我正在構建一個倒數計時器應用程序,我讓用戶按下一個按鈕來啓動計時器。當按下按鈕時,定時器倒計時(工作會話)。然後,用戶可以通過點擊相同的按鈕(重新標記爲「重置」)來等待定時器完成或重置定時器。onClick方法不會啓動我的CountDownTimer - 爲什麼?
如果他們等待計時器結束,另一個計時器啓動(短時間間隔 - 又名休息時間)。此時,如果他們按下按鈕(重新標記爲「結束休息」),它將取消休息計時器並啓動另一個工作會話。
由於某些原因,當我點擊我的按鈕時,它不會啓動計時器。在我目前的代碼設置。我測試了計時器和按鈕,我知道他們工作。
出於某種原因,我的onClick方法不啓動計時器,任何幫助?我必須對CountDownTimer類做些什麼嗎?
public class SimplyPomodoroActivity extends Activity implements OnClickListener {
TextView tvTimer; // used to update timer...
Button btStart; //main button
Vibrator vibrator; // vibrate when button is pressed..
boolean off = true;
boolean working = false;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
initialiaze(); //connect xml to java code and setup listener

shortBreakCounter.start();
}

};
CountDownTimer longBreakCounter = new CountDownTimer(longBreak, 1000) {
public void onTick(long millisUntilFinished) {
displayRemainingTime(millisUntilFinished);

public void onFinish() {
pomoIncrement();
}
};
private void pomoIncrement() {
// increment by one, reset at 8
pomoCount += (pomoCount > 8) ? -pomoCount : 1;
}
private void displayRemainingTime(long millisUntilFinished) {
// TODO Auto-generated method stub
int sec = (int) (millisUntilFinished/1000) % 60;
int min = (int) ((millisUntilFinished/1000)/60);
tvTimer.setText("" + min + ":" + sec);
}
}
我的倒計時器將不是我的,如果(關閉){...}語句開始......當我周圍改成了其他配置也不會取消我的當前運行CountDownTimer ..
控制是否超越了這種說法? vibrator.vibrate(V); – kosa 2012-04-10 14:32:29
好像你的按鈕點擊不正常。你記錄了點擊事件嗎? – waqaslam 2012-04-10 14:33:46
