Java me 如何设置每个列表'；s命令组件，以便包含的对话框和命令之间没有空间'；什么短信？

有一个对话框，其中包含命令列表。当显示时，

公共组件getListFocusComponent（List List）

方法的标签呈现器和

公共组件getListCellRenderComponent的组件（List List，Object value，int index，boolean isSelected）

派生类的方法

DefaultListCellRenderer

没有占据对话框的全部宽度

那么，如何使标签和选择组件占据包含对话框的所有宽度呢

代码如下：

public class CMenu extends Dialog {
    private String disp;
    private List lCmds;
    public static Command retCommand;
    public CMenu(Command[] cmds, String disposition)
    {
        super();
        this.getStyle().setBorder(Border.createRoundBorder(10, 20));
        afficheCmd(cmds);
        this.setScrollableY(false);
        disp = disposition;
    }
    private void afficheCmd(Command[] cmds)
    {
        lCmds = new List(cmds);
        lCmds.setListCellRenderer(new TickerRenderer());
        lCmds.setCommandList(true);
        lCmds.setPreferredW(this.getPreferredW());
        lCmds.setFixedSelection(List.FIXED_NONE_CYCLIC);
        ((DefaultListCellRenderer)lCmds.getRenderer()).setShowNumbers(false);
        this.addComponent(lCmds);
        lCmds.setSelectedIndex(0);
        lCmds.requestFocus();
    }
    protected void onShow()
    {
        lCmds.setSelectedIndex(0);
        lCmds.requestFocus();
    }
    public void affiche()
    {
        int top = Display.getInstance().getDisplayHeight() - lCmds.getHeight();
        if (disp.equalsIgnoreCase("gauche"))
        {
            this.show(top, 0, 0, 100, false);
        }
        else
        {
            this.show(top, 0, 100, 0, false);
        }
        lCmds.requestFocus();
        lCmds.setSelectedIndex(0);
    }
    protected void actionCommand(Command cmd)
    {
        retCommand = cmd;
        this.dispose();
    }
}

class TickerRenderer extends DefaultListCellRenderer {

    private DefaultListCellRenderer selectedRenderer = new DefaultListCellRenderer(false);
    private List parentList;

    public TickerRenderer() {
        super(false);
    }

    public boolean animate() {
        if (parentList != null && parentList.getComponentForm() != null) {
            if (selectedRenderer.isTickerRunning()) {
                if (selectedRenderer.animate()) {
                    parentList.repaint();
                }
            }
        }
        return super.animate();
    }

    public Component getListCellRendererComponent(List list, Object value, int index, boolean isSelected)
    {
        if (isSelected)
        {
            (selectedRenderer.getListCellRendererComponent(list, value, index, isSelected)).getSelectedStyle().setBgTransparency(0);
            (selectedRenderer.getListCellRendererComponent(list, value, index, isSelected)).getUnselectedStyle().setBgTransparency(0);

            (selectedRenderer.getListCellRendererComponent(list, value, index, isSelected)).getSelectedStyle().setFgColor(16777215);
            (selectedRenderer.getListCellRendererComponent(list, value, index, isSelected)).getUnselectedStyle().setFgColor(0);

            if (index == list.getSelectedIndex())
            {
                if (selectedRenderer.shouldTickerStart())
                {
                    if (!selectedRenderer.isTickerRunning())
                    {
                        parentList = list;
                        list.getComponentForm().registerAnimated(this);
                        selectedRenderer.startTicker(UIManager.getInstance().getLookAndFeel().getTickerSpeed(), true);
                    }
                }
                else
                {
                    if (selectedRenderer.isTickerRunning())
                    {
                        selectedRenderer.stopTicker();
                    }
                }
            }
            return selectedRenderer;
        }
        else
        {
            return super.getListCellRendererComponent(list, value, index, isSelected);
        }
    }
    public Component getListFocusComponent(List list) {
        Label label = new Label("");
        label.getStyle().setBgTransparency(255);
        label.getStyle().setBgColor(205388);
        label.getStyle().setBorder(Border.createRoundBorder(5, 10, 16777215));
        return label;
    }
}

好的，给你：

lCmds.getSelectedStyle().setPadding(0, 0, 0, 0);
lCmds.getUnselectedStyle().setPadding(0, 0, 0, 0);
this.getContentPane().getSelectedStyle().setPadding(0, 0, 0, 0);
this.getContentPane().getUnselectedStyle().setPadding(0, 0, 0, 0);
this.addComponent(lCmds);
