title: Android RecyclerView wrong childCount
body: <p>I created a simple RecyclerView with an adapter and sometimes I need to get the count of child views in my RecyclerView outside the adapter.</p>
  <p>I use: <code>((LinearLayoutManager) myRecyclerView.getLayoutManager()).getChildCount()</code> for this. But I never get the real count of views inside the RecyclerView.</p>
  <p>For example, I add 10 items to my list and call <code>adapter.notifyDataSetChanged()</code>. After this I call <code>((LinearLayoutManager) myRecyclerView.getLayoutManager()).getChildCount()</code> I get 4.</p>
  <p>Can someone explain me how to get the real count of views inside the RecyclerView?</p>
