gaugemidlet.java

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 GaugeMIDlet extends MIDlet implements CommandListener {

    private Command exitComm;

    private Gauge activeGauge;
    private Gauge inactiveGauge;

    private Display display;

    public GaugeMIDlet() {
        display = Display.getDisplay(this);

        exitComm = new Command("离开", Command.EXIT, 1);

        activeGauge = new Gauge("可调整:", true, 10, 2);
        inactiveGauge = new Gauge("不可调整:", false, 10, 4);

    }

    public void startApp() {
        Form form = new Form("Gauge 示范");

        form.append(activeGauge);
        form.append(inactiveGauge);

        form.addCommand(exitComm);
        form.setCommandListener(this);
        display.setCurrent(form);
    }

    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();
        }

    }

}
