Is there something like TimeSpan in Android development?

I need to know if there is something like a difference in the development of Android?

There is something like in C #, and I like to use it in two ways:

  • create a time interval, and then add, for example. minutes and then display the entire range
  • create a time interval between two DateTime (which is equivalent for DateTime in android?)

public long addSeconds(long dt,int sec) //method to add seconds in time  
{

    Date Dt = new Date(dt);
    Calendar cal = new GregorianCalendar();

    SimpleDateFormat sdf = new SimpleDateFormat("MM-dd-yyyy HH:mm:ss");
    sdf.setCalendar(cal);
    cal.setTimeInMillis(Dt.getTime());
    cal.add(Calendar.SECOND, sec);
    return cal.getTime().getTime();

}

transfer date and time in seconds, it will return the changed time ...

Unfortunately, there is no class TimeSpanthat is still available in Java, but you can achieve this with a few lines of code.

Calendar startDate = getStartDate();
Calendar endDate = getEndDate();

long totalMillis = endDate.getTimeInMillis() - startDate.getTimeInMillis();
int seconds = (int) (totalMillis / 1000) % 60;
int minutes =  ((int)(totalMillis / 1000) / 60) % 60;
int hours = (int)(totalMillis / 1000) / 3600;

Android has DateUtils, the "formatElapsedTime" method does what you need if you give it the correct input.

You can easily get "TimeSpan" in milliseconds. To convert milliseconds to formatted, you can do a small quick and elegant calculation in your function, for example,

public static String GetFormattedTimeSpan(final long ms) {
    long x = ms / 1000;
    long seconds = x % 60;
    x /= 60;
    long minutes = x % 60;
    x /= 60;
    long hours = x % 24;
    x /= 24;
    long days = x;

    return String.format("%d days %d hours %d minutes %d seconds", days, hours, minutes, seconds);
}

Dates in Java are inconvenient. Take a look at https://github.com/dlew/joda-time-android
