在infoWindow中显示Geocode server(地理编码服务)

定义locator标签

<esri:Locator
　　id="locator"              
　　url="http://geocode.arcgis.com/arcgis/rest/services/World/GeocodeServer"
　　locationToAddressComplete="onLocationToAddressComplete(event)"
　　fault="myService_faultHandler(event)"
　　concurrency="last"
/>

给点添加鼠标事件

//给点添加鼠标事件,用于显示其定位时间
grahpic.addEventListener(MouseEvent.ROLL_OVER,onMapClick);                    
grahpic.addEventListener(MouseEvent.ROLL_OUT,maouseOutHandler);

调用坐标转换地址的服务

private function onMapClick():void{
　　var myp:MapPoint = new MapPoint(114.242593,30.631004,new SpatialReference(4326));
　　var wm:MapPoint = WebMercatorUtil.geographicToWebMercator(myp) as MapPoint;
　　locator.locationToAddress(wm,100);
}

调用成功后的处理函数,与标签中的locationToAddressComplete属性配置的函数一致

private function onLocationToAddressComplete(event:LocatorEvent):void{ 
　　var candidate:AddressCandidate = event.addressCandidate;
　　if (candidate != null && candidate.address){
　　　　WebMercatorUtil.geographicToWebMercator(candidate.location)
　　　　var g:Graphic = new Graphic(candidate.location, sps, candidate.address);
　　　　EsriGraphicsLayer.clear();
　　　　EsriGraphicsLayer.add(g);
　　　　var text:TextArea = new TextArea();
　　　　text.htmlText = "<b>地址:</b>" + candidate.address.Address.toString();
　　　　//+ "," + candidate.address.State.toString()
　　　　EsriMap.infoWindow.content = text;
　　　　EsriMap.infoWindow.show(g.geometry as MapPoint);              
　　}            
}

 失败后的回调函数

//回调失败时调用的函数
protected function myService_faultHandler(event:FaultEvent):void{ 
　　Alert.show(event.fault.message); 
}
