天文臺更新時間

Question

我有一個天文臺。應該顯示時間。當我開始計時器的時間總是相同的，但它應該更新

呼叫：

   Log.e("XXX","OnClick"); 
       String[] array = clock.getText().toString().split(":"); 
       int ms = (Integer.valueOf(array[0])*60 + Integer.valueOf(array[1]))*60000; 
       Log.e("XXX",String.valueOf(ms)); 
       MyTimer counter = new MyTimer(ms, 1000, Timer.this,clock); 

       counter.start(); 

定時器：

public class MyTimer extends CountDownTimer { 
    private Context con; 
    private Chronometer clock; 

    public MyTimer(long millisInFuture, long countDownInterval, Context context, Chronometer clock) { 
     super(millisInFuture, countDownInterval); 
     this.con = context; 
     this.clock= clock; 
     // TODO Auto-generated constructor stub 
    } 


    @Override 
    public void onTick(long millisUntilFinished) { 

     int seconds = (int) (millisUntilFinished/1000) % 60 ; 
     int minutes = (int) ((millisUntilFinished/(1000*60)) % 60); 
     int hours = (int) ((millisUntilFinished/(1000*60*60)) % 24); 
     clock.setText(String.format("%02d:%02d:%02d", hours,minutes,seconds)); 
     Log.e("Timer", String.valueOf(millisUntilFinished)); 

    } 

的問題是，在天文鐘的時間總是相同。並且日誌（定時器） 也不會出現。難道是UI的刷新過快？

對於將您的上下文和視圖作爲擴展類的參數進行傳遞，我並不十分有信心。也許你應該嘗試這種適應你的代碼（並擺脫你的MyTimer類）？

Log.e("XXX","OnClick"); 
String[] array = clock.getText().toString().split(":"); 
int ms = (Integer.valueOf(array[0])*60 + Integer.valueOf(array[1]))*60000; 
Log.e("XXX",String.valueOf(ms)); 

new CountDownTimer(ms,1000){ 
    @Override 
    public void onTick(long millisUntilFinished) { 

     int seconds = (int) (millisUntilFinished/1000) % 60 ; 
     int minutes = (int) ((millisUntilFinished/(1000*60)) % 60); 
     int hours = (int) ((millisUntilFinished/(1000*60*60)) % 24); 
     clock.setText(String.format("%02d:%02d:%02d", hours,minutes,seconds)); 
     Log.e("Timer", String.valueOf(millisUntilFinished)); 

    } 
}.start();
