Hello ragavendran s and 于洋 thank for your answers.
My marker image is well in the res/drawable, my geopoint is Mexico gps
coordonates (like the tuto) and the library of maps was already put in
my Manifest.
I've done what you says ragavendran s in my ItemizedOverlay class
(which i rename to NewItemizedOverlay):
import java.util.ArrayList;
import android.graphics.drawable.Drawable;
import com.google.android.maps.ItemizedOverlay;
import com.google.android.maps.OverlayItem;
@SuppressWarnings("unchecked")
public class NewItemizedOverlay extends ItemizedOverlay {
private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>
();
public NewItemizedOverlay(Drawable defaultMarker) {
super(boundCenterBottom(defaultMarker));
// TODO Auto-generated constructor stub
}
public void addOverlay(OverlayItem overlay) {
mOverlays.add(overlay);
populate();
}
@Override
protected OverlayItem createItem(int i) {
return mOverlays.get(i);
}
@Override
public int size() {
return mOverlays.size();
}
}
But i've always an error. I think the mistake is in the fourth step of
the tuto (http://developer.android.com/intl/fr/guide/tutorials/views/
hello-mapview.html) in the last part:
4. All that's left is for us to add this OverlayItem to our collection
in the HelloItemizedOverlay, and add this to the List of Overlay
objects retrieved from the MapView:
itemizedoverlay.addOverlay(overlayitem);
mapOverlays.add(itemizedoverlay);
i can't add this to the List of Overlay objects retrieved from the
MapView. How i can do that ?
Thanks
Sweet
