title: How can I change a View's visibility based on whether a list is empty or not
body: <p>I have a <code>List</code> in a model that bounds to a layout using the data-binding lib. How can I change a <code>View</code>'s visibility based on the list's <code>isEmpty()</code> condition? Something like <code>android:visibility="@{model.list.isEmpty() ? View.INVISIBLE : View.VISIBLE}"</code>  </p>
