Java XDEVTextField';s值为';t实时更新

Java XDEVTextField';s值为';t实时更新,java,date,time,timer,rapidclipse,Java,Date,Time,Timer,Rapidclipse,我有一个XDEVTextField,需要每秒实时更新一次。我尝试了问题中提出的答案,包括使用Executor和Swing Timer。我也试过了。 下面是我的代码: public class FirstView extends XdevView implements Runnable { Thread t = null; String timeString = ""; public FirstView() { super();

我有一个XDEVTextField,需要每秒实时更新一次。我尝试了问题中提出的答案,包括使用Executor和Swing Timer。我也试过了。
下面是我的代码:

public class FirstView extends XdevView implements Runnable {
    Thread t = null;
    String timeString = "";

    public FirstView() {
        super();
        this.initUI();
        this.t = new Thread(this);
        this.t.start();
    }

    @Override
        public void run() {
            // TODO Auto-generated method stub
            try {
                 while (true) {
                    final Calendar cal = Calendar.getInstance();
                    final SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
                    final Date date = cal.getTime();
                    this.timeString = formatter.format(date);
                    System.out.println(this.timeString);
                    this.txtTime.setValue(this.timeString);
                    Thread.sleep(500); <-- this should be changed to 1000 but I forgot to
                 } 
              }
              catch (final Exception e) {
                  e.printStackTrace();
              }
        }
public类FirstView扩展XdevView实现可运行{
线程t=null;
字符串timeString=“”;
公共第一视图(){
超级();
this.initUI();
this.t=新线程(this);
这个.t.start();
}

公开募捐{
//TODO自动生成的方法存根
试一试{
while(true){
最终日历cal=Calendar.getInstance();
最终SimpleDataFormat格式化程序=新SimpleDataFormat(“dd/MM/yyyy HH:MM:ss”);
最终日期=cal.getTime();
this.timeString=formatter.format(日期);
System.out.println(this.timeString);
this.txtTime.setValue(this.timeString);

sleep(500);您只能使用access()方法访问UI,该方法会锁定会话以防止冲突

@Override
    public void run() {
        try {
            while (true) {
                this.time = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss").format(new Date());
                System.out.println(this.time);
                UI.getCurrent().access(()->this.button.setCaption(this.time));
                this.t.sleep(1000);
                
            }
        } catch (final InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
