title: How to vertically center menu item on toolbar less than 48dp?
body: <p>I'm trying to vertical center a simple menu item on my 30dp height toolbar.  I realize that Material Guidelines suggests a toolbar of 48dp, but I have too many items in my screen to give up any real estate.  There must be a way of vertically centering the menu item in my toolbar??</p>
  
  <p>Menu Inflation:</p>
  
  <pre><code>@Override
  public boolean onCreateOptionsMenu(Menu menu) {
      super.onCreateOptionsMenu(menu);
      getMenuInflater().inflate(R.menu.menu_main, menu);
      return true;
  }
  </code></pre>
  
  <p>Menu_main.xml:</p>
  
  <pre><code>&lt;menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"&gt;
      &lt;item
          android:title="Function"
          android:id="@+id/menu_func_keys"
          app:showAsAction="always" /&gt;
  &lt;/menu&gt;
  </code></pre>
  
  <p>Here's what I'm seeing:
