小弟菜鸟一个 刚接触ME不久 有点问题想请教大家~
问题来了（要怎样改？）：
正在生成 "Chapter02"
C:UsersKevinj2mewtk2.5.2appsChapter02srcFirstMIDlet.java:4: FirstMIDlet 不是抽象的，并且未覆盖 javax.microedition.lcdui.CommandListener 中的抽象方法 commandAction(javax.microedition.lcdui.Command,javax.microedition.lcdui.Displayable)
public class FirstMIDlet extends MIDlet implements CommandListener
^
1 错误
com.sun.kvem.ktools.ExecutionException
生成失败
原码：
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
public class FirstMIDlet extends MIDlet implements CommandListener
{
protected void startApp()
{
Display display = Display.getDisplay(this);
TextBox text = new TextBox ("hahaha","haha",127,TextField.ANY);
Command cmdExit = new Command("close",Command.EXIT,0);
text.addCommand(cmdExit);
text.setCommandListener(this);
display.setCurrent(text);
}
protected void pauseApp(){}
protected void destroyApp(boolean undicational){}
public void commandAction(Command cmd,Displayable d){
if(cmd.getCommandType()==Command.EXIT)
{
notifyDestroyed();
}
}
}
