救命！List列出图像名后，选择后怎么显示？<可以进行选择了，不会显示>
//list.java
//这个程序是很臭的

import   javax.microedition.midlet.*;
import   javax.microedition.lcdui.*;

public   class   list   extends   MIDlet   implements   CommandListener   {
private       Display   display;
private   Form   form;
private   List   list;
private   Alert   alert;
private   TextBox   textbox;
private   Image   image;
public   list()   {
//   TODO   自动生成构造函数存根
form=new   Form( "Form ");
list=new   List( "List ",List.TEXT_WRAP_ON);
alert=new   Alert( "Alert ", "警告! ",null,null);
try{
image=Image.createImage( "/ai.png ");
}
catch(Exception   e)
{

}
textbox=new   TextBox( "TextBox ", "文本 ",256,0);
display=Display.getDisplay(this);
}
protected   void   destroyApp(boolean   arg0)   throws   MIDletStateChangeException   {
//   TODO   自动生成方法存根

}

protected   void   pauseApp()   {
//   TODO   自动生成方法存根

}

protected   void   startApp()   throws   MIDletStateChangeException   {
//   TODO   自动生成方法存根
display=Display.getDisplay(this);
display.setCurrent(list);
list.setCommandListener(this);
list.append(new   String( "爱 "),image);
list.append(new   String( "爱 "),image);
//list.set(1,new   String( "爱 "),   image);

}
public   void   commandAction(Command   c,Displayable   d)
{
if(d.equals(list))
{
if(c==list.SELECT_COMMAND)
{
list.getSelectedIndex();
display.setCurrent(list);
list.append(null,   image);
}
}
}
}


------解决方案--------------------
用switch语句
