title: speed control of recyclerView
body: <p>I have 3 recycler view, when one is scrolling the two others scroll in same time, I'm using a OnScrollListener for doing it</p>
  
  <pre><code>    @Override
      public void onScrolled(RecyclerView recyclerView, final int dx, final int dy) {
               super.onScrolled(recyclerView, dx, dy);
                    recyclerView2.removeOnScrollListener(this);
                    recyclerView3.removeOnScrollListener(this);
                    recyclerView2.scrollBy(dx , 0);
                    recyclerView3.scrollBy(dx , 0);
                    recyclerView2.addOnScrollListener(this);
                    recyclerView3.addOnScrollListener(this);
       }
  </code></pre>
  
  <p>This is working fine but I would like that the recyclerView2 and recyclerView3 decelerate when scrolling</p>
  
  <p>I try to use fling() </p>
  
  <pre><code>recyclerView1.setOnFlingListener(new RecyclerView.OnFlingListener() {
  
           @Override
           public boolean onFling(int velocityX, int velocityY) {
                recyclerView2.fling(40* (int) Math.signum((double)velocityX), velocityY);
                recyclerView3.fling(60* (int) Math.signum((double)velocityX), velocityY);
                return true;     
           }
  });
  </code></pre>
  
  <p>This decelerate the 3 recycler instead of decelerate only the recyclerView2 and recyclerView3 </p>
