这对我来说很奇怪,但我也是Spark的新手。我有一个带有itemrenderer的List类。如何让itemrenderer在它们之间划分List宽度?通常情况下,我认为这将是一个简单的方法,因为给渲染器一个宽度的百分比,但没有任何工作。有什么想法吗?
应用:
<?xml version="1.0" encoding="utf-8"?>
<s:Application
minHeight="600"
minWidth="955"
xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx">
<fx:Declarations>
<s:ArrayCollection id="dta">
<fx:Object
label="one" />
<fx:Object
label="two" />
<fx:Object
label="three" />
<fx:Object
label="four" />
</s:ArrayCollection>
</fx:Declarations>
<s:List
width="100%"
borderColor="red"
dataProvider="{dta}"
xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
itemRenderer="ProgressIndicatorItemRenderer">
<s:layout>
<s:HorizontalLayout gap="0" />
</s:layout>
</s:List>
</s:Application>
的itemRenderer:
<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer
width="100%"
xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
autoDrawBackground="false"
showsCaret="false">
<s:states>
<s:State name="normal" />
<s:State name="selected" />
<s:State name="done" />
</s:states>
<s:Rect id="progressIndicatorBackground"
left="0" right="0" top="0" bottom="0">
<s:fill>
<s:SolidColor
color.done="0xCCCCCC"
color.normal="0xCCCCCC"
color.selected="0xF6A139"
alpha="1" />
</s:fill>
</s:Rect>
<s:Label
width="100%"
text="{data.label}" />
</s:ItemRenderer>
答案 0 :(得分:6)
我认为你只是缺少布局本身的一些属性:
<s:List width="100%" useVirtualLayout="false" borderColor="red" dataProvider="{ dta }"
itemRenderer="ProgressIndicatorItemRenderer">
<s:layout>
<s:HorizontalLayout gap="0" requestedColumnCount="-1" requestedMinColumnCount="-1" variableColumnWidth="true" />
</s:layout>
</s:List>
将variableColumnWidth设置为true并将useVirtualLayout设置为false可以解决您的问题。 RequestedColumnCount和requestedMinColumnCount默认设置为-1,但最好明确设置它们:)
我希望上面的代码有所帮助。
