How to format the current date with Suffix to Superscript?

Question

I am using the SimpleDateFormatter

 public static final DateFormat DATE_FORMAT_FULL_FULL_SPACES = 
     new SimpleDateFormat(\"dd MMMM yyyy\", Local         


        

Answer 1

The superscript part isn't the first tricky part here - although it's not clear how you'd want that to be represented anyway (HTML with <sup> tags? something else?)

The first tricky part is knowing how to get the ordinal (st, nd, rd, th) and doing that appropriately for different cultures (which can have very different rules). This isn't something that SimpleDateFormat supports, as far as I'm aware. You should also be aware that different cultures might not use dd MMMM yyyy as their normal full date format - it could look very odd to some people.

I would think very carefully about:

• Which locales you need to support
• Whether you really need the ordinal part
• How you want the superscript to be represented in a string

If you only need to handle English, then the ordinal part isn't too hard (you can probably find examples of a String getOrdinal(int value) method online, or write your own in 5 minutes). If you're also happy to always use a "day first" format, then you'd probably only need to format the month and year in SimpleDateFormat, e.g.

public String formatWithOrdinal(Calendar calendar) {
    DateFormat formatter = new SimpleDateFormat(" MMMM yyyy", Locale.getDefault());
    formatter.setTimeZone(calendar.getTimeZone());
    int day = calendar.get(Calendar.DATE);
    return day + toSuperscript(getOrdinal(day)) + formatter.format(calendar.getTime());
}

Where toSuperscript would use HTML or whatever you need to superscript the value.

In short, you have a lot of separable concerns here - I strongly suggest you separate them, work out your exact requirements, and then implement them as simply as you can.

Create these methods

private String getFormatedDate(){
        String dayNumberSuffix = getDayNumberSuffix(Calendar.getInstance().get(Calendar.DAY_OF_MONTH));
        SimpleDateFormat dateFormat = new SimpleDateFormat(" d'" + dayNumberSuffix + "' MMMM yyyy");
        return dateFormat.format(Calendar.getInstance().getTime());
    }

    private String getDayNumberSuffix(int day) {
        if (day >= 11 && day <= 13) {
            return "<sup>th</sup>";
        }
        switch (day % 10) {
            case 1:
                return "<sup>st</sup>";
            case 2:
                return "<sup>nd</sup>";
            case 3:
                return "<sup>rd</sup>";
            default:
                return "<sup>th</sup>";
        }
    }

How to call?

String str = getFormatedDate();
        txtDate.setText(Html.fromHtml(str));
