Cocos2d-x 发布时间：2022-05-02 发布网站：大佬教程 code.js-code.com

大佬教程收集整理的这篇文章主要介绍了Cocos2d-x 3.3Bate0 ExpandedListView，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

之前写的ExpandedListView版本由于版本升级这里提供Cocos2d-x 3.3Bate0 版本

代码下载：http://download.csdn.net/detail/qqmcy/8033343

下面介绍下如何使用。

先介绍下

DJDataObject存放数据模型的类

DayReportListAdapter 自定义的adapter或是iOS中的cell

ListViewTest 示例类。

下面上代码啦
