Android如何在SherlockFragment中轉換sherlockActivity

Question

在使用與SherlockActivity不同的SherlockFragmentActivity之前，我在其中包括了用於所有治療的DrawerMenu並可以正確行走。 但是我決定更改SherlockActivity中的SherlockFragment ，以便從所有視圖上的DrawerMenu受益。 我嘗試了Fragment第一個Activity ，但它沒有出現，但是包含數據庫中數據的列表沒有出現。 請幫幫我。

Answer 1

在我的代碼中一切都正確。 顏色除外。 實際上， @drawable/background1巫婆是我列表的背景顏色與@color/font_color巫婆是我的列表項的顏色相同。
