我正在使用Flex Mobile开发适用于iOS和Android的移动应用程序。在其中一个视图中,我正在使用Google地图和一个火花List控件显示StageWebView以显示另一个数据。我正在使用StageWebView以受益于Google Maps JavaScript API v3。示例代码如下:
<?xml version="1.0" encoding="utf-8"?>
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark" title="Clubs" backgroundAlpha="0"
viewActivate="view1_viewActivateHandler(event)"
backKeyPressed="view1_backKeyPressedHandler(event)"
initialize="view1_initializeHandler(event)">
<fx:Script>

import flash.sensors.Geolocation;

import spark.events.ViewNavigatorEvent;
private var myWebView:StageWebView;
[Bindable]
private var locations:ArrayCollection;
private var geolocation:Geolocation;
protected function view1_initializeHandler(event:FlexEvent):void
{
myWebView = new StageWebView();
myWebView.stage = this.stage;
}
protected function view1_viewActivateHandler(event:ViewNavigatorEvent):void
{
if(Geolocation.isSupported)
{
geolocation = new Geolocation();
geolocation.addEventListener(GeolocationEvent.UPDATE, onGeolocationChange);
}
}
override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void{
super.updateDisplayList(unscaledWidth, unscaledHeight);
if (myWebView) {
var point:Point = (new Point());
point = localToGlobal(point);
myWebView.viewPort = new Rectangle(point.x,point.y, stage.width,stage.height/3);
}
}
protected function view1_backKeyPressedHandler(event:Event):void
{
if (myWebView)
{
myWebView.viewPort = null;
myWebView = null;
}
navigator.popView();
}
protected function onGeolocationChange(event:GeolocationEvent):void
{
geolocation.removeEventListener(GeolocationEvent.UPDATE, onGeolocationChange);
locations = new ArrayCollection();
var location0:Object = new Object();
location0.lat = event.latitude;
location0.long = event.longitude;
locations.addItem(location0);
var location1:Object = new Object();
location1.lat = "42.697325";
location1.long = "23.315364";
locations.addItem(location1);
var location2:Object = new Object();
location2.lat = "42.696441";
location2.long = "23.321028";
locations.addItem(location2);
var url:String = "http://whozzzin.dev.mediatecture.at/gmapsformobile/map.php";
var counter:Number = 1;
for each(var location:Object in locations)
{
if(counter == 1)
{
url += "?locations["+counter.toString()+"][lat] = " + location.lat;
url += "&locations["+counter.toString()+"][long] = " + location.long;
}
else
{
url += "&locations["+counter.toString()+"][lat] = " + location.lat;
url += "&locations["+counter.toString()+"][long] = " + location.long;
}
counter++;
}
myWebView.loadURL(url);
}

<s:navigationContent>
<s:Button includeInLayout="{Capabilities.version.indexOf('IOS') > -1}" visible="{Capabilities.version.indexOf('IOS') > -1}" id="backButton" label="BACK" click="view1_backKeyPressedHandler(event)"/>
</s:navigationContent>
<s:List width="100%" contentBackgroundAlpha="0" id="placesList" dataProvider="{locations}" labelField="lat">

目前,该列表不可见,因为它出现在StageWebView后面。我的问题是如何在WebStageView之后准确定位List控件。
答案 0 :(得分:0)
您可以使用top
约束:
<s:List width="100%" top="{stage.height/3}" id="placesList"
修改:在trace(stage.height);
功能中添加updateDisplayList
,并查看stage.stageHeight
。这些值应该可以帮助您确定在这种情况下使用的确切top
值。

我是如何解决的:
我得到了WebStageView的底部并将一个新点从全局转换为本地x = 0和y = myWebView.bootom:
override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void{
super.updateDisplayList(unscaledWidth, unscaledHeight);
if (myWebView) {
var point:Point = (new Point(0,this.radiusDropDown.height));
point = localToGlobal(point);
myWebView.viewPort = new Rectangle(point.x,point.y, stage.width,stage.height/3);
this.placesList.y = globalToLocal(new Point(0,myWebView.viewPort.bottom)).y;
}
}
