title: RecyclerView crashes when "scrapped or attached views may not be recycled"
body: <p>I'm using a simple implementation of <code>RecyclerView</code> taken from the Android website using a <code>StaggeredGridLayoutManager</code> and I keep getting this error that crashes my app:  </p>
  
  <pre><code>java.lang.IllegalArgumentException: Scrapped or attached views may not be recycled. isScrap:false isAttached:true

  <p>By simple, I literally mean it's the same implementation taken from <a href="https://developer.android.com/training/material/lists-cards.html#RecyclerView" rel="noreferrer">this page on their website</a>, the only difference being is that my grid item's layout is an <code>ImageView</code> and a couple of <code>TextView</code>s, so I won't bother reposting my code.  </p>
  
  <p>Anyone else getting this error and know how to deal with it?</p>
