title: YouTube player full screen issue
body: <p>I was trying to implement YouTubePlayerView in View Pager whose parent view have a fixed height. When i click full screen/exit mode in YouTube player it's adjusting only with respect to view pager's parent height, which i guess is an obvious behavior. </p>
  
  <pre><code>        &lt;RelativeLayout
              android:visibility="visible"
              android:layout_width="match_parent"
              android:layout_height="250dp"&gt;
              &lt;android.support.v4.view.ViewPager
                  android:id="@+id/productImageSlider"
                  android:layout_width="match_parent"
                  android:layout_height="match_parent"
                  android:layout_alignParentTop="true" /&gt;
              &lt;me.relex.circleindicator.CircleIndicator
                  android:id="@+id/indicator"
                  android:layout_width="match_parent"
                  android:layout_height="48dp"
                  android:layout_alignParentBottom="true"/&gt;
          &lt;/RelativeLayout&gt;
  </code></pre>
  
  <p>Now, as new in android, i want to know, if re-parenting the ViewPager on entering full screen mode is a good option to make it work or do i have other choices? </p>
