title: How to center ImageView in a toolbar?
body: <p>Been trying to center a logo inside my toolbar. When i navigate to the next activity, the "up affordance" icon is present, and it will push my logo slightly to the right. How can I keep my logo at the center of the toolbar, without removing the up affordance icon? </p>
  
  <p>This is my toolbar tag</p>

      android:paddingBottom="3dp"/&gt;
