title: RecycleView Unknown class
body: <p>I'm trying to create a sort of "ListView" for a mobile app using Kivy/Python.
  Regarding to the main documentation of a <a href="https://kivy.org/docs/api-kivy.uix.listview.html#module-kivy.uix.listview" rel="nofollow noreferrer">ListView</a>, seems to be "deprecated".</p>
  
  <blockquote>
    <p>ListView has been deprecated, use RecycleView instead.</p>
  </blockquote>
  
  <p>Well, I gave a look to <a href="https://kivy.org/docs/api-kivy.uix.recycleview.html#module-kivy.uix.recycleview" rel="nofollow noreferrer">RecycleView</a>, but unfortunately I get an error while using it in the KV module.</p>
  
  <blockquote>
    <p>kivy.factory.FactoryException: Unknown class </p>
  </blockquote>
  
  <p>I don't actually get what's wrong with it, i mean, is there something i should know about? The error is pretty straightforward, so my question is: Does kivy provide this module by default? or do i have to download it for some reason?</p>
  
  <p>I've been asking in the #kivy channel on IRC for such a day, but nobody seem to know the answer, or at least they do not answer me.</p>
