Question

我在谷歌地图上显示了纬度和经度当我点击标记它显示一个气球，其上写有图库名称和地址我想当我点击气球时获取图库名称如何实现以下是我的代码：

@Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);


    mapView = (MapView) findViewById(R.id.map);
    mapView.setBuiltInZoomControls(true);
    mapOverlays = mapView.getOverlays();
    drawable1 = getResources().getDrawable(R.drawable.greenballon);
    itemizedOverlay = new MyItemizedOverlay(drawable1, mapView);
    drawable2 = getResources().getDrawable(R.drawable.blueballon);
    itemizedOverlay2 = new MyItemizedOverlay(drawable2, mapView);
    drawable3 = getResources().getDrawable(R.drawable.redballon);
    itemizedOverlay3 = new MyItemizedOverlay(drawable3, mapView);

    for(int i=0;i<20;i++)
    {
            if(sitesList.getType().get(i).equalsIgnoreCase("Centros Culturales"))
            {

         name = sitesList.getLatitude().get(i);
         name1 = sitesList.getLongitude().get(i);
        Log.i("centos culturales lat" + i,name);
        Log.i("culturarls longitiitude"+i,name1);
        point = new GeoPoint((int) (Double.parseDouble(name) * 1E6),
                    (int) (Double.parseDouble(name1) * 1E6));
        OverlayItem overlayItem = new OverlayItem(point, sitesList.getGalleryname().get(i), 
                             sitesList.getAddress().get(i));
                     itemizedOverlay.addOverlay(overlayItem);
    }
    }
for(int i=0;i<sitesList.getLatitude().size();i++)
        {
                if(sitesList.getType().get(i).equalsIgnoreCase("Centros Culturales"))
                {

             name = sitesList.getLatitude().get(i);
             name1 = sitesList.getLongitude().get(i);
            Log.i("centos culturales lat" + i,name);
            Log.i("culturarls longitiitude"+i,name1);
            point = new GeoPoint((int) (Double.parseDouble(name) * 1E6),
                        (int) (Double.parseDouble(name1) * 1E6));
            OverlayItem overlayItem = new OverlayItem(point, sitesList.getGalleryname().get(i), 
                                 sitesList.getAddress().get(i));
                         itemizedOverlay.addOverlay(overlayItem);
        }
        }
        for(int i=0;i<sitesList.getLatitude().size();i++)

            Log.i("residencias latitute" + i,name);
             Log.i("residencias longitiitude"+i,name1);
             point3 = new GeoPoint((int) (Double.parseDouble(name) * 1E6),
                        (int) (Double.parseDouble(name1) * 1E6));
                         OverlayItem overlayItem = new OverlayItem(point3,        sitesList.getGalleryname().get(i), 
                                 sitesList.getAddress().get(i));
                         itemizedOverlay2.addOverlay(overlayItem);
        }
        }
                mapOverlays.add(itemizedOverlay);
        mapOverlays.add(itemizedOverlay2);
**//actuaaly i show lat long in google map according to "gallery type"..so here how to get data on tap of baloon...??????**
               @Override
