I am taking an example of date given below and print two different format of dates according to your requirements.
String date="01/10/2014 05:54:00 PM";
SimpleDateFormat simpleDateFormat=new SimpleDateFormat("dd/MM/yyyy hh:mm:ss aa",Locale.getDefault());
try {
Log.i("",""+new SimpleDateFormat("ddMMyyyyHHmmss",Locale.getDefault()).format(simpleDateFormat.parse(date)));
Log.i("",""+new SimpleDateFormat("dd/MM/yyyy HH:mm:ss",Locale.getDefault()).format(simpleDateFormat.parse(date)));
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
If you still have any query, Please respond. Thanks.
