我有一種情況，當我使用ViewPager作爲片段時，NavigationDrawer不會彈出，當我單擊其中一個NavigationDrawer項目時，它就會啓動。我正在使用材質設計， NavigationDrawer和ViewPager都是碎片。我的代碼是爲B當我使用ViewPager作爲片段時導航抽屜不會打開

我相信ViewPager應該在主佈局中。我仍然使這項工作100％的努力，但這樣做的：

<android.support.v4.widget.DrawerLayout 
xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:id="@+id/drawer_layout" 
android:layout_width="match_parent" android:layout_height="match_parent" 
tools:context="thehighestprimenumber.com.losprincipios.ChapterActivity"> 


<android.support.v4.view.ViewPager 
    android:id="@+id/pager" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" > 

    <FrameLayout android:id="@+id/containerBox" android:layout_width="match_parent" 
     android:layout_height="match_parent" /> 
</android.support.v4.view.ViewPager> 

<ListView android:id="@+id/drawer" 
    ... 
    /> 

</android.support.v4.widget.DrawerLayout>

這樣的navigationDrawer打開。

我的問題是，當我點擊導航抽屜上的一個項目時，片段不會更新。

，如果你知道如何解決這個問題，你會成爲我的一天=）
