使用j2me提供的低级UI:CanvasImage和Graphics对象来绘制九宫格,

2.九宫格布局为主题区和底部菜单区
3.将一张240*320的图片设置为背景图
4.根据屏幕宽高计算出各图标的位置，然后绘制各图标。
具体效果，如图所示：
 

核心代码如下：

public static final String[] filenames = { "/01.png", "/02.png", "/03.png",
   "/04.png", "/05.png", "/06.png" };
public static final String[] labels = { "公文推送", "通知公告", "日程安排", "通讯录查询",
   "会议室查询", "手机邮箱" };
public Image[] icons = new Image[9];

public void paint(Graphics g) {
  int cw = this.getWidth();
  int ch = this.getHeight();
  try {
   // paintHead(g);
   this.setFullScreenMode(true);
   Image img = Image.createImage("/sliderbgn.JPG");
   // g.drawImage(img,0, 0, Graphics.TOP|Graphics.LEFT);
   g.drawImage(img, 0, 0, Graphics.TOP
     | Graphics.LEFT);

   for (int i = 0; i < filenames.length; i++) {
    try {
     icons[i] = Image.createImage(filenames[i]);
    } catch (IOException ex) {

    }
   }
   int old_color = g.getColor();
   g.setColor(0xffffff);
      int startY=ch/4;

   for (int i = 0; i < 2; i++) {
    for (int j = 0; j < 3; j++) {

     g.drawImage(icons[i * 3 + j], j * cw / 3 + 10, startY+i * ch*3 / 10,
       Graphics.TOP | Graphics.LEFT);
     g.drawString(labels[i * 3 + j], j * cw / 3 + 30, startY+i * ch*3 / 10
        + icons[i].getHeight(),
       Graphics.HCENTER | Graphics.TOP);
    

    }
   }
  

   g.setColor(old_color);
   paintBottom(g);
  } catch (Exception ex) {
   System.out.println(ex.toString());
  }
}
