title: Gridview and RecyclerView synchronized scrolling
body: <p>I am trying to build a layout with recyclerview and gridview side by side. I need to sync scroll of both views. Currently, I managed to sync recyclerView with gridView:</p>
  
  <pre><code>recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
              @Override
              public void onScrolled(@NonNull RecyclerView recyclerView, int dx, int dy) {
                  gridView.scrollBy(0, dy);
              }
          });
  </code></pre>
  
  <p>The problem: when gridView is scrolled - cell that are outside of screen do not appear, it's empty.</p>
  
  <p>Second problem: how to sync gridview scrolling with recyclerview?</p>
  
  <p>Thank you for your answers!</p>
