Android google maps groundoverlay

Question

In the google maps javascript api you can add a groundoverlay and just pass two points, the point lefttoplat&lefttoplong and the point rightbottomlat&rightbottomlong

Answer 1

Fixed it myself.

For everyone with the same problem, here is my code:

public class GroundOverlay extends OverlayItem {

    private MapView map;
    private Bitmap overlay;
    private GeoPoint topGeoPoint;
    private GeoPoint bottomGeoPoint;

    public Drawable drawable;

    public GroundOverlay(
            MapView map, 
            GeoPoint topLeftGeoPoint, 
            GeoPoint bottomRightGeoPoint, 
            Bitmap overlay,
            String title, 
            String snippet) {
        super(bottomRightGeoPoint, title, snippet);

        this.map = map;
        this.overlay = overlay;
        this.topGeoPoint = topLeftGeoPoint;
        this.bottomGeoPoint = bottomRightGeoPoint;

        _init();
    }

    private void _init() {
        Point topPoint = new Point();
        Point bottomPoint = new Point();

        map.getProjection().toPixels(topGeoPoint, topPoint);
        map.getProjection().toPixels(bottomGeoPoint, bottomPoint);

        int width = bottomPoint.x - topPoint.x;
        int height = bottomPoint.y - topPoint.y;

        drawable = overlayDrawable(overlay, width, height);
    }

    public BitmapDrawable overlayDrawable(Bitmap bitmap, int newWidth, int newHeight) {
        Matrix scale = new Matrix();

        float scaleFloat = (float)newWidth / (float)bitmap.getWidth();

        scale.postScale(scaleFloat, scaleFloat);
        Bitmap bitmapScaled = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), scale, false);

        BitmapDrawable bm = new BitmapDrawable(bitmapScaled);
        bm.setBounds(0,0,bitmapScaled.getWidth(),bitmapScaled.getHeight());

        return bm;
    }

}

You'll have to do the setMarker(drawable) somewhere and it should work. I'm doing that somewhere else (hence the public drawable).
