android - MapActivity is not showing list -

i developing scenario in have show addresses of nearest location in listview on mapactivity. after running code list not appear on mapactivity.

here code:

public class gmapactivity extends com.google.android.maps.mapactivity implements onclicklistener{      mapview _mapview;     private static  int latitudee6 = 37985339;     private static  int longitudee6 = 23716735;
