如何在android中暂停计时器？

Question

关于android中的计时器应用程序,我已经浏览了http://dewful.com/?tag=basic-android-timer链接.它工作正常.我需要添加暂停按钮来停止计时器和播放按钮再次从我停止的位置启动计时器.我可以完成这项任务吗？

我的代码:

long timervalue = 50000;
CountDownTimer Counter1 = new CountDownTimer(timervalue, 1000)
{
    public void onTick(final long millisUntilFinished)
    {
        time.setText(formatTime(millisUntilFinished));
        pause.setOnClickListener(new View.OnClickListener()
        {
            public void onClick(View v)
            {
                Counter1.cancel();
            }
        }
        );
        resume.setOnClickListener(new View.OnClickListener()
        {
            public void onClick(View v)
            {
                Counter1.start();
                timervalue = Long.parseLong(output);
                System.out.println("paused timer value resumed"+timervalue);
                Counter1.onTick(timervalue);
            }
        }
        );
    }
    public void onFinish()
    {
        Counter1.cancel();
    }
};
public String formatTime(long millis)
{
    output = "00";
    seconds = millis / 1000;
    seconds = seconds % 60;
    System.out.println("seconds here"+seconds);
    String secondsD = String.valueOf(seconds);
    System.out.println("secondsD here"+secondsD);
    if (seconds <
    10)             secondsD = "0" + seconds;
    System.out.println("secondsD here in if"+secondsD);
    output = secondsD;
    return output;
}

在上面的代码中,当单击恢复按钮时,计时器再次从50秒开始,我不希望这样.它应该从我暂停的时间开始.关于这个请帮帮我......我一周以来一直在努力......

非常感谢帮助..........

public class TimerActivity extends Activity

    EditText e1;
    MyCount counter;
    Long s1;
    /** Called when the activity is first created. */ 
    @Override
    public void onCreate(Bundle savedInstanceState)

        counter= new MyCount(5000,1000);
        counter.start();
    }
    public void asdf(View v)
    {
        switch(v.getId())
        {
            case R.id.button1:         counter.cancel();
            break;
            case R.id.button2:         counter= new MyCount(s1,1000);
            counter.start();
        }
    }
    public class MyCount extends CountDownTimer
    {

        {
            super(millisInFuture, countDownInterval);
        }
        @Override     public void onFinish()
        {
            e1.setText("DONE");
        }
        @Override     public void onTick(long millisUntilFinished)
        {
            s1=millisUntilFinished;
            e1.setText("left:"+millisUntilFinished/1000);
