     CameraUpdate update = CameraUpdateFactory.newLatLngZoom(ll, 18); 

     MarkerOptions options = new MarkerOptions()

バッツPogiはこの希望にしてみてください@これはあなたを助けることができます。..

Marker marker = googleMap.addMarker(new MarkerOptions() 
       .position(new LatLng(location.getLatitude(),location.getLatitude())) 
      .icon(BitmapDescriptorFactory.fromResource(R.drawable.yourImage)));
