Map marker position with animateCamera to screen location x, y

Dears,

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.

While swiping the view pager, marker displayed on map should be located to middle of transparent top view 40%.

This image describe the story:

Sketch

How to achieve this? I tried this, but with no luck: 

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);
}

Any help? the above solution found here.

If I understood you correctly, then your problem is the fact that you placed the map as full screen fragmnet, and on top of this you placed the ViewPager. as a result when you center on the marker the map does that but the marker is under the ViewPager.

You can trick the map into thinking that it has a smaller size then it really is, by using the GoogleMap.setPadding method, you can read more about it here:
