you need to create datepicker of your own or find some library that allowed to strict date and apply date range — Iqbal Rizky, Apr 05 '20 at 21:39

when you describe onPickerListener
something like this

DatePickerDialog.OnDateSetListener d=new DatePickerDialog.OnDateSetListener() {
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        dateAndTime.set(Calendar.YEAR, year);
        dateAndTime.set(Calendar.MONTH, monthOfYear);
        dateAndTime.set(Calendar.DAY_OF_MONTH, dayOfMonth);
        setInitialDateTime();
    }
};

describe and process your special days inside onDateSet
imho

You can use MaterialDateTimeOPicker

Pass values in this list that are the acceptable dates for the picker.


Calendar now = Calendar.getInstance();
DatePickerDialog datePicker = DatePickerDialog.newInstance(
  MainActivity.this,
  now.get(Calendar.YEAR), // Initial year selection
  now.get(Calendar.MONTH), // Initial month selection
  now.get(Calendar.DAY_OF_MONTH) // Inital day selection
);

 datePicker.setSelectableDays(Calendar[] days)

Yesterday, I posted a question asking How can I enable only specific dates in DatePicker Android. Like whenever user click on specific day only those respective dates will available in DatePicker?. I have solved it, which I will share here:

Here are the screenshots that when user click on Monday then DatePicker pops up and enable only Mondays from that day.

code

@Override    
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                    Day day = days.get(position);
                    switch (day.getDay()){
                        case "Monday":
                            appDay = 2;
                            break;
                        case "Tuesday":
                            appDay = 3;
                            break;
                        case "Wednesday":
                            appDay = 4;
                            break;
                        case "Thursday":
                            appDay = 5;
                            break;
                        case "Friday":
                            appDay = 6;
                            break;
                        case "Saturday":
                            appDay = 7;
                            break;
                        case "Sunday":
                            appDay = 1;
                            break;
                        default:
                            appDay = 0;
                            break;
                    }
                    datePickerDialog = DatePickerDialog.newInstance(DayListFragment.this,Year, Month, Day);
                    datePickerDialog.setThemeDark(false);
                    datePickerDialog.setTitle("Select Appointment Date");
                    Calendar calendar1 = Calendar.getInstance();
                    int today = calendar1.get(Calendar.DAY_OF_WEEK);
                    if ( appDay == today)
                    {
                        int update = 0;
                        for (int i = 0; i < calendars.length; i++)
                        {
                            final Calendar calendar2 = Calendar.getInstance();
                            calendar2.get(Calendar.DAY_OF_WEEK);
                            calendar2.add(Calendar.DATE, update);
                            calendars[i] = calendar2;
                            update += 7;
                        }
                    }
                    else if ( appDay > today)
                    {
                        int for1 = appDay - today;
                        for (int i = 0; i < calendars.length; i++)
                        {
                            final Calendar calendar2 = Calendar.getInstance();
                            calendar2.get(Calendar.DAY_OF_WEEK);
                            calendar2.add(Calendar.DATE, for1);
                            calendars[i] = calendar2;
                            for1 += 7;
                        }
                    }
                    else if ( appDay < today)
                    {
                        int for2 = (7-today)+appDay;
                        for (int i = 0; i < calendars.length; i++)
                        {
                            final Calendar calendar2 = Calendar.getInstance();
                            calendar2.get(Calendar.DAY_OF_WEEK);
                            calendar2.add(Calendar.DATE, for2);
                            calendars[i] = calendar2;
                            for2 += 7;
                        }
                    }
                    datePickerDialog.setSelectableDays(calendars);
                    datePickerDialog.show(getFragmentManager(),"DatePickerDialog");
                }

You could have simplified this snippet to ```datePickerDialog.setSelectableDays(calendars)```, the rest of the code doesn't answer the question. The problem is that native ```DatePickerDialog``` doesn't have such method. Probably, you use some library and you should have mentioned this. — Pavlo28, Nov 19 '20 at 10:03
After searching several days, able to find this comment. Helped a lot. If the developer(s) could incorporate examples for each of the feature, it help a lot for novice persons. Thank you. — Sriram Nadiminti, Jun 26 '22 at 06:44
