Polygon ist nicht geschlossen

Question

Hilfe, ich versuche ein Polygon zu zeichnen, mein Polygon schließt nicht und meine Koordinaten sind korrekt. Ein letzter Punkt verbindet sich nicht mit den anderen, um das Polygon zu bilden. Ich bin mir nicht sicher, was ich falsch mache. Dank

Das Polygon wird richtig drawed. Das Problem ist in dem Punkt neue LatLng (6.524, 3.999). Wenn Sie Marker für jeden LatLng hinzufügen, können Sie ihn ansehen.

Versuchen Sie dies und hoffe, es hilft.

mMap.addMarker(new MarkerOptions().position(new LatLng(6.524, 3.999)).title("E")); 

mMap.addMarker(new MarkerOptions().position(new LatLng(6.519,3.368)).title("P01")); 
mMap.addMarker(new MarkerOptions().position(new LatLng(6.520,3.376)).title("P02")); 
mMap.addMarker(new MarkerOptions().position(new LatLng(6.522, 3.378)).title("P03")); 
mMap.addMarker(new MarkerOptions().position(new LatLng(6.523,3.382)).title("P04")); 
mMap.addMarker(new MarkerOptions().position(new LatLng(6.524,3.390)).title("P05")); 
//Point far 
mMap.addMarker(new MarkerOptions().position(new LatLng(6.524, 3.999)).title("P06")); //point far 

mMap.addMarker(new MarkerOptions().position(new LatLng(6.523, 3.406)).title("P07"));
