java - 从 calendar.getInstance 获取错误的日期

Question

今天的日期: 2016 年 4 月 21 日星期四

Calendar calendar = Calendar.getInstance();
int year = calendar.get(Calendar.YEAR);
int month = calendar.get(Calendar.MONTH);
int day = calendar.get(Calendar.DAY_OF_MONTH);
int weekOfDay = calendar.get(Calendar.DAY_OF_WEEK_IN_MONTH);

Utilities.trace("MainActivity, year = " + year + " month = " + month + " day = " + weekOfDay);

但结果我得到day = 3。我不明白为什么..

Answer 1

您正在打印 weekOfDay 而不是 day

Utilities.trace("MainActivity, year = " + year + " month = " + month + " day = " + weekOfDay);

更改为

Utilities.trace("MainActivity, year = " + year + " month = " + month + " day = " + day);

由于 WeekOfDay 将从 0 开始，因此周四显示为 3
