我一直试图实现同样的，这正是我想要的： -

我已经实现googleMapView与覆盖，我有一个问题，我想显示弹出每个覆盖点击后，当我点击另一个叠加的previous popus应该会消失，新人们应该出现在单击位置（即投影点）。当我点击其他任何地方screen.Im使用中的onTap事件记录的onclick弹出不应该出现。 （map_overlay）是我想说明，当有人点击地图上的投影点的布局。在code是下方map_overlay.xml可能是任意文件。

类：ItemizedOverlay

 公共布尔中的onTap（GeoPoint对象磷，图形页面图形页面）{

LayoutInflater充气=（LayoutInflater）cContext.getSystemService（Context.LAYOUT_INFLATER_SERVICE）;

的LayoutParams LP =新MapView.LayoutParams（ViewGroup.LayoutParams.FILL_PARENT，ViewGroup.LayoutParams.FILL_PARENT，P，LayoutParams.WRAP_CONTENT）;
的LinearLayout视图=（的LinearLayout）inflater.inflate（R.layout.map_overlay，NULL）;

mapView.removeView（视图）;
mapView.invalidate（）;
mapView.addView（查看，LP）;

mapView.invalidate（）;

返回true;
}
 

下面是主类中，即时通讯显示的投影点，这是工作的罚款，并即时致电我已经实现了活动的onTap另一个类如上图所示：

 公共**类的MapView **扩展MapActivity {
    私人的ArrayList＆LT; MyClass的＆GT; overlayItem;

    @覆盖
    公共无效的onCreate（包savedInstanceState）{
        super.onCreate（savedInstanceState）;
        的setContentView（R.layout.large_mapview）;
        图形页面=（图形页面）findViewById（R.id.mapview）;
       // mapView.setBuiltInZoomControls（真正的）;

        名单＆LT;覆盖＆GT; mapOverlays =调用MapView.getOverlays（）;
        可绘制绘制= this.getResources（）getDrawable（R.drawable.mappointer2）。
        ItemizedOverlay itemizedoverlay =新ItemizedOverlay（绘制，这一点）;
        OverlayItem overlayitem;
        的GeoPoint点;
        双纬度;
        双LNG;

        的for（int i = 0; I＆LT; overlayItem.size（）;我++）{

            纬度= Double.parseDouble（overlayItem.get（ⅰ）.getLatitude（））;
            液化天然气= Double.parseDouble（overlayItem.get（ⅰ）.getLongitude（））;
            点=新的GeoPoint（（INT）（LAT * 1E6），（INT）（LNG * 1E6））;

            overlayitem =新OverlayItem（点，1 +的toString（），overlayItem.get（我）.getDetails（）的toString（））;
            itemizedoverlay.addOverlay（overlayitem）;
            mapOverlays.add（itemizedoverlay）;

        }

        mapView.invalidate（）;
    }
}
 

解决方案

查看 Android的mapviewballoons 的GitHub上。有一个ItemizedOverlay，你可以扩展，这是否确切的事情。我在我的几个应用程序使用它。

Ive been trying to acheive the same, this is exactly what i want :-

i have implemented googleMapView with overlays, i have one issue i want to show a popup when clicked on each overlay, and when i click on another overlay the previous popus should disappear and new one should appear at the clicked location(ie projection points). And popup shouldnt appear when i click anywhere else on screen.Im using onTap event to record onclick. (map_overlay) is the layout that i want to show when someone click a projection point on the map. The code is below and map_overlay.xml could be any file.

Class: ItemizedOverlay

public boolean onTap(GeoPoint p, MapView mapView) {

LayoutInflater inflater = (LayoutInflater)cContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

LayoutParams lp = new MapView.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT, p, LayoutParams.WRAP_CONTENT);
LinearLayout view = (LinearLayout)inflater.inflate(R.layout.map_overlay, null);

mapView.removeView(view);    
mapView.invalidate();    
mapView.addView(view,lp);

mapView.invalidate();

return true;
}

Below is the Main class in which im displaying projection points which is working fine and im calling I have implemented the onTap event in another class as shown above:

public **class MapView** extends MapActivity{
    private ArrayList<MyClass> overlayItem ;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.large_mapview);
        mapView = (MapView) findViewById(R.id.mapview);
       // mapView.setBuiltInZoomControls(true);

        List<Overlay> mapOverlays = mapView.getOverlays();
        Drawable drawable = this.getResources().getDrawable(R.drawable.mappointer2);
        ItemizedOverlay itemizedoverlay = new ItemizedOverlay(drawable,this);
        OverlayItem overlayitem;
        GeoPoint point;
        double lat;
        double lng;        

        for (int i = 0; i < overlayItem.size(); i++) {

            lat = Double.parseDouble(overlayItem.get(i).getLatitude());
            lng = Double.parseDouble(overlayItem.get(i).getLongitude());
            point = new GeoPoint((int) (lat * 1E6),(int) (lng * 1E6));

            overlayitem = new OverlayItem(point, i+"".toString(), overlayItem.get(i).getDetails().toString());
            itemizedoverlay.addOverlay(overlayitem);
            mapOverlays.add(itemizedoverlay);

        }

        mapView.invalidate();
    }
}

Check out Android-mapviewballoons on github. Has an ItemizedOverlay that you can extend that does this exact thing. I use it in several of my apps.
