Answer 1

public void showDatePicker() {

        final Calendar c = Calendar.getInstance();
        int year = c.get(Calendar.YEAR);
        int month = c.get(Calendar.MONTH);
        int day = c.get(Calendar.DAY_OF_MONTH);

        DatePickerDialog datePicker = new DatePickerDialog(getActivity(), (view, year1, month1, day1) -> {
            Calendar c1 = Calendar.getInstance();
            c1.set(year1, month1, day1);
            Date date = c1.getTime();
            SimpleDateFormat formatter = new SimpleDateFormat("dd MMMM yyyy");
            String d = formatter.format(date);
//            btnDatePicker.setText(d);
//            selectedDate = d;
        }, year, month, day) {
            @Override
            public void onClick(@NonNull DialogInterface dialog, int which) {
                super.onClick(dialog, which);
                if (which == DialogInterface.BUTTON_POSITIVE) {
                } else if (which == DialogInterface.BUTTON_POSITIVE) {

                }
            }
        };

        datePicker.getDatePicker().setMinDate(System.currentTimeMillis());
        datePicker.show();
    }
