i am creating a method that calculate the difference between 2 date (END DATE _ CURRENT DATE). i want to display the date format in months , days , hours, minutes, seconds
like this format : 2 months.3 days. 8 hours. 12 min. 32 second
can anyone help me ??? i will appreciate that.
public void getDiffDate() {
String dateStop = "12.6.2014";
long now = System.currentTimeMillis();
SimpleDateFormat format = new SimpleDateFormat("dd.MM.yyyy");
Date d1 = null;
Date d2 = null;
try {
d1 = new Date(now);
d2 = format.parse(dateStop);
} catch (ParseException e) {
e.printStackTrace();
}
long difference = d2.getTime() - d1.getTime();
long differenceBack = difference;
differenceBack = difference / 1000;
int secs = (int) (differenceBack % 60);
differenceBack /= 60;
int mins = (int) (differenceBack % 60);
differenceBack /= 60;
int hours = (int) (differenceBack % 24);
TextView txtDate = (TextView) findViewById(R.id.txtDifDate);
String resultDate = hours + "H" + " :" + mins + "M" + " :" + secs + "S";
txtDate.setText(resultDate);
}
actually i am getting the result but it is not correct so also i need to fix this error.
Try this:
String dateStart = "01/14/2012 09:29:58";
String dateStop = "01/15/2012 10:31:48";
//HH converts hour in 24 hours format (0-23), day calculation
SimpleDateFormat format = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");
Date d1 = null;
Date d2 = null;
try {
d1 = format.parse(dateStart);
d2 = format.parse(dateStop);
//in milliseconds
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);
System.out.print(diffDays + " days, ");
System.out.print(diffHours + " hours, ");
System.out.print(diffMinutes + " minutes, ");
System.out.print(diffSeconds + " seconds.");
} catch (Exception e) {
e.printStackTrace();
}
//EDIT
Personally I would recommand you Joda Time. Example of Joda Time:
String dateStart = "01/14/2012 09:29:58";
String dateStop = "01/15/2012 10:31:48";
SimpleDateFormat format = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");
Date d1 = null;
Date d2 = null;
try {
d1 = format.parse(dateStart);
d2 = format.parse(dateStop);
DateTime dt1 = new DateTime(d1);
DateTime dt2 = new DateTime(d2);
System.out.print(Days.daysBetween(dt1, dt2).getDays() + " days, ");
System.out.print(Hours.hoursBetween(dt1, dt2).getHours() % 24 + " hours, ");
System.out.print(Minutes.minutesBetween(dt1, dt2).getMinutes() % 60 + " minutes, ");
System.out.print(Seconds.secondsBetween(dt1, dt2).getSeconds() % 60 + " seconds.");
} catch (Exception e) {
e.printStackTrace();
}
First, remove: long differenceBack = difference;
long differenceBack = difference;
differenceBack = difference / 1000;
Should be:
long differenceBack = difference / 1000;
First you need hours, to do this:
int hours = differenceBack/(60*60);
Than you have the remaining seconds:
int remaining = differenceBack%(60*60)
than again check how many minutes you have in the remaining seconds:
int minutes = remaining/60;
check how many seconds you have left:
int seconds = remaining%60;
You began right, by converting milliseconds to seconds. 1 minute = 60 seconds, 1 hour = 60 minutes, or 60*60 seconds. Good luck.
