title: Android recyclerview remove all item decorators
body: <p>I did this:</p>
  
  <pre><code>dividerItemDecoration = new DividerItemDecoration(
          recyclerView.getContext(),
          DividerItemDecoration.VERTICAL
      );
  recyclerView.addItemDecoration(dividerItemDecoration);
  </code></pre>
  
  <p>Then i change devices orientation, so now i dont have that dividerItemDecoration, and i want to delete divider from recyclerView. Is it possible?</p>
