gaugedemo_2.java

1.显示进度条的用法. 2.刚学j2me是一个不错的实例.

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

public class gaugeDemo_2 extends MIDlet implements CommandListener {
	private Command exitCommand;

	private Form mainform;

	private GaugeThread gthread;

	public gaugeDemo_2() {
		exitCommand = new Command("Exit", Command.EXIT, 1);
		mainform = new Form("gauge实例");

		mainform.addCommand(exitCommand);
		mainform.setCommandListener(this);

		gthread = new GaugeThread("后台自动增加",40,0);
		//new Thread(gthread).start();
		
		mainform.append(gthread);
		mainform.get(0).setLayout(Item.LAYOUT_EXPAND|Item.LAYOUT_NEWLINE_AFTER);

	}

	protected void startApp() throws MIDletStateChangeException {
		Display.getDisplay(this).setCurrent(mainform);
	}

	protected void pauseApp() {
	}

	protected void destroyApp(boolean p1) {
		gthread.setDone();
	}

	public void commandAction(Command c, Displayable d) {

			destroyApp(false);
			notifyDestroyed();
