Countdown timer in HH:MM:SS format in Android

Question

I am trying to develop a countdown timer in android. In this example I am entering a number of minutes as a parameter which is shown in a countdown timer. The problem is that when I am entering minutes, for example 65, then the counter will be 65:00. I would like the counter to show 1:05:00 i.e. in HH:MM:SS format. ``` 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.layo…

Accepted Answer

I am using the below code to convert from duration in `seconds` to the format `HH:MM:SS`.

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

You can easily adjust this to accept input in `minutes` but then your output will be in the format of `HH:MM:00` since you do not have seconds, e.g.:

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