Android – TabActivity or TabHost容器裡的Activity如何自訂標題列（TitleBar）

    因為TabActivity 裡本身有個TitleBar，如果Tab裡的Activity還想自訂TitleBar的話、會衝突，因為不能同時顯示兩個TitleBar、、

    這裡我們要在Tab裡的Activity持有TabActivity的引用，這樣就能在顯示某Activity時動態地自訂標題列。。

    需要注意的是標題列在TabActivity 裡，所以要想找到標題列的Button等等對象就到通過持有的引用來找了、、、

    特別要注意的就是找標題列對象，得在onResume裡自訂標題列之後，也就是把titlebar layout載入TabActivity之後再找，鬱悶了我好久、、、哦哦

    遇到的問題：當在不同的activity切換時，或者某activity因為使用者輸入文字，失去焦點，輸入完成後，標題列的按鈕再怎麼點擊都沒反應了。

    解決中。。。
