how to convert date format in android

To get AM PM and 12 hour date format use hh:mm:ss a as string formatter WHERE hh is for 12 hour format and a is for AM PM format.

Note: HH is for 24 hour and hh is for 12 hour date format

SimpleDateFormat formatter = new SimpleDateFormat("mm/dd/yyyy hh:mm:ss a");
            String newFormat = formatter.format(testDate);

Example

String date = "2011/11/12 16:05:06";
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy/mm/dd HH:MM:SS");
        Date testDate = null;
        try {
            testDate = sdf.parse(date);
        }catch(Exception ex){
            ex.printStackTrace();
        }
        SimpleDateFormat formatter = new SimpleDateFormat("mm/dd/yyyy hh:mm:ss a");
        String newFormat = formatter.format(testDate);
        System.out.println(".....Date..."+newFormat);
