Android差距超过PagerTitleStrip

Question

I'm having an issue with my layout where there is a gap between the PagerTitleStrip and the ActionBar. Here's my layout and how it looks, it seems to display fine in the preview window but not on my device.

    <?xml version="1.0" encoding="utf-8"?>
<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
           android:id="@+id/fuelActivityViewPager"
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           android:gravity="center"
           android:orientation="vertical">

    <android.support.v4.view.PagerTitleStrip
        style="@style/titleStrip"
        android:id="@+id/pagerTitleStrip"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="top"/>

</android.support.v4.view.ViewPager>

Gap..

Answer 1

I figured it out. In my activity I had the action bar set to navigation tabs mode and it is deprecated/not available with the pager title strip. Once I removed it the space went away.
