Basically I am making an appointment application. So I am showing days in a list, when user select any day then the datepicker pops up and shows only respective day date enabled 3,4 weeks. For example, if I select Monday then all the Mondays of this month enabled. 7, 14, 21, 28

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;
