你们可以这样做。

   c_date=18/05/2012 04:55:00.  and  saved_date=17/05/2012 03:53:00

   long diffInMillisec = c_date.getTime() -saved_date.getTime();
   long diffInSec = TimeUnit.MILLISECONDS.toSeconds(diffInMillisec);
   seconds = diffInSec % 60;
   diffInSec/= 60;
   minutes =diffInSec % 60;
   diffInSec /= 60;
   hours = diffInSec % 24;
   diffInSec /= 24;
   days = diffInSec;`

你可以减去日期和计算差异。 愿:

long difference = calendar.getTimeInMillis()-currentTime;

    long x = difference / 1000;
    seconds = x % 60;
    x /= 60;
    minutes = x % 60;
    x /= 60;
    hours = x % 24;
    x /= 24;
    days = x;

你可以减去你已经计算出的时间。 你们需要时间、休息时间、发言时间等。

I implemented the same thing recently, I used JodaTime. You can download the jar and include it in your Android app from here: http://joda-time.sourceforge.net/

//Create your taget date    
Calendar cal = Calendar.getInstance();
    cal.clear();
    cal.set(Calendar.YEAR, 2012);
    cal.set(Calendar.MONTH, Calendar.JULY);
    cal.set(Calendar.DATE, 15);
    cal.set(Calendar.HOUR_OF_DAY, 8);
    Date startDate = cal.getTime();

//Use JodaTime to calculate difference
    Period period =  getTimePassedSince(startDate);

//Extract values and display
    daysTV.setText("" + Math.abs(period.getDays()));
    hoursTV.setText("" + Math.abs(period.getHours()));
    minsTV.setText("" + Math.abs(period.getMinutes()));
    secsTV.setText("" + Math.abs(period.getSeconds()));

    ...
    public static Period getTimePassedSince(Date initialTimestamp){
            DateTime initDT = new DateTime(initialTimestamp.getTime());
            DateTime now = new DateTime();
            Period p = new Period(initDT, now, PeriodType.dayTime()).normalizedStandard( PeriodType.dayTime());
            return p;
        }

从所有这些答复来看,这是我所要到的。

fun hoursBetween(date: Date): Long = TimeUnit.MILLISECONDS.toHours(date.time - Date().time)
fun minutesBetween(date: Date): Long = TimeUnit.MILLISECONDS.toMinutes(date.time - Date().time) % 60
fun secondsBetween(date: Date): Long = TimeUnit.MILLISECONDS.toSeconds(date.time - Date().time) % 60

希望:

rel=“nofollow”Date。

With getTime() method, you can have the time in miliseconds of the 2 Dates. Then you can create another Date object with the amount of miliseconds results of the subtraction between both Dates. And you ll have the amount of days, hours and minutes since the first Date.
