title: RecyclerView scrollToPosition not trigger scrollListener
body: <p>I'm using RecyclerView, with ScrollListener:</p>
  
  <pre><code>mRecyclerView.setOnScrollListener(new RecyclerView.OnScrollListener()
  {
          @Override
          public void onScrollStateChanged(RecyclerView recyclerView, int newState)
          {
              super.onScrollStateChanged(recyclerView, newState);
          }
  
          @Override
          public void onScrolled(RecyclerView recyclerView, int dx, int dy)
          {
              super.onScrolled(recyclerView, dx, dy);
              // Do my logic
          }
   });
  </code></pre>
  
  <p>When I scroll with the finger, the scroll listener triggered fine.</p>
  
  <p>But when I scroll progrematically, like that:</p>
  
  <pre><code>mRecyclerView.scrollToPosition(LAST_POSITION);
  </code></pre>
  
  <p>The scroll listener is not triggered.</p>
