我有一个大问题，我无法解决它。我有一个用Flash Develop编写的应用程序，用于在工作期间打入和关闭员工并跟踪他们的位置，并在他们进入/退出时跟踪他们的位置。当位置服务一直处于开启状态时，一切正常。但是，如果员工想要关闭位置服务（例如隐藏他的位置），当打开它时，应用程序就无法正常工作 - 它总是告诉我们位置我们静音（关闭）。退出申请并重新开始后，它恢复正常。
有什么建议吗？
我正在使用的代码：
我需要自定义事件来触发位置事件...
package MyEvents {
import flash.events.Event;
public class GeoLocUpdateEvent extends Event {
public static const GEOLOC_UPDATED:String = "GEOLOC_UPDATED";
public static const GEOLOC_NOTSUPPORTED:String = "GEOLOC_NOTSUPPORTED";
public static const GEOLOC_MUTED:String = "GEOLOC_MUTED";
public var latitude:Number;
public var longitude:Number;
public var precision:Number;
public function GeoLocUpdateEvent(type:String) { super(type); }
}
}
在被问到时实际捕获地理位置的类：
package Utils.Geoloc {
import flash.display.Sprite;
import flash.events.Event;
import flash.events.GeolocationEvent;
import flash.sensors.Geolocation;
import MyEvents.GeoLocUpdateEvent;
public class getGeoloc extends Sprite {
private var counter:int;
private var _geo:Geolocation;
public function getGeoloc() {
this.addEventListener(Event.REMOVED_FROM_STAGE, deleteListeners);
}
public function getloc():void {
counter=1;
_geo = new Geolocation();
if (Geolocation.isSupported) {
if (!_geo.muted) {
_geo.addEventListener(GeolocationEvent.UPDATE, geolocationUpdateHandler);
_geo.setRequestedUpdateInterval(1500);
} else {
var custEvent:GeoLocUpdateEvent = new GeoLocUpdateEvent(GeoLocUpdateEvent.GEOLOC_MUTED);
this.dispatchEvent(custEvent);
_geo = null;
}
} else {
custEvent = new GeoLocUpdateEvent(GeoLocUpdateEvent.GEOLOC_NOTSUPPORTED);
this.dispatchEvent(custEvent);
_geo = null;
}
}
private function geolocationUpdateHandler(ev:GeolocationEvent):void {
counter--;
if (counter<0) {
if (ev.horizontalAccuracy < 40) {
var custEvent:GeoLocUpdateEvent = new GeoLocUpdateEvent(GeoLocUpdateEvent.GEOLOC_UPDATED);
custEvent.latitude = ev.latitude;
custEvent.longitude = ev.longitude;
custEvent.precision = ev.horizontalAccuracy;
this.dispatchEvent(custEvent);
_geo.removeEventListener(GeolocationEvent.UPDATE, geolocationUpdateHandler);
_geo = null;
}
}
}
private function deleteListeners(ev:Event):void {
_geo = null;
}
}
}

关闭位置服务后，即使打开了locatgion服务，地理位置对象也会永久静音。我总是收到零作为答案，即使他们无法退房，因为“位置服务已关闭”......
