如何只用月份和年份字段显示android的日期选择器？

DatePickerDialog datePickerDialog = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
    @Override
    public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
        // 处理日期选择事件
    }
}, initialYear, initialMonth, initialDay);

datePickerDialog.getDatePicker().setCalendarViewShown(false);
datePickerDialog.getDatePicker().setSpinnersShown(true);
datePickerDialog.getDatePicker().setDatePickerMode(DatePickerDialog.MODE_SPINNER);

datePickerDialog.show();
