Is there something like TimeSpan in android development?

Question

I need to know if there is something like a timespan in android development?

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

1. generate a timespan and then add e.g. minutes and then display the whole span
2. generate the timespan between two DateTime (what is the equivalent for DateTime in android?)

Answer 1

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();

} 

pass date and time in sec, it will return modified time...

Answer 2

Unfortunately, there's no TimeSpan like class yet natively available in Java, but you can achieve this with 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 method "formatElapsedTime" does what you need if you give it the right input.
