                        dateTime.set(year, monthOfYear, dayOfMonth);
                        editDate.setText(dateFormatter
                                .format(dateTime.getTime()));
                    }
                }, dateTime.get(Calendar.YEAR),
                   dateTime.get(Calendar.MONTH),

            }
            return null;
     }

You have to use setMinDate for minimum date and you can also use setMaxDate if you want to set maximum date.

Here is sample code for SetMinDate for DatePickerDialog.

@Override
protected Dialog onCreateDialog(int id) {
        switch (id) {
        case DIALOG_DATE:

            DatePickerDialog mDatePickerDialog = new DatePickerDialog(this, new OnDateSetListener() {

                @Override
                public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                    dateTime.set(year, monthOfYear, dayOfMonth);
                    editDate.setText(dateFormatter.format(dateTime.getTime()));
                }
            }, dateTime.get(Calendar.YEAR), dateTime.get(Calendar.MONTH), dateTime.get(Calendar.DAY_OF_MONTH));
            Calendar mCalendarMinimum = Calendar.getInstance();
            mCalendarMinimum.add(Calendar.HOUR, -1);
            mDatePickerDialog.getDatePicker().setMinDate(mCalendarMinimum.getTimeInMillis());
            return mDatePickerDialog;
        }
        return null;
    }

You can use setMinDate (long minDate) to achieve your goal. Doc says:

Sets the minimal date supported by this NumberPicker in milliseconds since January 1, 1970 00:00:00 in getDefault() time zone.
