generate dates between two date in Android

Question

How to get all dates between two dates in Android.

For example. I have two Strings.

String first=\"2012-07-15\";  
String second=\"2012-07-21\"; 
         


        

Answer 1

it is better not to use any hardcoded values in date calculations. we can rely on java Calendar class methods to do this task

see the code

private static List getDates(String dateString1, String dateString2)
{
    ArrayList dates = new ArrayList();
    DateFormat df1 = new SimpleDateFormat("yyyy-MM-dd");

    Date date1 = null;
    Date date2 = null;

    try {
        date1 = df1 .parse(dateString1);
        date2 = df1 .parse(dateString2);
    } catch (ParseException e) {
        e.printStackTrace();
    }

    Calendar cal1 = Calendar.getInstance();
    cal1.setTime(date1);


    Calendar cal2 = Calendar.getInstance();
    cal2.setTime(date2);

    while(!cal1.after(cal2))
    {
        dates.add(cal1.getTime());
        cal1.add(Calendar.DATE, 1);
    }
    return dates;
}

and use it as below

    List dates = getDates("2012-02-01", "2012-03-01");
    for(Date date:dates)
        System.out.println(date);
