Getting exception when clicked on HelloItemizedOverlay

Postby man4And » Sat Aug 15, 2009 6:41 am

Hi friends
I am showing some locations in the map, when i click on the particulat overlay, i am planning to show a dialog box to show the details info of that particular overlay.
The detailed info of overlay is there in my locations in Mylocations.java .
So onTap, i am calling a method in Mylocations.java and starting a new intent which will show a new layout with all detailed info.

I am getting below issue, can you please help me?

public class Mylocations extends MapActivity {

private static List<LocationInfo> locations;
@Override
public void onCreate(Bundle savedInstanceState) {
------------------
------------------
itemizedOverlay = new HelloItemizedOverlay(this, drawable);
------------------
------------------
}

----------------
----------------
public void showDetailedInfo(Context mContext, int index){
Intent intent = new Intent(mContext, ShowDetailedtInfo.class);
startActivity(intent);
}
----------------
----------------

}

public class HelloItemizedOverlay extends ItemizedOverlay {

public HelloItemizedOverlay(Context context, Drawable defaultMarker) {
super(boundCenterBottom(defaultMarker));
mContext = context;
}
@Override
protected boolean onTap(int index) {
Mylocations mylocations = new Mylocations();
mylocations .showDetailedInfo(mContext,index);
}

}

When starting new activity @ startActivity(intent);, i am getting the below error:

08-13 23:30:03.758: WARN/dalvikvm(1528): threadid=3: thread exiting with uncaught exception (group=0x4000fe70)
