我有一个具有计算器名称数组集合的应用程序。选择后，我想为该项目推送计算器的实际视图。

这是我的代码，有人可以帮我编写一个允许我这样做的函数吗？

creationComplete="creationCompleted(event)"

        private function creationCompleted(event:FlexEvent):void
        {
            _collection = Album.collection;
            _collection.filterFunction = filterCollection;

            _evaluator.synonyms["four"] = new ArrayCollection(["4"]);

            grid.dataProvider = _collection;

这是我用来解决此问题的代码。在 flex 应用程序中有一个可以使用的 navigator.pushView 组件。我遇到的问题是我没有为每个计算器分配视图 ID。这必须在 ArrayCollection 容器中完成。

navigator.pushview( ViewID )
