Answer 1

In InfoWindowAdapter change to

@Override
    public View getInfoWindow(Marker marker) {
        View view = ((Activity)context).getLayoutInflater()
                .inflate(R.layout.map_custom_infowindow, null);
        return view;
    }

    @Override
    public View getInfoContents(Marker marker) {

        return null;
    }

Use getInfoWindow instead of getInfoContents to provide full info window. Make sure to set appropriate backgrounds for root view, e.g. something with a triangle at the bottom center.
