java - 删除 lwuit 列表中的索引

Question

我已经使用 LWUIT 创建了列表。
但它向我展示了带有索引的项目。
像

1. 项目-1
2. 项目-2
3. 第 3 项

我想删除左侧索引 1,2,3 我该怎么做？

代码：

 class mainForm extends Form implements ActionListener{

        List list;

        String newkey = "";
        final String COMPANY[] = {"AIRCEL", "AIRTEL", "BPL", "BSNL", "IDEA", "RELIANCE", "TATA DOCOMO", "TATA INDICOM", "UNINOR", "VIRGIN", "VIDEOCON", "VODAFONE", "AIRCEL1", "AIRTEL2", "BPL1", "BSNL1", "IDEA1", "RELIANCE1", "TATA DOCOMO1", "TATA INDICOM1", "UNINOR1", "VIRGIN1", "VIDEOCON1"};
        final int CO_LENGTH = COMPANY.length;

        mainForm() {

            super("Main Form");
            setLayout(new BoxLayout(BoxLayout.Y_AXIS));

            list = new List(COMPANY);
           list.addActionListener(this);


            list.setPreferredW(getWidth());

            addComponent(list);



        }
}

谢谢你。

Answer 1

尝试：

list.setListCellRenderer(new DefaultListCellRenderer(false));

javadocs解释了错误“showLineNumbers”的原因

Answer 2

试试这个——

private static class RemoveIndexRenderer extends Label implements ListCellRenderer {

    public RemoveIndexRenderer() {
        super("");
    }

    public Component getListCellRendererComponent(List list, Object value, int index, boolean isSelected) {
        setText(value.toString());
        setFocus(isSelected);
        getStyle().setBgTransparency(100);
        return this;
    }

    public Component getListFocusComponent(List list) {
        setText("");
        setFocus(true);
        getStyle().setBgTransparency(100);
        return this;
    }
}

和 -

    List list = new List(listModel);
    RemoveIndexRenderer listCellRenderer = new RemoveIndexRenderer();
    list.setListCellRenderer(listCellRenderer);
