你的itemRenderer：

pre $ var $ index $ var $ index $

有关 listData.owner 和 listCollectionView.getItemIndex（）方法。

How to show the item index in my item renderer.Owner of the item renderer is TileList. http://www.swsd.k12.pa.us/baresvle/mathmaterials/numbers/number_grid.jpg

My best guess is try something like this in your itemRenderer:

var index: int = ((listData.owner as TileList).dataProvider as ListCollectionView).getItemIndex())

More info on listData.owner and the listCollectionView.getItemIndex() method.
