public class Geolocation
继承Geolocation Inheritance EventDispatcher Inheritance Object

语言版本: ActionScript 3.0
运行时版本: AIR 2, Flash Lite 4

为响应设备的位置传感器,Geolocation 类调度事件。

如果设备支持 geolocation,您可以使用此类获得设备当前的地理位置。地理位置以纬度和经度坐标形式(以 WGS-84 标准格式)显示在设备上。当设备的位置更改时,可以收到关于更改的更新。如果设备支持此功能,您将可以获得关于位置的最新更改的高度、精度、标题、速度和时间戳的信息。

AIR 配置文件支持:仅移动设备支持此功能。桌面或 AIR for TV 设备不支持此功能。您可以使用 Geolocation.isSupported 属性在运行时测试是否受支持。有关在多个配置文件之间支持 API 的详细信息,请参阅 AIR 配置文件支持

注意:要在 iOS 中启用 Geolocation,请确保对应用程序 xml 文件的 infoAdditions 元素添加一个键值对。有关 infoAdditions 元素的更多信息,请参阅 iOS 设置

属性详细信息

isSupported

属性
isSupported:Boolean  [只读]

语言版本: ActionScript 3.0
运行时版本: AIR 2, Flash Lite 4

位置传感器在设备上是否可用,可用为 true,不可用为 false



实现
    public static function get isSupported():Boolean
    

locationAlwaysUsePermission

属性 
locationAlwaysUsePermission:Boolean

语言版本: ActionScript 3.0
运行时版本: AIR 29

此属性确定 geolocation 的访问权限类型使用情况。权限类型可以为“始终使用”或“在使用中”。如果此属性设置为 false,它将请求“在使用中”权限或“始终使用”权限。在调用 requestPermission() 之前设置此属性。 此属性的默认值为 false



实现
    public function get locationAlwaysUsePermission():Boolean
    public function set locationAlwaysUsePermission(value:Boolean):void
    

muted

属性 
muted:Boolean  [只读]

语言版本: ActionScript 3.0
运行时版本: AIR 2

指定用户是已经拒绝对 geolocation 的访问 (true) 还是已经允许对 geolocation 的访问 (false)。当此值发生变化时,会调度 status 事件。



实现
    public function get muted():Boolean

相关 API 元素

permissionStatus

属性 
permissionStatus:String  [只读]



实现
    public static function get permissionStatus():String
构造函数详细信息

Geolocation

()构造函数
public function Geolocation()

语言版本: ActionScript 3.0
运行时版本: AIR 2, Flash Lite 4

创建新的 Geolocation 实例。

方法详细信息

requestPermission

()方法
public function requestPermission():void

setRequestedUpdateInterval

()方法 
public function setRequestedUpdateInterval(interval:Number):void

语言版本: ActionScript 3.0
运行时版本: AIR 2, Flash Lite 4

用于设置更新的时间间隔(以毫秒为单位)。更新间隔仅用作节省电池电量的提示。位置更新间的实际时间可能大于或小于此值。使用此方法对更新间隔所做的任何更改都将影响所有注册的 update 事件侦听器。无需调用 setRequestedUpdateInterval 方法即可使用 Geolocation 类。在这种情况下,平台将根据其默认间隔返回更新。

注意:第一代 iPhone 没有配备 GPS 装置,仅偶尔调度 update 事件。在这些设备上,Geolocation 对象最初会调度一个或两个 update 事件。信息变更显著时,它就会调度 update 事件。

参数

interval:Number — 请求的更新间隔。如果 interval <= 0,则对此方法的任何调用都无效。


引发
ArgumentError — 指定的 interval 小于零。
事件详细信息

permissionStatus

事件
事件对象类型: flash.events.PermissionEvent

status

事件  
事件对象类型: flash.events.StatusEvent
属性 StatusEvent.type = flash.events.StatusEvent.STATUS

语言版本: ActionScript 3.0
运行时版本: AIR 2, Flash Lite 4

Geolocation 对象在用户更改对位置传感器的访问时调度 status 事件。例如,如果为了响应设备提示,用户阻止应用程序访问位置数据,则 Geolcation 对象将调度 status 事件。当位置传感器不可用的地区的状态发生更改时,Geolocation 实例的 muted 属性为 true

定义 status 事件对象的 type 属性值。

此事件具有以下属性:

属性
bubblesfalse
cancelablefalse;没有要取消的默认行为。
code对象状态的描述。
currentTarget当前正在使用某个事件侦听器处理 Event 对象的对象。
level消息类别,例如 "status""warning""error"
target报告其状态的对象。

相关 API 元素

update

事件  
事件对象类型: flash.events.GeolocationEvent
属性 GeolocationEvent.type = flash.events.GeolocationEvent.UPDATE

语言版本: ActionScript 3.0
运行时版本: AIR 2, Flash Lite 4

为响应来自位置传感器的更新,调度 update 事件。在下列情况下调度该事件:

  • 当通过 addEventListener() 附加新的侦听器函数时,此事件将一次性传送给所有注册的侦听器,以提供位置的当前值。注意:如果设备具有最后已知的位置,AIR 将立即调度第一个事件;您的代码必须知道初始调度的事件可能不包含当前位置。
  • 以设备确定的间隔从平台获得位置更新时。
  • 当应用程序丢失对位置的更改时(例如,在休眠后唤醒应用程序)。

注意:第一代 iPhone 没有配备 GPS 装置,仅偶尔调度 update 事件。在这些设备上,Geolocation 对象最初会调度一个或两个 update 事件。信息变更显著时,它就会调度 update 事件。

定义 GeolocationEvent 事件对象的 type 属性的值。

此事件具有以下属性:

属性
bubblesfalse
cancelablefalse;没有要取消的默认行为。
currentTarget当前正在使用某个事件侦听器处理 Event 对象的对象。
target接收数据的 Geolocation 对象。

在下面的示例中,应用程序会在收到 geolocation update 事件时,显示这些事件的维度、经度和水平精度。

[ X ]为什么显示为英语?
《ActionScript 3.0 参考》中的内容以英语显示

《ActionScript 3.0 参考》中的部分内容未翻译成所有语言。当某个语言元素未翻译时,将显示为英语。例如,ga.controls.HelpBox 类未翻译成任何语言。因此在简体中文版的参考中,ga.controls.HelpBox 类显示为英语。
