i believe viewpager should inside main layout. i'm still struggling making work 100%, doing:
<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> this way navigationdrawer opens.
my problem is, when click on item on navigation drawer, fragment doesn't update.
if know how solve this, you'd make day =)
