Disable specific dates of day in Android date picker

Question

I'm using the datePicker and I can disable last days of today and later days after 30 days by the following code:

DatePickerDialog datePicker = new DatePickerDialog();

             Calendar calender = Calendar.getInstance();
             long today = calender.getTimeInMillis();
             final long oneDay = 24 * 60 * 60 * 1000L;

             Date previousDays = new Date(today - 1000);
             datePicker.setMinDate(DateToCalendar(previousDays));

             Date nextMonth = new Date(today + 30 * oneDay);
             datePicker.setMaxDate(DateToCalendar(nextMonth));

If I want to disable Friday of every month, how can I do this?

Answer 1

You can use this library Material Date Time Picker, here you can set an option to show specific dates, For Example:

datePicker.setSelectableDays(Calendar[] days)

And pass array of Calendar as an parameter which contains all the selectable date.

Answer 2

Use custom DatePickerDialog

add this in build.gradle

compile 'com.wdullaer:materialdatetimepicker:3.5.1'

implement

DatePickerDialog.OnDateSetListener to your class

and import

import com.wdullaer.materialdatetimepicker.date.DatePickerDialog; instead of 'import android.app.DatePickerDialog;'

and add this method

 private void showDatePicker() { 

    Calendar calendar = Calendar.getInstance();

    DatePickerDialog dpd = DatePickerDialog.newInstance(
            this,
            calendar.get(Calendar.YEAR),
            calendar.get(Calendar.MONTH),
            calendar.get(Calendar.DAY_OF_MONTH)
    );
    dpd.show(getActivity().getFragmentManager(), "DatePickerDialog");

    SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy");
    String a = "07-03-2018"; // example

    java.util.Date date = null;

    try {
        date = sdf.parse(a);
    } catch (ParseException e) {
        e.printStackTrace();
    }

    calendar = dateToCalendar(date);
    System.out.println(calendar.getTime());

    List<Calendar> dates = new ArrayList<>();
    dates.add(calendar);
    Calendar[] disabledDays1 = dates.toArray(new Calendar[dates.size()]);
    dpd.setDisabledDays(disabledDays1);

}

    private Calendar dateToCalendar(Date date) {
        Calendar calendar = Calendar.getInstance();
        calendar.setTime(date);
        return calendar;
    }




@Override
public void onDateSet(DatePickerDialog view, int year, int monthOfYear, int dayOfMonth) {

    String date = dayOfMonth+"/"+(monthOfYear+1)+"/"+year;
    textview.setText(date);

}

call showDatePicker().

for multiple days

Change this

     String[] holidays = {"07-03-2018","05-03-2018","10-03-2018"};

    java.util.Date date = null;

    for (int i = 0;i < holidays.length; i++) {

        try {
            date = sdf.parse(holidays[i]);
        } catch (ParseException e) {
            e.printStackTrace();
        }

        calendar = dateToCalendar(date);
        System.out.println(calendar.getTime());

        List<Calendar> dates = new ArrayList<>();
        dates.add(calendar);
        Calendar[] disabledDays1 = dates.toArray(new Calendar[dates.size()]);
        dpd.setDisabledDays(disabledDays1);
    }

Answer 3

That is not possible with the android datepicker and you need to create a custom picker for yourself. See MaterialDateTimePicker

To disable Sundays you have to pass the array like this

      GregorianCalendar g1=new GregorianCalendar();
      g1.add(Calendar.DATE, 1);
      GregorianCalendar gc = new GregorianCalendar();
      gc.add(Calendar.DAY_OF_MONTH, 30);
       List<Calendar> dayslist= new LinkedList<Calendar>();
Calendar[] daysArray;
Calendar cAux = Calendar.getInstance();
while ( cAux.getTimeInMillis() <= gc.getTimeInMillis()) {
    if (cAux.get(Calendar.DAY_OF_WEEK) != 1) {
        Calendar c = Calendar.getInstance();
        c.setTimeInMillis(cAux.getTimeInMillis());
        dayslist.add(c);
    }
    cAux.setTimeInMillis(cAux.getTimeInMillis() + (24*60*60*1000));
}
daysArray = new Calendar[dayslist.size()];
for (int i = 0; i<daysArray.length;i++)
{
    daysArray[i]=dayslist.get(i);
}
datePickerDialog.setSelectableDays(daysArray);
