title: Change Alpha on a Color object
body: <p>Is there a way to add aplha to color that i can get from a color string.
  Because now i can draw my color without the alpha by using the following code</p>
  
  <pre><code>      CircleOptions options = new CircleOptions().center(new LatLng(car.getLatitude(), car.getLongitude()))
            .radius(car.getRadius())
            .strokeColor(Color.argb(50,232,245,248))
            .strokeWidth(2)
            .fillColor(Color.parseColor(car.getColorString()));
  </code></pre>
  
  <p>This works fine. But i want to make the color more transparent. Is there a good way to add alpha do this color because i can only get out a "ColorString"</p>
