mx:XMLListCollection 包含多个XMLListmx:ArrayCollection 包含多个mx:Array这两个不是包含关系，mx:XMLListCollection和mx:ArrayCollection 是集合类，相对XMLList和Array是包装关系，有点像JAVA里的int和Integer的关系Array就是数组，与JAVA不一样的地方时，里面的元素类型不需要一致，每一个元素都可以是任意类型；XMLList看名字就知道了，是一个XML的list，由多个XML组成，与Array比较像，只是元素是XML 1 dataProvider="{cards}" [Bindable] public var cards:ArrayCollection = new ArrayCollection( [ {label:"Visa", data:1}, {label:"MasterCard", data:2}, {label:"American Express", data:3} ]);或者： cards.addItem({label:"Visa", data:1}); 2。 dataProvider="{mystates.state}" <mx:Model id="mystates"> <states> <state label="Alabama" data="AL"/> <state label="Alaska" data="AK"/> <state label="Arizona" data="AZ"/> <state label="Arkansas" data="AR"/> <state label="California" data="CA"/> <state label="Colorado" data="CO"/> <state label="Connecticut" data="CT"/> </states> </mx:Model> 3。dataProvider="{treeData}" <mx:XMLList id="treeData"> <node label="Mail Box"> <node label="Inbox"> <node label="Marketing"/> <node label="Product Management"/> <node label="Personal"/> </node> <node label="Outbox"> <node label="Professional"/> <node label="Personal"/> </node> <node label="Spam"/> <node label="Sent"/> </node> </mx:XMLList> 4。内嵌到list中 <mx:HorizontalList id="CameraSelection" height="250" columnCount="3" columnWidth="125"> //这里的数据提供者也可以用json ,这里是用的标签的形式 <mx:dataProvider> <mx:Array> //比List中的dataProvider多了一个mx:Array <mx:Object label="Nokia 6630" icon="{phone1}"/> <mx:Object label="Nokia 6680" icon="{phone2}"/> <mx:Object label="Nokia 7610" icon="{phone3}"/> <mx:Object label="Nokia 7610" icon="{phone4}"/> </mx:Array> </mx:dataProvider> </mx:HorizontalList> [Bindable] [Embed(source="../assets/nokia6630.png")] public var phone1:Class; 5。 <mx:List id="myList" variableRowHeight="true" height="180" width="250" backgroundColor="white" initialize="initCellEditor();"//渲染器在这里通过as代码指定的 > //这里的dataProvider完全可以写在上面的属性里面哈 <mx:dataProvider> <mx:Object label="Alaska" data="Juneau" webPage="http://www.state.ak.us/"/> <mx:Object label="Alabama" data="Montgomery" webPage="http://www.alabama.gov/" /> <mx:Object label="Arkansas" data="Little Rock" webPage="http://www.state.ar.us/"/> </mx:dataProvider> </mx:List> 6. <mx:DataGrid id="dataGrid" dataProvider="{arrColl}" .../> <mx:ArrayCollection id="arrColl"> <mx:source> <mx:Array> <mx:Object label="中国" score="1" /> <mx:Object label="美国" score="0" /> <mx:Object label="法国" score="0" /> <mx:Object label="德国" score="0" /> <mx:Object label="俄罗斯" score="0" /> <mx:Object label="日本" score="0" /> <mx:Object label="意大利" score="0" /> <mx:Object label="捷克" score="1" /> <mx:Object label="西班牙" score="0" /> <mx:Object label="澳大利亚" score="0" /> <mx:Object label="韩国" score="0" /> <mx:Object label="肯尼亚" score="0" /> </mx:Array> </mx:source> </mx:ArrayCollection>
