Question

我正在尝试为自定义MXDataGridItemRenderer设置alternatingItemColors，似乎没有任何效果。我已经尝试了设置我能想到的属性的每个组合，从应用程序到dataGrid，再到渲染器，autoDrawBackground的每个组合都设置为true或false而没有运气。最后，我希望使用自定义itemRenderer，它在标签后面有一组半透明基元，使用alternatingItemColors使行更容易阅读，但保持自定义渲染器的样式不变。任何建议将不胜感激。

谢谢，〜尼

好吧，我不习惯格式化，发布回复等等，但我只是想附加原帖，希望对每个人都有效......

再次，ItemRenderer：

这可能有点晚了，因为这是一个三个月的帖子，但是如果你还在寻找答案......看起来这可能是问题所在：

alternatingItemColors="#FFFFFF, #000000"

应该是：

alternatingItemColors="[#FFFFFF, #000000]"

如何让alternItemColors在spark MX DataGrid ItemRenderer中正常工作？
