There is no method that does. but you can do it with the Calander class the trick is created two instances of calander for the start date and another for the end date, with a while loop you can check if the start date is before the end date by adding a day to the start date each loop iteration.

here is an example how to do it for me I save the dates as a long :

 ArrayList<Long> dates = new ArrayList<>(); // the list to store all the dates 
 MaterialDatePicker.Builder<Pair<Long, Long>> builder = MaterialDatePicker.Builder.dateRangePicker();
 builder.setTitleText("Select rang");
 MaterialDatePicker<Pair<Long, Long>> materialDatePicker = builder.build();
 materialDatePicker.show(getSupportFragmentManager(), "Test");
 materialDatePicker.addOnPositiveButtonClickListener(new MaterialPickerOnPositiveButtonClickListener<Pair<Long, Long>>() {
            @Override
            public void onPositiveButtonClick(Pair<Long, Long> selection) {
                if (selection.first != null && selection.second != null) {
                    // start date
                    Calendar start = Calendar.getInstance();
                    start.setTimeInMillis(selection.first);
                    // end date 
                    Calendar end = Calendar.getInstance();
                    end.setTimeInMillis(selection.second);
                    
                    while (start.before(end)) {
                        start.add(Calendar.DAY_OF_MONTH, 1); // add one day 
                        Log.d(TAG, "onPositiveButtonClick: " + start.get(Calendar.DAY_OF_MONTH));// show all the day between end and start  
                        dates.add(start.getTimeInMillis());
                    }
                }
            }
        });
