Android - TabActivity or TabHost容器里的Activity如何自定义标题栏（TitleBar）

    因为TabActivity 里本身有个TitleBar，如果Tab里的Activity还想自定义TitleBar的话、会冲突，因为不能同时显示两个TitleBar、、

    这里我们要在Tab里的Activity持有TabActivity的引用，这样就能在显示某Activity时动态地自定义标题栏。。

    需要注意的是标题栏在TabActivity 里，所以要想找到标题栏的Button等等对象就到通过持有的引用来找了、、、

    特别要注意的就是找标题栏对象，得在onResume里自定义标题栏之后，也就是把titlebar layout载入TabActivity之后再找，郁闷了我好久、、、哦哦

    遇到的问题：当在不同的activity切换时，或者某activity因为用户输入文字，失去焦点，输入完成后，标题栏的按钮再怎么点击都没反应了。

    解决中。。。
