如何TextView在android中更改使用颜色选择器的文本颜色和背景颜色.添加具有更改文本颜色的功能的注释和从颜色选择器中选择颜色的背景.

• 我试着在offerDetails Activity的backpress上调用我的OffersActivity(我正在使用ActivityGroup和TabActivity).

• 我得到错误到ArrayIndexOutOFBound ...最后两个我试着这个完成,但它没有由我完成..指导我..解决这个问题.在这个当我运行第一个选项卡是OffersActivity打开列表,当我点击列表项打开其详细信息视图(OfferDetailsActivity)并按返回它给错误强制关闭..
