大家好，我有一个DatePickerRange与材料设计，一切都是完美的工作

CalendarConstraints.Builder constraitBuilder = new CalendarConstraints.Builder();
        constraitBuilder.setStart(mesPresente);
        constraitBuilder.setEnd(limitDate);
       // selectedPair = new Pair<>(today,);  Selecionar da por default in DateRangePicker
        //Date Range Picker
        MaterialDatePicker.Builder<Pair<Long, Long>> builder = MaterialDatePicker.Builder.dateRangePicker();
        builder.setTitleText("Seleciona a data");
        //builder.setSelection(selectedPair);
        builder.setCalendarConstraints(constraitBuilder.build()); // Delemita calendario apenas no ano atual
        final MaterialDatePicker materialDatePicker = builder.build();

        txtCalendar.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                materialDatePicker.show(getActivity().getSupportFragmentManager(),"DATE_PICKER");

            }
        });


        materialDatePicker.addOnPositiveButtonClickListener(new MaterialPickerOnPositiveButtonClickListener() {
            @Override
            public void onPositiveButtonClick(Object selection) {
                txtCalendar.setText(materialDatePicker.getHeaderText())
            }
        });

我现在很想数一数，究竟是选择了多少天，即选择了多少天呢？
目前我不知道如何得到这些信息.

感谢Gabriele Mariotti感谢您的帮助，这是非常有价值的，我设法达成了一个解决方案，

materialDatePicker.addOnPositiveButtonClickListener(new MaterialPickerOnPositiveButtonClickListener<Pair<Long, Long>>() {
  @Override public void onPositiveButtonClick(Pair<Long,Long> selection) {
      Long startDate = selection.first;
      Long endDate = selection.second;

      //count days....
       long numDays = endDate - startDate;
       int numDay = (int) TimeUnit.MILLISECONDS.toDays(numDias);

  }
});

更改您的OnPositiveButtonClickListener：

materialDatePicker.addOnPositiveButtonClickListener(new MaterialPickerOnPositiveButtonClickListener<Pair<Long, Long>>() {
  @Override public void onPositiveButtonClick(Pair<Long,Long> selection) {
      Long startDate = selection.first;
      Long endDate = selection.second;

      //count days....

  }
});
