title: How to position subtitle above title in Android Toolbar?
body: <p>I am using</p>
  
  <pre><code>&lt;android.support.v7.widget.Toolbar
      android:id="@+id/toolbar"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:background="@color/colorPrimary"
      android:minHeight="?android:attr/actionBarSize"
      app:contentInsetStartWithNavigation="0dp" /&gt;
  </code></pre>
  
  <p>with</p>
  
  <pre><code>Toolbar toolbar = findViewById(R.id.toolbar);
  toolbar.setTitle(myTitle);
  toolbar.setSubtitle(mySubtitle);
  </code></pre>
  
  <p>to set the title and subtitle in my Toolbar. They are displayed with the subtitle beneath the title.</p>
  
  <p>However, how can I make the subtitle appear <strong><em>above</em></strong> the title?</p>
  
  <p>To get the desired effect, I could make the title look like a subtitle (and vice versa), but is there a better, non-hacky solution?</p>
