Ok, time to ask, I've searched, tried things suggested, and have spent
a day on this to no avail. Any suggestions gratefully received. I am
using the mapview tutorial as a base and I can only get ONE marker/
location to show up - the one in Mexico, another off of Cape Cod, but
not both! (I checked the data on the locationlist array and it is
there with different lat/lons as ints)
public class LocationMapView extends MapActivity
// implements LocationListener
{
List<Overlay> mapOverlays;
Drawable drawable;
MapView mapView;
PointLocation [] locationlist ;
GeoPoint point ;
OverlayItem overlayitem ;
LocationItemizedOverlay itemizedOverlay ;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.maplayout);
mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
mapView.setStreetView(true);
LocationDb mLocationDb = new LocationDb();
mLocationDb.open();
locationlist = mLocationDb.fetchLocations() ;
mapOverlays = mapView.getOverlays();
drawable = this.getResources().getDrawable
(R.drawable.androidmarker);
point = new GeoPoint(locationlist[0].geolat, locationlist
[0].geolon) ;
overlayitem = new OverlayItem(point, "", "");
itemizedOverlay = new LocationItemizedOverlay(drawable);
itemizedOverlay.addOverlay(overlayitem);
point = new GeoPoint(locationlist[1].geolat, locationlist
[1].geolon) ;
overlayitem = new OverlayItem(point, "", "");
itemizedOverlay = new LocationItemizedOverlay(drawable);
itemizedOverlay.addOverlay(overlayitem);
mapOverlays.add(itemizedOverlay);
and ItemizedOverlay.java is-
import android.graphics.drawable.Drawable;
import com.google.android.maps.ItemizedOverlay;
import com.google.android.maps.OverlayItem;
import java.util.ArrayList;
public class LocationItemizedOverlay extends ItemizedOverlay
{
private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>
();
public LocationItemizedOverlay(Drawable defaultMarker)
{
super(boundCenterBottom(defaultMarker));
// TODO Auto-generated constructor stub
}
@Override
public int size() {
// TODO Auto-generated method stub
return mOverlays.size();
}
public void addOverlay(OverlayItem overlay) {
mOverlays.add(overlay);
populate();
}
@Override
protected OverlayItem createItem(int i)
{
return mOverlays.get(i);
}
