1、java list-》flex arrayCollection
java:
//第一种:返回对象列表 public List<Conf> getConfList(){ List<Conf> list = new ArrayList<Conf>(); for(int i = 0; i < 5; i++){ Conf conf = new Conf(); conf.setConfId(i); conf.setConfMsg("mes" + i); conf.setConfName("name" + 1); list.add(conf); } return list; } //第二种:返回map列表 public List<Map<String, String>> getConfList2(){ List<Map<String, String>> list = new ArrayList<Map<String, String>>(); for(int i = 0; i < 5; i++){ Map<String, String> map = new HashMap<String, String>(); map.put("confId", "" + (i + 1)); map.put("confName", "name" + (i + 1)); list.add(map); } return list; }
as:
将java的list转成ArrayCollection
public function confListHandle(listEvent:ResultEvent):void{ var result:ArrayCollection = listEvent.result as ArrayCollection; // Alert.show(":" + result[0].confName); dictGrid.dataProvider = result; }
mxml:
<!--列表--> <mx:DataGrid id="dictGrid" x="169" y="119" width="100%" height="100%" variableRowHeight="true"> <mx:columns> <mx:DataGridColumn headerText="序号" dataField="confId" width="50" textAlign="center"/> <mx:DataGridColumn headerText="名称" dataField="confName" width="190" wordWrap="true"/> <mx:DataGridColumn headerText="操作" width="50"> <mx:itemRenderer> <mx:Component> <mx:HBox> <mx:Script> <![CDATA[ import mx.events.CloseEvent; import mx.collections.ArrayCollection; import mx.controls.Alert; Alert.okLabel = "确定"; Alert.cancelLabel = "取消"; private function delDriver( e:Event) : void{ Alert.show("确定删除吗?","删除资源驱动",Alert.OK|Alert.CANCEL,null, function(e:CloseEvent):void{ if(e.detail == Alert.OK) { //文件key // var fileKey : String=outerDocument.dictGrid.selectedItem.newName; //调用方法,删除数据库记录 // outerDocument.dictRemote.delDict(fileKey); } else if(e.detail == Alert.CANCEL) { Alert.CANCEL; } }); } ]]> </mx:Script> <mx:Spacer /> <mx:LinkButton label="删除" click="delDriver(event)"></mx:LinkButton> </mx:HBox> </mx:Component> </mx:itemRenderer> </mx:DataGridColumn> </mx:columns> </mx:DataGrid>
