如何在android中暂停计时器？

Question

我已经通过链接http://dewful.com/?tag=basic-android-timer关于android中的计时器应用程序。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以从我停止的地方再次启动计时器。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; 
} 

在当恢复按钮被点击的计时器再次从50秒开始，我不希望像上面的代码。它应该从我暂停的那一刻开始。请帮我对此...我为这个苦苦挣扎，因为1周......

将是帮助真的很感谢..........

public class TimerActivity extends Activity 
{ 
    EditText e1; 
    MyCount counter; 
    Long s1; 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
     e1=(EditText)findViewById(R.id.editText1); 
     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 
    { 
     public MyCount(long millisInFuture, long countDownInterval) 
     { 
      super(millisInFuture, countDownInterval); 
     } 
     @Override  public void onFinish() 
     { 
      e1.setText("DONE"); 
     } 
     @Override  public void onTick(long millisUntilFinished) 
     { 
      s1=millisUntilFinished; 
      e1.setText("left:"+millisUntilFinished/1000); 
     } 
    } 
} 

Answer 2

public void time(long m){ 
    timer=new CountDownTimer(m, 1000) { 

      public void onTick(long millisUntilFinished) { 

       tv_timer.setText(formatTime(millisUntilFinished)); 

      } 

      public void onFinish() { 
       tv_timer.setText("done!"); 
      } 

     }.start(); 

} 

我已经使用这个定时器和我已经把按钮暂停和使用该

case R.id.bT_PAUSE: 
    String s_time = null; 

    try{ 
    if(Bt_pause.getText().equals("PAUSE")){ 

    s_time=tv_timer.getText().toString(); 
    timer.cancel(); 
    String[] Pause_time=s_time.split(":"); 
    m=Long.parseLong(Pause_time[0].trim()); 
    n=Long.parseLong(Pause_time[1].trim()); 
    m=(m*60)+n; 
    m=m*1000; 
    Bt_pause.setText("RESUME"); 

    }else if(Bt_pause.getText().equals("RESUME")){ 
     //min_longmillis=Long.parseLong(sss); 
     //min_longmillis=min_longmillis*1000*60; 
     //min_longmillis=m; 
     //timer.start(); 
     Toast.makeText(this,String.valueOf(m),Toast.LENGTH_SHORT).show(); 
     time(m); 
     Bt_pause.setText("PAUSE"); 
    } 
    }catch(Exception e){ 
     Toast.makeText(this,e.toString(),Toast.LENGTH_SHORT).show(); 
    } 
    break; 

这对于数据的时间

public String formatTime(long millis) { 
    String output = "00:00"; 
    long seconds = millis/1000; 
    long minutes = seconds/60; 

    seconds = seconds % 60; 
    minutes = minutes % 60; 

    String sec = String.valueOf(seconds); 
    String min = String.valueOf(minutes); 

    if (seconds < 10) 
     sec = "0" + seconds; 
    if (minutes < 10) 
     min= "0" + minutes; 

    output = min + " : " + sec; 
    return output; 
}//formatTime
