通过Calendar简单解析Date日期，获取年、月、日、星期的数值

有时候项目中需要用到Date的年、月、日、星期的数值。那么解析方法如下：

/**解析日期，获取年月日星期*/

    private void parseDateToYearMonthDayWeek(Date date){

        //获取默认选中的日期的年月日星期的值，并赋值

        Calendar calendar = Calendar.getInstance();//日历对象

        calendar.setTime(date);//设置当前日期

        String yearStr = calendar.get(Calendar.YEAR)+"";//获取年份

        int month = calendar.get(Calendar.MONTH) + 1;//获取月份

        String monthStr = month < 10 ? "0" + month : month + "";

        int day = calendar.get(Calendar.DATE);//获取日

        String dayStr = day < 10 ? "0" + day : day + "";

        int week = calendar.get(Calendar.DAY_OF_WEEK);

        String weekStr = "";

        /*星期日:Calendar.SUNDAY=1

         *星期一:Calendar.MONDAY=2

         *星期二:Calendar.TUESDAY=3

         *星期三:Calendar.WEDNESDAY=4

         *星期四:Calendar.THURSDAY=5

         *星期五:Calendar.FRIDAY=6

         *星期六:Calendar.SATURDAY=7 */

        switch (week) {

            case 1:

                weekStr = "周日";

                break;

            case 2:

                weekStr = "周一";

                break;

            case 3:

                weekStr = "周二";

                break;

            case 4:

                weekStr = "周三";

                break;

            case 5:

                weekStr = "周四";

                break;

            case 6:

                weekStr = "周五";

                break;

            case 7:

                weekStr = "周六";

                break;

            default:

                break;

        }

        Log.e(TAG, yearStr + "年" + monthStr + "月" + dayStr + "日" + "  " + weekStr);

    }

使用方法：

Date todayDate = Calendar.getInstance().getTime();

parseDateToYearMonthDayWeek(todayDate);
