Question

我在Flex（Adobe AIR）中遇到奇怪的QNX问题，我创建了一个init（）;函数，在其中我添加了test_list（）函数，但QNX列表没有显示在UI上。请参阅下面的代码以获取摘要和以下链接以获取完整代码：

摘要

        private function init() : void {
            credentials = String(data);

            var arr:Array = new Array();
            arr.push("item 1");
            arr.push("item 2");

            indexArrayCollection = new ArrayCollection();

            subsonicIndexList = new DataProvider(arr);

            //subsonicIndexList = new DataProvider(indexArrayCollection.source);
            //get_indexList(null);

            test_list();
        }

        private function test_list() : void {
            var arrMonth:Array=[];
            // add objects with a label property
            arrMonth.push({label: "January"});
            arrMonth.push({label: "February"});
            arrMonth.push({label: "March"});
            arrMonth.push({label: "April"});
            arrMonth.push({label: "May"});
            arrMonth.push({label: "June"});
            arrMonth.push({label: "July"});
            arrMonth.push({label: "August"});
            arrMonth.push({label: "September"});
            arrMonth.push({label: "October"});
            arrMonth.push({label: "November"});
            arrMonth.push({label: "December"});

            var myList:List = new List();            
            myList.setPosition(100, 100);            
            myList.width = 300;            
            myList.height = 400;
            myList.columnWidth = 100;

            //set the dataProvider
            myList.selectionMode = ListSelectionMode.MULTIPLE;
            myList.scrollDirection = ScrollDirection.VERTICAL;
            myList.dataProvider = new DataProvider(arrMonth);

            myList.addEventListener(ListEvent.ITEM_CLICKED, showAlert);
            myList.addEventListener(ScrollEvent.SCROLL_END, showAlert);
            myList.addEventListener(ScrollEvent.SCROLL_BEGIN, showAlert);

            this.addChild(myList);
        }

您需要将任何QNX组件添加到包装器。如下所示： http://corlan.org/2011/03/28/creating-playbook-apps-with-flex-and-qnx-ui-components/

所以你需要这个动作脚本：

// this.addChild(myList);
dateWrapper.addChild(myList);

这是MXML

<mx:UIComponent id="dateWrapper"/>

Flex中的QNX列表根本没有出现！
