Countdown-Timer für Android

Question

Kann mir hier jemand mit diesem Code helfen? Es funktioniert, aber wenn der Countdown-Timer beendet ist, schließt es meine Apps. Ich möchte, dass "Finish" im Text angezeigt wird. Aber die Kodierung für onFinish, die ich verwendet habe, scheint nicht praktikabel.

public class SimpleCountdowTimer extends CountDownTimer { 
public static int oneSecond = 1000; 
TextView statusTextView; 
ProgressBar mprogressBar, mprogressBar1; 
Button startTimerButton; 
Button stopTimerButton, pauseTimerButton, resumeTimerButton; 
private long timeRemaining = 0; 

public SimpleCountdowTimer(long millisInFuture, long countDownInterval, 
          TextView statusTextView, ProgressBar mprogressBar, ProgressBar mprogressBar1) { 

    super(millisInFuture, countDownInterval); 

    this.statusTextView = statusTextView; 
    this.mprogressBar1 = mprogressBar1; 
    this.mprogressBar = mprogressBar; 
} 

@Override 
public void onTick(long millisInFuture) { //do something in every tick 

     //Put count down timer remaining time in a variable 
     statusTextView.setText(String.valueOf(millisInFuture/ oneSecond)); 
     long millis = millisInFuture; 
     timeRemaining = millisInFuture; 
     long countDownInterval = 1000; 
     mprogressBar1.setProgress((int) (millisInFuture)); 
     //Convert milliseconds into hour,minute and seconds 
     String hms = String.format("%02d:%02d:%02d", TimeUnit.MILLISECONDS.toHours(millis), TimeUnit.MILLISECONDS.toMinutes(millis) - TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)), TimeUnit.MILLISECONDS.toSeconds(millis) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis))); 
     statusTextView.setText(hms);//set text 
    } 

@Override 
public void onFinish() { 
     statusTextView.setText("00:00:00"); 
     mprogressBar.setVisibility(View.VISIBLE); 
     mprogressBar1.setVisibility(View.VISIBLE); 
     //Disable the pause, resume and cancel button 
     pauseTimerButton.setEnabled(false); 
     resumeTimerButton.setEnabled(false); 
     stopTimerButton.setEnabled(false); 
     //Enable the start button 
     startTimerButton.setEnabled(true); 
} 
}

Why don't you use this way : 

    CountDownTimer cdt = new CountDownTimer(10000, 1000) { 

      @Override 
      public void onTick(long millisUntilFinished) { 
       statusTextView.setText(String.valueOf(millisInFuture/ oneSecond)); 
     long millis = millisInFuture; 
     timeRemaining = millisInFuture; 
     long countDownInterval = 1000; 
     mprogressBar1.setProgress((int) (millisInFuture)); 
     //Convert milliseconds into hour,minute and seconds 
     String hms = String.format("%02d:%02d:%02d", TimeUnit.MILLISECONDS.toHours(millis), TimeUnit.MILLISECONDS.toMinutes(millis) - TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)), TimeUnit.MILLISECONDS.toSeconds(millis) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis))); 
     statusTextView.setText(hms);//set text 
      } 

      @Override 
      public void onFinish() { 
       statusTextView.setText("00:00:00"); 
     mprogressBar.setVisibility(View.VISIBLE); 
     mprogressBar1.setVisibility(View.VISIBLE); 
     //Disable the pause, resume and cancel button 
     pauseTimerButton.setEnabled(false); 
     resumeTimerButton.setEnabled(false); 
     stopTimerButton.setEnabled(false); 
     //Enable the start button 
     startTimerButton.setEnabled(true); 
      } 
     }; 

     cdt.start();
