title: setRecycledViewPool method in RecyclerView
body: <p>I am trying to understand what the setRecycledViewPool method actually does along with the RecyclerView in the following line of code where <code>mrecyclerView</code> is a RecyclerView object:</p>
  
  <pre><code>mrecyclerView.setRecycledViewPool(new RecyclerView.RecycledViewPool());
  </code></pre>
  
  <p>I read the Android documentation <a href="https://developer.android.com/reference/android/support/v7/widget/RecyclerView.RecycledViewPool.html" rel="noreferrer">link</a> and I still don't understand what it does clearly. Can someone explain to me its use and when to use it?</p>
