一个简单的java秒表java计时器，用java语言写的，android开发

下面是一个实例，我吧主要的代码都放在这里了，可以看下：

public static Runnable refreshRunnable = new Runnable() {@Overridepublic void run() {// TODO Auto-generated method stubcurrentTime = new Date(System.currentTimeMillis());while (SETTIME == true) {hh = currentTime.getHours();mm = currentTime.getMinutes();ss = currentTime.getSeconds();SETTIME = false;}currentTime.setHours(hh);currentTime.setMinutes(mm);currentTime.setSeconds(ss);endTime = new Date(System.currentTimeMillis()- currentTime.getTime() - 8 * 60 * 60 * 1000);currentTime = endTime;// 对系统当前时间进行格式化String FormatcurrentDate = simpleDateFormat.format(currentTime);callWindowText2.setText(FormatcurrentDate);}};

public void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);NewCallButton = (Button) findViewById(R.id.new_call);NewCallButton.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubsimpleDateFormat = new SimpleDateFormat(" HH:mm:ss");handler = new Handler();myThread = new Thread() {public void run() {while (ALWAYS == true && KEY_Dnow == true) {handler.post(refreshRunnable);try {Thread.sleep(1000);} catch (InterruptedException e) {e.printStackTrace();}}}};myThread.start();}});

由于System.currentTimeMillis()获取的时间是从8:00开始的，所以后面要减去它，就可以实现一个从00:00:00开始计时的工具
