title: Changing the height of a Xamarin Forms NavigationPage Toolbar
body: <p>I am trying to change the height of a Xamarin Forms Toolbar that is being rendered on Android with AppCompat. There is no height property from Forms to set this so I've attempted setting the <code>layout_height</code> in the <code>toolbar.axml</code> as follows </p>
  
  <pre><code>&lt;android.support.v7.widget.Toolbar 
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      android:id="@+id/toolbar"
      android:layout_width="match_parent"
      android:layout_height="128dp"
      android:minHeight="?attr/actionBarSize"
      android:background="?attr/colorPrimary"
      android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
      app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
      app:layout_scrollFlags="scroll|enterAlways" /&gt;
  </code></pre>
  
  <p>This doesn't change the height.</p>
  
  <p>I've also tried setting </p>
  
  <ul>
  <li>android:minHeight </li>
  <li>android:height</li>
  <li>height</li>
  <li>android:actionBarSize</li>
  </ul>
  
  <p>but those do not change the height either.</p>
  
  <p>FWIW, when using Xamarin Forms non-AppCompat NavigationPage with the ActionBar, I was able to set the height with <code>android:height</code>. </p>
