datafielddemo.java

这是我收集的别人写的关于基本控件的例子

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

public class DataFieldDemo extends MIDlet implements CommandListener {
	private final static Command exitCommand = new Command("Exit", Command.EXIT, 1);

	private boolean firstTime;

	private Form mainForm;

	public DataFieldDemo() {
		mainForm = new Form("DateField");
	}

	protected void startApp() {
        mainForm.append(new DateField("时间", DateField.DATE));
		mainForm.addCommand(exitCommand);
		mainForm.setCommandListener(this);
		Display.getDisplay(this).setCurrent(mainForm);
	}

	protected void destroyApp(boolean unconditional) {
	}

	protected void pauseApp() {
	}

	public void commandAction(Command c, Displayable d) {
		if (c == exitCommand) {
			destroyApp(false);
			notifyDestroyed();
		}
	}
}
