Minutnik w GG: MM: format SS w Androidzie

Question

Próbuję opracować zegar odliczający w systemie Android. W tym przykładzie wprowadzam liczbę minut jako parametr, który jest pokazany w odliczającym czasomierzu.

Problem polega na tym, że po wprowadzeniu minut, na przykład 65, , licznik będzie 65:00. Chciałbym, aby licznik pokazał 1:05:00 , tj. W formacie HH: MM: SS.

public class MainActivity extends Activity implements OnClickListener { 

private Button buttonStartTime, buttonStopTime; 
private EditText edtTimerValue; 
private TextView textViewShowTime; // will show the time 
private CountDownTimer countDownTimer; // built in android class 
             // CountDownTimer 
private long totalTimeCountInMilliseconds; // total count down time in 
              // milliseconds 
private long timeBlinkInMilliseconds; // start time of start blinking 
private boolean blink; // controls the blinking .. on and off 

/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    buttonStartTime = (Button) findViewById(R.id.btnStartTime); 
    buttonStopTime = (Button) findViewById(R.id.btnStopTime); 
    textViewShowTime = (TextView) findViewById(R.id.tvTimeCount); 
    edtTimerValue = (EditText) findViewById(R.id.edtTimerValue); 

    buttonStartTime.setOnClickListener(this); 
    buttonStopTime.setOnClickListener(this); 

} 

@Override 
public void onClick(View v) { 
    if (v.getId() == R.id.btnStartTime) { 
     textViewShowTime.setTextAppearance(getApplicationContext(), 
       R.style.normalText); 
     setTimer(); 
     buttonStopTime.setVisibility(View.VISIBLE); 
     buttonStartTime.setVisibility(View.GONE); 
     edtTimerValue.setVisibility(View.GONE); 
     edtTimerValue.setText(""); 
     startTimer(); 

    } else if (v.getId() == R.id.btnStopTime) { 
     countDownTimer.cancel(); 
     buttonStartTime.setVisibility(View.VISIBLE); 
     buttonStopTime.setVisibility(View.GONE); 
     edtTimerValue.setVisibility(View.VISIBLE); 
    } 
} 

private void setTimer() { 
    int time = 0; 
    if (!edtTimerValue.getText().toString().equals("")) { 
     time = Integer.parseInt(edtTimerValue.getText().toString()); 
    } else 
     Toast.makeText(MainActivity.this, "Please Enter Minutes...", 
       Toast.LENGTH_LONG).show(); 

    totalTimeCountInMilliseconds = 60 * time * 1000; 

    timeBlinkInMilliseconds = 30 * 1000; 
} 

private void startTimer() { 
    countDownTimer = new CountDownTimer(totalTimeCountInMilliseconds, 500) { 
     // 500 means, onTick function will be called at every 500 
     // milliseconds 

     @Override 
     public void onTick(long leftTimeInMilliseconds) { 
      long seconds = leftTimeInMilliseconds/1000; 

      if (leftTimeInMilliseconds < timeBlinkInMilliseconds) { 
       textViewShowTime.setTextAppearance(getApplicationContext(), 
         R.style.blinkText); 
       // change the style of the textview .. giving a red 
       // alert style 

       if (blink) { 
        textViewShowTime.setVisibility(View.VISIBLE); 
        // if blink is true, textview will be visible 
       } else { 
        textViewShowTime.setVisibility(View.INVISIBLE); 
       } 

       blink = !blink; // toggle the value of blink 
      } 

      textViewShowTime.setText(String.format("%02d", seconds/60) 
        + ":" + String.format("%02d", seconds % 60)); 
      // format the textview to show the easily readable format 

     } 

     @Override 
     public void onFinish() { 
      // this function will be called when the timecount is finished 
      textViewShowTime.setText("Time up!"); 
      textViewShowTime.setVisibility(View.VISIBLE); 
      buttonStartTime.setVisibility(View.VISIBLE); 
      buttonStopTime.setVisibility(View.GONE); 
      edtTimerValue.setVisibility(View.VISIBLE); 
     } 

    }.start(); 

} 
}

Używam poniższy kod przekonwertować z trwania w seconds do formatu HH:MM:SS.

String.format("%02d:%02d:%02d", durationSeconds/3600, 
       (durationSeconds % 3600)/60, (durationSeconds % 60)); 

można łatwo dostosować to wejście do zaakceptowania w minutes ale wówczas wyjściowy będzie w formacie HH:MM:00 ponieważ nie trzeba sekund, np:

String.format("%02d:%02d:%02d", durationMinutes/60, durationMinutes % 60, 0);
