title: Nested Scroll View height Issue
body: <p>I have implemented Google Maps with bottomsheet. However when I check the layout, the map is on the top of the screen, not occupying the whole width and height of the screen. I've tried many ways to fix this, but no luck.</p>

  <p>Below is the layout code:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  
  &lt;LinearLayout android:layout_height="match_parent"
  android:layout_width="match_parent"

      &lt;android.support.v4.widget.NestedScrollView
          android:layout_width="match_parent"

          &lt;RelativeLayout

              android:layout_height="match_parent"
              android:layout_gravity="fill_vertical"
             &gt;
              &lt;fragment  xmlns:android="http://schemas.android.com/apk/res/android"

                  xmlns:tools="http://schemas.android.com/tools"
                  android:id="@+id/map"

                  /&gt;
          &lt;/RelativeLayout&gt;
      &lt;/android.support.v4.widget.NestedScrollView&gt;
  
  
      &lt;include layout="@layout/test"
          android:id="@+id/design_bottom_sheet"/&gt;
  
  
  
  &lt;/android.support.design.widget.CoordinatorLayout&gt;
  
  
  
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>Could you please have a look at this and let me know where exactly is the issue?
  Thanks. </p>
