  <p>I have a map view that covers the whole screen. On the top of it, there is a view pager. 
  The view pager consist of two parts, top 40% and bottom 60%, the top one is just a transparent view.</p>
  
  <p>While swiping the view pager, marker displayed on map should be located to middle of transparent top view 40%.</p>

  <p>How to achieve this?
  I tried this, but with no luck: </p>
  
  <pre><code>public void FollowVehicle(clsFollowMode vehicle){
       final LatLng vehiclePosition = new LatLng(vehicle.getLatitude(), vehicle.getLongtitude());
       Marker vehicleMarker = myGMap.addMarker(new MarkerOptions()
                                  .position(vehiclePosition)
                                  .title(vehicle.getDeviceName())
                                  .snippet(String.valueOf(vehicle.getSpeed()))
                                  .icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_vehicle_follow)));
  
       float zoom_lvl = myGMap.getCameraPosition().zoom;
  
       double dpPerdegree = 256.0*Math.pow(2, zoom_lvl)/170.0; 
       double screen_height = (double) mapContainer.getHeight(); 
       double screen_height_30p = -20.0*screen_height/100.0; 
       double degree_30p = screen_height_30p/dpPerdegree;
  
       LatLng centerlatlng = new LatLng( vehiclePosition.latitude + degree_30p, vehiclePosition.longitude );
  
       myGMap.animateCamera( CameraUpdateFactory.newLatLngZoom( centerlatlng, 15 ), 1000, null);
  }
