Solution

  • Try this ,it is working for all time, only change time_for_night in this format :-

    String startDatetime = "11:00 PM";
            String endDatetime = "07:00 AM";
            String time_for_night = "11:05 PM";
            Integer night_extra_charges=0;
            SimpleDateFormat formatfornightcharges = new SimpleDateFormat("hh:mm aa", Locale.ENGLISH);
            try {
                Date startDate = formatfornightcharges.parse(startDatetime);
                Date selectedTimeforBooking = formatfornightcharges.parse(time_for_night);
                Date endDate = formatfornightcharges.parse(endDatetime);
                if ((selectedTimeforBooking.after(startDate)) || (selectedTimeforBooking.before(endDate))) {
                    Toast.makeText(ScanDocumentsActivity.this, "200", Toast.LENGTH_SHORT).show();
                    night_extra_charges = 200;
                    Log.wtf("night_extra_charges",""+night_extra_charges);
                } else {
                    night_extra_charges = 0;
                    Log.wtf("night_extra_charges",""+night_extra_charges);
                    Toast.makeText(ScanDocumentsActivity.this, "0", Toast.LENGTH_SHORT).show();
                }
            } catch (ParseException e) {
                e.printStackTrace();
            } catch (java.text.ParseException e) {
                e.printStackTrace();
            }
