period.getDays()在android中每次返回0

LocalDate startDate = LocalDate.of(2023, 1, 1);
LocalDate endDate = LocalDate.of(2023, 1, 10);
Period period = Period.between(startDate, endDate);

int days = period.getDays(); // 这将返回0，因为没有完整的月份或年份差异

import java.time.LocalDate;
import java.time.temporal.ChronoUnit;

LocalDate startDate = LocalDate.of(2023, 1, 1);
LocalDate endDate = LocalDate.of(2023, 1, 10);

long daysBetween = ChronoUnit.DAYS.between(startDate, endDate);
System.out.println("Days between: " + daysBetween); // 这将返回9
