CountDown Timer - How to display the year, months, weeks, and

In my program, I have to show CountDown Timer, and for this I wrote a code that allows me to get days, hours, minutes and seconds, but I don’t understand how to calculate the year, months and weeks.

However, I get the following:

days:384 hours:6 minutes:27 seconds:25

but I need it:

 year:1 months:2 weeks:5 days:125 hours:6 minutes:27 seconds:25

Check out my code below:

  public class MainActivity extends Activity { String time1="31-08-2015 12:01:00"; TextView tv; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.fragment_main); tv=(TextView)findViewById(R.id.textView1); final Handler handler = new Handler(); handler.postDelayed(new Runnable() { @Override public void run() { Calendar start = Calendar.getInstance(); String time = "dd-MM-yyyy hh:mm:ss"; // 12:00 String dateStart =(String) DateFormat.format(time, start); String dateStop = time1; SimpleDateFormat format = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss"); // Custom date format java.util.Date d1=null; java.util.Date d2=null; try { d1 = format.parse(dateStart); d2 = format.parse(dateStop); } catch (java.text.ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } long diff = d2.getTime() - d1.getTime(); long diffdays =(diff/ (1000*60*60*24)); long diffHours = ((diff - (1000*60*60*24*diffdays)) / (1000*60*60)); long diffMinutes = (diff - (1000*60*60*24*diffdays) - (1000*60*60*diffHours)) / (1000*60); long diffSeconds =(diff - (1000*60*60*24*diffdays) - (1000*60*60*diffHours) -(1000*60*diffMinutes))/ (1000); String out= "days:"+diffdays+ "hours:"+diffHours+ "Minutes:"+diffMinutes+ "seconds:"+diffSeconds; tv.setText(out); handler.postDelayed(this, 1000); } }, 1000); } }

I have this code that works for me and is simpler:

 public static String dhmsDifference(Date d1, Date d2) { long diff = d2.getTime() - d1.getTime(); long diffSeconds = diff / 1000 % 60; long diffMinutes = diff / (60 * 1000) % 60; long diffHours = diff / (60 * 60 * 1000) % 24; long diffDays = diff / (24 * 60 * 60 * 1000); String difference=Long.toString(diffDays)+":"+String.format("%02d", diffHours)+":"+String.format("%02d", diffMinutes)+":"+String.format("%02d", diffSeconds); return difference; }

It returns a string, but you can easily adapt it to your code, I think.

For a month and years, I used a calendar (added to my code):

 Calendar cal1 = Calendar.getInstance(); Calendar cal2 = Calendar.getInstance(); cal1.setTime(d1); cal2.setTime(d2); long months = cal2.get(Calendar.MONTH)-cal1.get(Calendar.MONTH); long years = cal2.get(Calendar.YEAR)-cal1.get(Calendar.YEAR); long weeks = cal2.get(Calendar.WEEK_OF_YEAR)-cal1.get(Calendar.WEEK_OF_YEAR);

You will need to add magic if the year changes, but this is an idea.

EDIT: Does some tests with this more complete code, please:

 public static String ymwdhmsDifference(Date d1, Date d2) { long diff = d2.getTime() - d1.getTime(); long diffSeconds = diff / 1000 % 60; long diffMinutes = diff / (60 * 1000) % 60; long diffHours = diff / (60 * 60 * 1000) % 24; long totalDiffDays = diff / (24 * 60 * 60 * 1000); long diffDays = totalDiffDays % 7; long diffWeeks = totalDiffDays/7; // Full weeks are simply days / 7. diffDays = diffDays % 7; // now we get the remaining days. Calendar cal1 = Calendar.getInstance(); Calendar cal2 = Calendar.getInstance(); cal1.setTime(d1); cal2.setTime(d2); long totalDiffYears = cal2.get(Calendar.YEAR)-cal1.get(Calendar.YEAR); long totalDiffMonths = Math.max(totalDiffYears*12+cal2.get(Calendar.MONTH)-cal1.get(Calendar.MONTH)-1,0); long diffYears = totalDiffMonths / 12; // remaining full months long diffMonths = totalDiffMonths % 12; // now we have to count how many weeks those full months represent, to substract them from the number of weeks... Calendar cal3 = Calendar.getInstance(); cal3.setTime(d1); int month = cal1.get(Calendar.MONTH)+1, year = cal1.get(Calendar.YEAR), monthDays=0; for (int m=0;m<totalDiffMonths;m++) { cal3.set(Calendar.MONTH, month++); monthDays+=cal3.getActualMaximum(Calendar.DAY_OF_MONTH); if (month>=12) { month = 0; year++; cal3.set(Calendar.YEAR, year); } } diffWeeks-=monthDays/7; // Note that the number of weeks can be greater than 4 because they are part of non full months. String difference="Y: "+Long.toString(diffYears)+" M: "+Long.toString(diffMonths)+" W: "+Long.toString(diffWeeks)+" D: "+Long.toString(diffDays)+" H: "+String.format("%02d", diffHours)+" M: "+String.format("%02d", diffMinutes)+" S: "+String.format("%02d", diffSeconds); return difference; }

Or you can just use Joda-Time to do it

 Interval interval = new Interval(startDate.getTime(), endDate.getTime()); Period period = interval.toPeriod(); String strDiff = "Year: " + period.getYears() + "/ Month: " + period.getMonths() + "/ Days: " + period.getDays() + "/ Hours: " + period.getHours() + "/ Minutes: " + period.getMinutes() + "/ Seconds: " + period.getSeconds();

Hope this helps:

 @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_count_down); final TextView time = (TextView)findViewById(R.id.txtCountDown); final GregorianCalendar currentTime=new GregorianCalendar (2014,9,1,9,16,0); GregorianCalendar targetTime=new GregorianCalendar (2016,5,1,11,2,0); long difference = targetTime.getTimeInMillis() - currentTime.getTimeInMillis(); new CountDownTimer(difference,1000) { @Override public void onTick(long arg0) { Calendar countdownDuration = Calendar.getInstance(); countdownDuration.setTimeInMillis(currentTime.getTimeInMillis() + arg0); int year = countdownDuration.get(Calendar.YEAR)-currentTime.get(Calendar.YEAR); int month = countdownDuration.get(Calendar.MONTH); int day = countdownDuration.get(Calendar.DAY_OF_MONTH)-1; int hour = countdownDuration.get(Calendar.HOUR); int minute = countdownDuration.get(Calendar.MINUTE); int sec = countdownDuration.get(Calendar.SECOND); time.setText("Years: " + year + "\nMonth:" + month + "\nDays:" + day +"\nHour:" + hour + "\nMinute" + minute + "\nSecond:" + sec); } @Override public void onFinish() { // TODO Auto-generated method stub } }.start(); }
