main.java

这是我第一次开始尝试J2ME平台的程序编写

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

public class Main extends MIDlet implements CommandListener{
	protected CanvasTest ct;
	protected Display display;
	protected TextBox tb;
	protected Command exitCommand = new Command("Exit",Command.EXIT,1);
	public Main() {
		super();
		// TODO 自动生成构造函数存根
	}

	protected void startApp() throws MIDletStateChangeException {
		// TODO 自动生成方法存根
		tb = new TextBox(null,"asdfasdf",10,TextField.ANY);
		ct = new CanvasTest();
		ct.addCommand(exitCommand);
		ct.setCommandListener(this);
		display = Display.getDisplay(this);
		display.setCurrent(ct);
	}

	protected void pauseApp() {
		// TODO 自动生成方法存根

	}

	protected void destroyApp(boolean arg0) throws MIDletStateChangeException {
		// TODO 自动生成方法存根

	}
	public void commandAction(Command c,Displayable d){
		if(d == ct && c == exitCommand){
			try{
				destroyApp(false);
			}
			catch(Exception e){}
			notifyDestroyed();
		}
	}
}
