標題: 請各位幫幫忙(倒數計器修正)

請問各位大大
倒數計時需要加入甚麼指令，才能讓他停止且停止後能恢復上次繼續倒數

public class MainActivity extends Activity implements OnClickListener
{
      private static final String tag = "Main";
      private MalibuCountDownTimer countDownTimer;
      private long timeElapsed;
      private boolean timerHasStarted = false;
      private Button startB;
      private TextView text;
      private TextView timeElapsedView;
      //開始時間
      int startTime = 50000;
      //每秒
      int  interval = 1000;

      /** Called when the activity is first created. */
      @Override
      public void onCreate(Bundle savedInstanceState)
         {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            startB = (Button) this.findViewById(R.id.button);
            startB.setOnClickListener(this);

            text = (TextView) this.findViewById(R.id.timer);
            timeElapsedView = (TextView) this.findViewById(R.id.timeElapsed);
            countDownTimer = new MalibuCountDownTimer(startTime, interval);
            text.setText(text.getText() + String.valueOf(startTime));
         }

      @Override
      public void onClick(View v)
         {
            if (!timerHasStarted)
                  {
                     countDownTimer.start();
                     timerHasStarted = true;
                     startB.setText("Start");
                  }
            else
                  {

                     countDownTimer.cancel();
                     timerHasStarted = false;
                     startB.setText("RESET");
                  }
         }

      // CountDownTimer class
      public class MalibuCountDownTimer extends CountDownTimer
         {

            public MalibuCountDownTimer(int  startTime, int  interval)
                  {
                     super(startTime, interval);
                  }

            @Override
            public void onFinish()
                  {
                     text.setText("Time's up!");
                     timeElapsedView.setText("Time Elapsed: " +startTime);
                  }

            @Override
            public void onTick(long millisUntilFinished)
                  {
//
//                timeElapsedView.setText("seconds remaining:" + millisUntilFinished
// / 1000);
                     text.setText("Time remain:" + millisUntilFinished);
                     timeElapsed = startTime - millisUntilFinished;
                     timeElapsedView.setText("Time Elapsed: " + timeElapsed);
                  }
         }
}

指令我忘記了，畢竟我好久沒寫了，你就設定一個迴圈DO LOOP之類的，時間到0時loop回程式起始點就可以了
幫得上忙的話。記得給我碎鑽
