j2me接口的例子,很不错的东东 可以做教程

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

public class TickerMIDlet extends MIDlet implements CommandListener {

    private Command exitComm;

    private Display display;

    public TickerMIDlet() {
        display = Display.getDisplay(this);
        exitComm = new Command("离开", Command.EXIT, 1);
    }

    public void startApp() {
        TextBox t = new TextBox("Hello",
                                "你好!", 256, 0);
        Ticker ticker = new Ticker("从绝望中寻找希望！");
        t.setTicker(ticker);
        t.addCommand(exitComm);
        t.setCommandListener(this);

        display.setCurrent(t);
    }

    public void pauseApp() {}

    public void destroyApp(boolean unconditional) {}

    public void commandAction(Command c, Displayable s) {
    	
    	String comm = c.getLabel();
    	
        if (comm.equals("离开")) {
            destroyApp(false);
            notifyDestroyed();
        }
    }
}
