1.getlongitudee6()+diff);     geopoint pt4= new geopoint(pt1.getlatitudee6(), pt1.getlongitudee6()+diff);     geopoint pt5= new geopoint(pt1);       pathoverlay myoverlay= new pathoverlay(color.red, this);     myoverlay.getpaint().setstyle(paint.style.fill);      myoverlay.addpoint(pt1);     myoverlay.addpoint(pt2);     myoverlay.addpoint(pt3);     myoverlay.addpoint(pt4);     myoverlay.addpoint(pt5);      map.getoverlays().add(myoverlay); 

now want offset overlay polygon 10px up, independent of zoom or other parameters. how can that? need draw line above poi marker arrows.

something that:

projection pj = mapview.getprojection(); point pix = pj.topixels(p); pix.y -= 10; //10 pixels geopoint p2 = pj.frompixels(pix2.x, pix2.y); double offset = p2.getlatitude() - p.getlatitude(); 

then can offset latitude of points adding offset.

however, solution little bit strange. instead, display polygon "under" poi markers. osmdroid displays overlays following order: first @ bottom, latest on top.

latest point: never use pathoverlay filled polygons, weird behaviours in cases (when part of polygon inside view, part outside). can use osmbonuspack polygon instead.
