Question

I want to create an overlay item so if a user taps on the overlay item then a dialog with list view pops up. How do I do this?

Thanks in advance..

You need to create your own overlay by extending ItemizedOverlay. You can override the onTap() method to do whatever you want when an item is tapped.

Basic silly example:

public class CustomOverlay extends ItemizedOverlay<OverlayItem> {
    private Activity mContext;


    public CustomOverlay(Activity activity, Drawable defaultIcon) {
        super(defaultIcon);
        mContext = activity;
    }

    @Override
    protected boolean onTap(int index) {
        new AlertDialog.Builder(mContext).setItems(...
        /* Etc. - You can show the dialog here. */
    }
}
