Question

我需要您帮助找到按创建日期时间排序数组的解决方案。我试试这个，但这个功能似乎只按日期排序，而不是按时间排在一起。

private function triImgDate(folder:Array):void {
        var acDirectory:ArrayCollection = new ArrayCollection();

        for each (var tmp:File in folder) {
            if (!tmp.isDirectory) {
                if (tmp.extension != null && ArrayFunction.inArray(tabExt, tmp.extension.toLowerCase()))
                {

                    listeImages.addItem(tmp);

                }
            }
            else {
                triImgDate(tmp.getDirectoryListing());
            }
        }

        var dataSortField:SortField = new SortField();
        dataSortField.name = "creationDate";
        dataSortField.numeric = false;
        var numericDataSort:Sort = new Sort();
        numericDataSort.fields = [dataSortField];
        listeImages.sort = numericDataSort;
        listeImages.refresh();



    }

所以，如果你能帮助我。

祝你好运

private function triImgDate(folder:Array):void {


        var acDirectory:ArrayCollection = new ArrayCollection();
        var arTempListeImages:ArrayCollection = new ArrayCollection();
        var arTempListeCompar:ArrayCollection = new ArrayCollection();


        var objImg:Object;
        for each (var tmp:File in folder) {
            if (!tmp.isDirectory) {
                if (tmp.extension != null && ArrayFunction.inArray(tabExt, tmp.extension.toLowerCase())) {

                    objImg= new Object();
                    //listeImages.addItem(tmp);
                    arTempListeImages.addItem(tmp);
                    objImg.creationDate=tmp.creationDate;
                    objImg.url=tmp.url;
                    objImg.pos=arTempListeCompar.length;
                    arTempListeCompar.addItem(objImg)


                }
            } else {
                triImgDate(tmp.getDirectoryListing());
            }
        }

        var dataSortField:SortField = new SortField();
        dataSortField.name = "creationDate";
        dataSortField.compareFunction = function (a:Object, b:Object) : int {
            var na:Number = a.creationDate.getTime();
            var nb:Number = b.creationDate.getTime();

            if (na < nb)
                return -1;

            if (na > nb)
                return 1;

            return 0;
        };

        var numericDataSort:Sort = new Sort();
        numericDataSort.fields = [dataSortField];

        arTempListeCompar.sort= numericDataSort;
        arTempListeCompar.refresh();
        var cpt:int=0;
        for each (var objTem:Object in arTempListeCompar) {

            listeImages.addItem(arTempListeImages[arTempListeCompar[cpt].pos]);
            cpt++;
        }

        arTempListeImages=[];
        arTempListeCompar=[];
        acDirectory=[];

    }

你在这里要做的是用字符串表示比较twe个日期，这显然不是一个好方法。

您应该使用android:required="false"对象的compareFunction属性。这样的事情（未经测试）：

SortField
