更改導航抽屜與片段DROM android.app.fragment到android.support.v4.app.fragment

Question

嗨我有一個問題，因爲我已經在我的應用程序實現的抽屜式導航欄，但我也希望有谷歌地圖在我應用程序和問題是他們使用不同的片段庫。

抽屜使用android.app.fragment而地圖需要android.support.v4.app.fragment有沒有什麼辦法可以改變我的導航抽屜也android.support.v4.app.fragment因爲谷歌地圖犯規上的版本沒有support.v4

所以，現在運行我的問題：有沒有辦法來改變導航抽屜一個support.v4版本我的代碼如下。 謝謝！

從ActionBarActivity不Activity擴展您的類，那麼你將能夠使用從支持的lib片段在你的應用程序
