title: Remove the Padding for Action Bar Menu Item using AppCompat
body: <p>I am Using Overlay Action Bar By Using the Following Style to my Activity</p>
  
  <p>style.xml</p>
  
  <pre><code>    &lt;style name="CustomActionBarTheme" parent="@style/Theme.AppCompat" &gt;
      &lt;item name="windowActionBarOverlay"&gt;true&lt;/item&gt;
      &lt;item name="android:background"&gt;#00f3ead8&lt;/item&gt;
      &lt;item name="android:windowBackground"&gt;@drawable/logo1024&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>I have only one menu item that is to be displayed Always </p>
  
  <p>menu.xml</p>
  
  <pre><code>&lt;menu xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:yourapp="http://schemas.android.com/apk/res-auto"&gt;
  &lt;item
      android:id="@+id/menusettings"
      android:orderInCategory="100"
      android:icon="@drawable/settings"
      android:title="Menu"
      yourapp:showAsAction="always"
      /&gt;
    &lt;menu&gt;
  </code></pre>
  
  <p>The Icon i.e the settings.png is getting padded by 8dp 
  But I want 0 padding on the top and bottom so that it covers the Entire Actionbar</p>
  
  <p>Please Help me out in deep trouble very close to the deadline of the project
  Thanks in advance</p>
