這裏是一個代碼？BaseActivity類代碼，請 – IceJOKER

@IceJOKER對不起，這裏是代碼。 – lvl4fi4

您應該添加福爾摩斯主題，你的應用程序

<application android:icon="@drawable/icon" android:label="@string/app_name" 
    android:debuggable="false" android:theme="@style/Theme.Sherlock">

感謝一個loooooooooooooooot – lvl4fi4

@新的用戶，不客氣）只是使用谷歌 - 這是真正有用的工具）） – IceJOKER

是我嘗試過，但沒有熱量與我的問題相關 – lvl4fi4
