【问题描述】：
- 我尝试在 offerDetails 的后台调用我的 OffersActivity Activity。（我正在使用 ActivityGroup 和 TabActivity）。
-
我收到 ArrayIndexOutOFBound 错误...最后两个我正在尝试 这要完成，但不是我做的..指导我..解决这个问题 问题。当我运行第一个选项卡时，OffersActivity 是打开的列表 当我单击列表项打开其详细信息视图 （OfferDetailsActivity）并按返回它给出错误强制关闭..
我应用了这个例子：- http://www.jtben.com/document/695851
但它给出了错误
