I have geojson layer in my app. It's being loaded dynamically. Basically, I need to add marker to all geojson features so I need "position".

I have loop like this :

 for (GeoJsonFeature feature : layer.getFeatures()) 
 feature.setPolygonStyle(polygonStyle); 
 

But I have no idea how to get coordinates from feature. I've tried this method :

private List<LatLng> getCoordinatesFromGeometry(Geometry geometry) 

 List<LatLng> coordinates = new ArrayList<>();

 // GeoJSON geometry types:
 // http://geojson.org/geojson-spec.html#geometry-objects

 switch (geometry.getGeometryType()) 
 case "Point":
 coordinates.add(((GeoJsonPoint) geometry).getCoordinates());
 break;
 case "MultiPoint":
 List<GeoJsonPoint> points = ((GeoJsonMultiPoint) geometry).getPoints();
 for (GeoJsonPoint point : points) 
 coordinates.add(point.getCoordinates());
 
 break;
 case "LineString":
 coordinates.addAll(((GeoJsonLineString) geometry).getCoordinates());
 break;
 case "MultiLineString":
 List<GeoJsonLineString> lines =
 ((GeoJsonMultiLineString) geometry).getLineStrings();
 for (GeoJsonLineString line : lines) 
 coordinates.addAll(line.getCoordinates());
 
 break;
 case "Polygon":
 List<? extends List<LatLng>> lists =
 ((GeoJsonPolygon) geometry).getCoordinates();
 for (List<LatLng> list : lists) 
 coordinates.addAll(list);
 
 break;
 case "MultiPolygon":
 List<GeoJsonPolygon> polygons =
 ((GeoJsonMultiPolygon) geometry).getPolygons();
 for (GeoJsonPolygon polygon : polygons) 
 for (List<LatLng> list : polygon.getCoordinates()) 
 coordinates.addAll(list);
 
 
 break;
 

 return coordinates;
 

However it doesn't seems to work. Any help, please ?
