title: Remove shadow between actionbar and tabs
body: <p>I am trying to remove the shadow between my tabs and the actionbar, and I want to have shadow below the slidingTabs. I have implemented my tabs with <a href="https://github.com/codepath/android_guides/wiki/Sliding-Tabs-with-PagerSlidingTabStrip" rel="nofollow noreferrer">this</a> approach. Which means it is not possible to configure the actionbar layout with the normal theme approach.</p>
  
  <p>Here is a picture of what I want:

  <p>How can I do this?</p>
  
  <p>Edit:
  Here is the XML file:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;com.astuetz.PagerSlidingTabStrip
      android:id="@+id/tabs"
      app:pstsShouldExpand="true"
      app:pstsTextAllCaps="true"
      app:pstsIndicatorHeight="5dp"
      app:pstsIndicatorColor="#FFFFFF"        
      app:pstsDividerColor="#CE2A2F"        
      android:textColor="#FFFFFF"
      android:background="#CE2A2F"
      android:layout_width="match_parent"
      android:layout_height="48dp"&gt;
  &lt;/com.astuetz.PagerSlidingTabStrip&gt;
  
  &lt;android.support.v4.view.ViewPager
      android:id="@+id/viewpager"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:background="@android:color/white" /&gt;
  </code></pre>
