Android: making overlay images clickable

I hope someone can help with this. I have created a map app that puts an icon on locations from an xml file, but I need to make the icons clickable to open a page of info about the location.

At present I have this under the class GPSLocationListener implements LocationListener:

MapOverlay mapOverlay = new MapOverlay();
mapOverlay.setPointToDraw(point, "pointer", null);

List<Overlay> listOfOverLays = mapView.getOverlays();
listOfOverLays.clear();

// doc is data from xml file                
NodeList nodes = doc.getElementsByTagName("result");

listOfOverLays.add(mapOverlay);

for (int i = 0; i < nodes.getLength(); i++) {                       

    Element e = (Element)nodes.item(i);

    String locId = XMLfunctions.getValue(e, "id");
    String aString = XMLfunctions.getValue(e, "lat");
    double lat = Double.parseDouble(aString);
    String bString = XMLfunctions.getValue(e, "long");
    double longi = Double.parseDouble(bString);


    // here, 'point' and mapOverlay have already been created and added                                 
    GeoPoint point2 = new GeoPoint((int) (lat * 1E6), (int) (longi * 1E6));
    MapOverlay mapOverlay2 = new MapOverlay();
    mapOverlay2.setPointToDraw(point2, "place", XMLfunctions.getValue(e, "name"));
    OverlayItem item = new OverlayItem(point2, "", "");
    listOfOverLays.add(mapOverlay2);
    }   

Outside of this class I have a class to create the location icons and assign the location names:

class MapOverlay extends Overlay{
    private GeoPoint pointToDraw;
    private String pointerIcon;
    private String locName;

    public void setPointToDraw(GeoPoint point, String pointer, String locationName){
        pointToDraw = point;
        pointerIcon = pointer;
        locName = locationName;
    }

    @Override
    public boolean draw(Canvas canvas, MapView mapView, boolean shadow, long when){
        super.draw(canvas, mapView, shadow);

        // convert point to pixels
        Point screenPts = new Point();

        mapView.getProjection().toPixels(pointToDraw, screenPts);

        // add marker
        if(pointerIcon == "pointer"){

            Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.pointer);
            canvas.drawBitmap(bmp, screenPts.x, screenPts.y - 22, null);
        }
        else if(pointerIcon == "bar"){
            Bitmap bmp = BitmapFactor开发者_如何学Cy.decodeResource(getResources(), R.drawable.pointer2);
            canvas.drawBitmap(bmp, screenPts.x, screenPts.y - 15, null);
            Paint paint = new Paint();
            paint.setColor(Color.BLACK);
            paint.setTextSize(20);
            canvas.drawText(locName, screenPts.x, screenPts.y-20, paint);
        }

        return true;
    }
}

I just need to make the image 'pointer2' clickable and open a new page with the 'locId', so that I know which location has been clicked. I have read alot online about doing this, but nothing has worked. Any information that can get me closer to making this work it greatly appreciated.

Sorted it, but pretty much had to start from scratch and use Itemised Overlay. Here is what I referenced: http://blog.chrisblunt.com/android-map-view-double-taps-and-overlay-markers/
