概述本文实例讲述了Android基于BaseExpandableListAdapter实现的二级列表仿通话记录功能。分享给大家供大家参考,具体如下:

本文实例讲述了AndroID基于Baseexpandablelistadapter实现的二级列表仿通话记录功能。分享给大家供大家参考,具体如下:

androID SDK中带有这样类似的例子,但是那个还是静态数据,没有实际应用价值,参考意义不大。

网上找了很多,还是那样的情况,几乎是同一篇文章,大家转来转去。况且,那篇例子也是静态的数据。

还是自己试试,自己写一个吧。程序读取手机系统的通话记录,按联系人分组,显示到列表。

开发工具:eclipse
运行环境:htc G9 androID2.3.3

不多说,先看效果:

展开后的效果:

继续展开的效果:

这里的也是采用继承Baseexpandablelistadapter来实现,具体请看代码。
