Я пытаюсь создать таймер обратного отсчета в android. В этом примере я вводил несколько минут в качестве параметра, который отображается в таймере обратного отсчета.
Проблема заключается в том, что когда я вводю минуты, например 65, то счетчик будет 65:00. Я бы хотел, чтобы счетчик показывал 1:05:00 то есть в формате HH: MM: SS.
public class MainActivity extends Activity implements OnClickListener {
private Button buttonStartTime, buttonStopTime;

private CountDownTimer countDownTimer; // built in android class
// CountDownTimer

// milliseconds
private long timeBlinkInMilliseconds; // start time of start blinking
private boolean blink; // controls the blinking .. on and off
