osmdroid - Add an area to the map

Question

I want to show touristic areas of Morocco in an osmdroid map in my Android application.

First of all, I've been searching the web for ways to get a list of coordinates (longitude & latitude) that can define an area (like an array or json), but with no luck. There are solutions for only one point on the map.

Secondly, with these coordinates, how can I show an area on osmdroid ? Thanks.

Answer 1

First I would highly recommend you to use Google Maps Api V2 through the Google Play Services. This will work much easier. Any reason why you are not using this ?

Second, to draw a polygon on the map do soemthing like

private void AddPolygon() {
    int diff=1000;

    GeoPoint pt1=new GeoPoint(13.002798, 77.580000);
    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);
}
