Hi,
I am trying to plot some markers on a google map.There are 2 different
marker drawables, the orange one is for the user's location and green ones
are for all other points.I have followed this source code from
CommonsWare<https://github.com/commonsguy/cw-advandroid/blob/master/Maps/ILuvNooYawk/src/com/commonsware/android/luv/NooYawk.java>.Here
is my ItemizedOverlay and OverlayItem class:
class DoItemizedOverlay extends ItemizedOverlay<CustomOverlayItem> {
>
> private ArrayList<CustomOverlayItem> items = new
> ArrayList<CustomOverlayItem>();
> Context mcontext;
> public DoItemizedOverlay(Context context,ArrayList<OverlayPoint>
> overlays)
> {
> super(null);
> mcontext=context;
> // TODO Auto-generated constructor stub
>
> for(OverlayPoint p:overlays)
> {
> CustomOverlayItem item;
> if(p.src)
> {
> item=new CustomOverlayItem(p.p,p.name, p.snippet,
> getMarker(R.drawable.src_marker), true);
> }
> else
> {
> item=new CustomOverlayItem(p.p, p.name, p.snippet,
> getMarker(R.drawable.marker), false);
> }
> items.add(item);
> //populate();
> }
> Log.d("MAPI", String.valueOf(items.size()));
> populate();
> }
>
>
>
> @Override
> public void draw(Canvas canvas, MapView mapView,
> boolean shadow) {
> super.draw(canvas, mapView, false);
>
> }
>
> @Override
> protected CustomOverlayItem createItem(int i)
> {
> return items.get(i);
> }
>
> @Override

> {
> return items.size();

class CustomOverlayItem extends OverlayItem {

I am adding the Overlay this way
> DoItemizedOverlay sourcemarker=new
> DoItemizedOverlay(ChildcareHost.mContext,OPs);
> mapView.getOverlays().add(sourcemarker);
> mapView.setBuiltInZoomControls(true);
> mapView.setStreetView(true);
> mapView.invalidate();
>
> mapView.getController().zoomToSpan(sourcemarker.getLatSpanE6(),
> sourcemarker.getLonSpanE6());
> mapView.getController().animateTo(src);

But when I run the app on an emulator I am only seeing 2 markers,the 1st
and the last one added while the log shows that there are 20 items in the
items ArrayList.What am I doing wrong? Please Help!!
