从谷歌地图的气球胶带上获取气球的数据

Question

当我点击标记时，我在谷歌地图中显示了纬度和经度，它会显示一个气球，上面写着画廊名称和地址 我想当我点击气球时获取画廊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"))
                {

                                 sitesList.getAddress().get(i));
                         itemizedOverlay.addOverlay(overlayItem);
        }
        }

             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);
