使用SwingWorker设置坐标

Question

现在我完全被一个涉及WorldWind的项目困住了，但这是SwingWorker和swing Timer类的一个普遍问题。

基本上，我在一个地球仪上有一个形状，它有一个拉特朗坐标，每一段时间，我试图沿着拉特朗的一个预定向量移动它。除了实际的计时器事件之外，一切都应该正常工作。我试过使用多个东西从一个标准的计时器，调用System.getCurrentTimeMill()和递增，和他们都没有工作。

现在，当我点击"动画"按钮时它会调用这个函数:

private void animate(LatLon pos) throws InvocationTargetException, InterruptedException   {
        // TODO Auto-generated method stub
        if(SwingUtilities.isEventDispatchThread())
        {
            timer = new Timer(speed, this);
            timer.setInitialDelay(pause);
            timer.setRepeats(false);
            while (count < 5)
            {
                timer.start();
                CircleWorker.execute();
                sphere.setLocation(pos);
                count ++;
            }
        }
    else{
            SwingUtilities.invokeAndWait(new Runnable()
            {
                @Override
                public void run(){
                    int count = 0;
                    //timer = new Timer(speed, this);
                    timer.setInitialDelay(pause);
                    while (count < 30)
                    {
                        timer.start();
                        CircleWorker.execute();
                        count ++;
                        checker2();
                    }
                }});

这是我的SwingWorker:

SwingWorker<LatLon, Void> CircleWorker = new SwingWorker<LatLon, Void>()
            {

                @Override
                protected LatLon doInBackground() 
                {
                    //checker();

                    double lat = changeAm.getLatitude().getDegrees() + currentPos.getLatitude().getDegrees();
                    double lon = changeAm.getLongitude().getDegrees() + currentPos.getLongitude().getDegrees();
                    // sets lat lon to the amounts in each individual amount
                    currentPos = LatLon.fromDegrees(lat, lon);
                    counter ++;
                    //checker2();
                    return currentPos;
                }
                @Override
                public void done()
                {
                    //checker3();
                    currentPos = ATLANTA;
                }
            };

我已经完全更改了代码，不再使用swing worker，只使用swing Timer和一个动作事件。我的对象正在移动，问题是我无法控制这个事件发生多少次。我想在执行了30次或100次或任意次数后停止它。

当前代码:

    private void animate() throws InvocationTargetException, InterruptedException   {
        // TODO Auto-generated method stub
        currentPos = ATLANTA;

        ActionListener sphereAction  = new ActionListener()
        {
            private int count = 0;
            @Override
            public void actionPerformed(ActionEvent evt) 
            {
                double lat = changeAm.getLatitude().getDegrees() + currentPos.getLatitude().getDegrees();
                double lon = changeAm.getLongitude().getDegrees() + currentPos.getLongitude().getDegrees();
                // sets lat lon to the amounts in each individual amount
                currentPos = LatLon.fromDegrees(lat, lon);

                //checker2();
                sphere.setLocation(currentPos); 
                setCount(getCount() + 1);
            }
            public int getCount() {
                return count;
            }
            public void setCount(int count) {
                this.count = count;
            }
        };
        Timer timer = new Timer(speed, sphereAction);
        timer.start();
        //Obviously this isn't working.
        if (count == 10)
            timer.stop();
