change your seek bar value from 1-24 to 1-12 and add some widget for AM and PM — N J, Sep 03 '15 at 08:39
Thank you ...it shows 12 hours format...how to define am and pm in time — Sathya, Sep 03 '15 at 08:50
you can put `ToggleButon` or `RadioButton` for selecting AM or PM — N J, Sep 03 '15 at 08:51

Try this

TimeZone utc = TimeZone.getTimeZone("etc/UTC");
DateFormat inputFormat = new SimpleDateFormat("dd MMM, yyyy HH:mm",
                                              Locale.US);
inputFormat.setTimeZone(utc);
DateFormat outputFormat = new SimpleDateFormat("dd MMM, yyyy hh:mm aa",
                                              Locale.US);
outputFormat.setTimeZone(utc);

Date date = inputFormat.parse(input);
String output = outputFormat.format(date);

If the progresValue variable is integer in the range of 1-24 representing the hour part of time...this would do:

final String time;
if(progressValue > 12){
    time = string.format("%d:00 %s", progressValue - 12, "PM");
}
else if(progressValue == 12){
    time = "12:00 PM";
}
else{
    time = string.format("%d:00 %s", progressValue , "AM");
}
