            rate = Transportation.getDriverRate(value.toString(),
                    CityListForm.selectedCity);
            rate = (Integer.parseInt(rate)) > 25 ? "" + 5 : ""

                image = (Image.createImage(rate));

            Style style = label.getStyle();
            style.setBgColor(16777215);

            label.setPreferredH(42);
            return label;
        }
    });

Answer 1

Use List.setMutableRendererBackgrounds(true);

Answer 2

thnx for the answer i solved it by making a container and butting two labels inside it one for the value and the other for the rate icon and give the container a layout and return the container in the getListCellRendererComponent() method
