Good afternoon friends.
What I want to do is get a time range, comparing 2 dates for example:
//Ejemplo simple
String fechaInicial: "03/09/2016 12:00"
String fechaActual: "03/09/2017 12:00"
And what I want to get is for example, this is not accurate Dias: 365, mes(es): 12, Año(s): 1, Hora(s): 8760
It would be great to be able to get the days, for each month.
DateTimeUtils obj = new DateTimeUtils();
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd/M/yyyy
hh:mm:ss");
try {
Date date1 = simpleDateFormat.parse("10/10/2013 11:30:10");
Date date2 = simpleDateFormat.parse("13/10/2013
20:35:55");obj.printDifference(date1, date2);
} catch (ParseException e) {
e.printStackTrace();
}
//1 minute = 60 seconds
//1 hour = 60 x 60 = 3600
//1 day = 3600 x 24 = 86400
public void printDifference(Date startDate, Date endDate) {
//milliseconds
long different = endDate.getTime() - startDate.getTime();
System.out.println("startDate : " + startDate);
System.out.println("endDate : "+ endDate);
System.out.println("different : " + different);
long secondsInMilli = 1000;
long minutesInMilli = secondsInMilli * 60;
long hoursInMilli = minutesInMilli * 60;
long daysInMilli = hoursInMilli * 24;
long elapsedDays = different / daysInMilli;
different = different % daysInMilli;
long elapsedHours = different / hoursInMilli;
different = different % hoursInMilli;
long elapsedMinutes = different / minutesInMilli;
different = different % minutesInMilli;
long elapsedSeconds = different / secondsInMilli;
System.out.printf(
"%d days, %d hours, %d minutes, %d seconds%n",
elapsedDays, elapsedHours, elapsedMinutes, elapsedSeconds);
}
Out put:
startDate : Thu Oct 10 11:30:10 SGT 2013
endDate : Sun Oct 13 20:35:55 SGT 2013
different : 291945000
3 days, 9 hours, 5 minutes, 45 seconds

Remember to have the JodaTime library.

//Para obtener los días de un mes en específico: (en este caso Febrero del 2016 -año bisiesto)
calInicial.set(Calendar.YEAR, 2016); //Hay que indicar el año y el mes
calInicial.set(Calendar.MONTH, 1); //0 = enero, 1 = febrero ...
//calInicial.set(2016,1,1); //Tambien puede ser de esta otra forma(año, mes, día)
int numDias = calInicial.getActualMaximum(Calendar.DATE);
//Lo muestras en TextViews:
tv1.setText(""+difEnMillis);
tv2.setText(String.valueOf(difEnAños));
tv3.setText(""+difEnMeses);
tv4.setText(""+difEnSemanas);
tv5.setText(""+difEnDias);
tv6.setText(""+difEnHoras);
tv7.setText(""+difEnMinutos);
tv8.setText("Febrero 2016 tiene: "+String.valueOf(numDias)+"días");
