Question

I have the basic xml setup…

    <LinearLayout
     xmlns:android="http://schemas.android.com/apk/res/android"
     android:orientation="vertical"
     android:layout_width="fill_parent"
     android:layout_height="fill_parent">

    <android.support.v4.view.ViewPager
     android:id="@+id/viewpager"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:layout_gravity="center" >

    <android.support.v4.view.PagerTitleStrip
     android:id="@+id/pagertitlestrip"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:layout_gravity="top" />
    </android.support.v4.view.ViewPager>

    </LinearLayout>

I am overriding getPageTitle in the adapter.
I get an inflate pagertitlestrip error.
Am I missing something here?

If I remove the pagertitlestrip xml the pageviewer works fine with multiple fragments.

Answer 1

sounds like you are including an old version of the compat library. Try with v9.
