I already extended SherlockMapActivity,which is a compatibilty library that allows tabbed like interface found in later versions of android.. The Problem is I have two Tabs. A Mapview Tab and a ListView Tab.The MapView works fine but the List View doesnt.I want a way to implement an expandablelistview without extending the expandablelistactivity..The Expandablelistview should appear under the listview tab.
The problem now is that the setListAdapter method is undefined in my Code..pls help.

```
public class MainActivity extends SherlockMapActivity implements LocationListener,ActionBar.TabListener {

private MapController mapController;
private MapView mapView;    
private LocationManager locationManager;
private GeoPoint currentPoint;
private Location currentLocation = null;
private PlaceOverlay currPos;
private ViewSwitcher tswitcher;

public boolean showMiniHelp = true;

TableLayout tlayout;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
    setContentView(R.layout.activity_main);

    tswitcher = (ViewSwitcher)findViewById(R.id.viewSwitcher1);

    getSupportActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
    ActionBar.Tab tab1 = getSupportActionBar().newTab();
    tab1.setText("Map View");
    tab1.setTabListener(this);
    getSupportActionBar().addTab(tab1);

    ActionBar.Tab tab2 = getSupportActionBar().newTab();
    tab2.setText("List View");
    tab2.setTabListener(this);
    getSupportActionBar().addTab(tab2);

    mapView = (MapView)findViewById(R.id.mapView);
    mapView.setBuiltInZoomControls(true);
    mapView.setSatellite(false);      
    mapController = mapView.getController();
    mapController.setZoom(17);
    getLastLocation();
    drawCurrPositionOverlay();
    drawStores();
    drawSportLocations();
    animateToCurrentLocation();
