title: Android Recyclerview Issue
body: <p>I am trying to get look and feel of some working app UI. Now i got stuck on one of its activity flow. Like <a href="https://www.dropbox.com/s/velzyhgi4iz5614/20170108_221050.mp4?dl=0" rel="nofollow noreferrer">this</a>.
  I am stuck on 2 things:</p>
  
  <p><strong>Issue is</strong> : How to get binding between marker and recyclerview like in video. I as well wanted to show marker according to item visible in recyclerview. </p>
  
  <p><strong>Done</strong>: I have tried recyclerview addonScrollListener but thats not working for me. </p>
  
  <p><strong>Recyclerview :</strong></p>
  
  <pre><code> final LinearLayoutManager manager = new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false);
          recyclerView.setLayoutManager(manager);
          recyclerView.setHasFixedSize(true);
          this.bottomSheetAdapter1 = new com.development.haebix.adapters.BottomSheetAdapter(this, mEventInfos);
  
          recyclerView.setAdapter(bottomSheetAdapter1);
          recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
              @Override
              public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
                  super.onScrollStateChanged(recyclerView, newState);
  
                  setMarkerSelected(mEventInfos.get(newState).getMarker());
              }
          });
  </code></pre>
  
  <p><strong>Change marker color according to position code</strong></p>
  
  <pre><code>private void setMarkerSelected(Marker marker) {
          if (previousMarker != null) {
              previousMarker.setIcon(BitmapDescriptorFactory.fromBitmap(new IconGenerator(this)
                      .makeIcon("school")));}
          IconGenerator icon = new IconGenerator(this);
          icon.setStyle(IconGenerator.STYLE_ORANGE);
          marker.setIcon(BitmapDescriptorFactory.fromBitmap(icon.makeIcon("school")));
          previousMarker = marker;
  
      }
  </code></pre>
