title: Save position of selected item in RecyclerView after update [Xamarin.Android]
body: <p>I am making app where i'm using <code>recyclerView</code> to handle with images. I must update list of images often (3 sec) but after update - scroll is going to top.
  To update <code>recyclerView</code> i use this code:</p>
  
  <pre><code>adapter = new ImageAdapter(this, DrawableList);
  RunOnUiThread(() =&gt; recyclerView.SetAdapter(adapter));
  </code></pre>
  
  <p>Is there any way to save position of scroll in <code>RecyclerView</code> or updating in background?</p>
