How to add an additional 1 hour in the time selection dialog box. for example :: If the current hour is 4.00 Pm, then I want to show 17.00 in Time Picker.

                mHour = c.get(Calendar.HOUR_OF_DAY);
                mMinute = c.get(Calendar.MINUTE);

                // Launch Time Picker Dialog
                timePickerDialog = new TimePickerDialog(CheckOut.this,
                        new TimePickerDialog.OnTimeSetListener() {
                            @Override
                            public void onTimeSet(TimePicker view, int hourOfDay,

Answer 1

You need to maintain consistency. If you get HOUR_OF_DAY then you need to set the same

Option 1 : using HOUR_OF_DAY

final Calendar c = Calendar.getInstance();
            c.add(Calendar.HOUR_OF_DAY,1);
            mHour = c.get(Calendar.HOUR_OF_DAY);
            mMinute = c.get(Calendar.MINUTE);

            // Launch Time Picker Dialog
            timePickerDialog = new TimePickerDialog(CheckOut.this,
                    new TimePickerDialog.OnTimeSetListener() {
                        @Override
                        public void onTimeSet(TimePicker view, int hourOfDay,
                                              int minute) {

                            tvTimeSelect.setText("Delivery Time : "+hourOfDay + ":" + minute);
                            timePickerDialog.dismiss();
                        }
                    }, mHour, mMinute, false);
            timePickerDialog.show();

Option 2 : using HOUR

final Calendar c = Calendar.getInstance();
            c.add(Calendar.HOUR,1);
            mHour = c.get(Calendar.HOUR);
            mMinute = c.get(Calendar.MINUTE);

            // Launch Time Picker Dialog
            timePickerDialog = new TimePickerDialog(CheckOut.this,
                    new TimePickerDialog.OnTimeSetListener() {
                        @Override
                        public void onTimeSet(TimePicker view, int hourOfDay,
                                              int minute) {

                            tvTimeSelect.setText("Delivery Time : "+hourOfDay + ":" + minute);
                            timePickerDialog.dismiss();
                        }
                    }, mHour, mMinute, false);
            timePickerDialog.show();

Answer 2

Try c.add(Calendar.HOUR_OF_DAY,1);insteadc.add(Calendar.HOUR,1);
