title: How do I make RecyclerView update its layout?
body: <p>I have a <code>RecyclerView</code> with a bunch of custom views which may change height after a while, because they contain <code>ImageView</code>s which load their image asynchronously. The <code>RecyclerView</code> does not pick up on this layout change, although I call <code>forceLayout</code> on the <code>ImageView</code>, and the <code>RecyclerView</code> is initialized with <code>setHasFixedSize(false)</code>. All container-parents of the <code>ImageView</code> have set <code>android:layout_height="wrap_content"</code>.</p>
  
  <p>How can I make the <code>RecyclerView</code> update its layout? With good'ol <code>ListView</code> this was not a problem. </p>
