Question

In my application i have 2 field, 1 is date and another is recc(is an integer) in database table.

Now i will explain my requirement:

Consider suppose user enters today’s date(26-07-2012) and recc as 10.It means that starting from today’s date to that +10 date.I got that 10th date from today’s date.But what i want is 10th day from today’s date means it will surely go to next month also (26-07-2012—-5-08-2012),but i have to know the count of date which falls in this particular month,(i.e)between 26-07-2012—-5-08-2012 how many days it will fall within this month.I think i have explained my problem clearly,if not i am ready to give more explanation.Thanks in advance.

Date value:

 EditText date=(EditText)findViewById(R.id.startdateexp);       
             String startdate=date.getText().toString();

Answer 1

you can do this by following way:
1. Get date from Database.

Now get day of month from the date by following method:

DateFormat iso8601Format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    try {
    date = iso8601Format.parse(dateTime);
    } catch (ParseException e) {
    Log.e(TAG, "Parsing ISO8601 datetime failed", e);
    }
    Calendar cal=Calendar.getInstance();
    cal.setTime(date);
    int currentDay= cal.get(Calendar.DAY_OF_MONTH);

calculate Last day of month by:

    int lastDay = cal.getActualMaximum(Calendar.DAY_OF_MONTH);
