import javax.microedition.lcdui.*;

public class TextFieldMIDlet extends MIDlet implements CommandListener {

    private Command exitComm;
    private TextField text;
    private Display display;

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

        text = new TextField("姓名", "张三", 10, TextField.ANY);
    }

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

        form.append(text);
        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();
        }

    }

}
