从周数 & 获取周开始和结束日期安卓年 [英] get week start and end date from week number & year in android

问题描述

我希望得到开始日期 &一周的结束日期，用于传递给方法的周数.例如，如果我将周数传递为 51 并将年份传递为 2011，它应该将开始日期返回为 18 Dec 2011 并且结束日期为 2011 年 12 月 24 日

I wish to get the start date & end date of the week, for a week number passed in to the method. For example, if i pass the week number as 51 and the year as 2011, it should return me start date as 18 Dec 2011 and the end date as 24 Dec 2011

有什么方法可以帮助我实现这一目标吗?

Are there any methods that will help me achieve this?

推荐答案

您可以使用以下方法获取一周的第一个日期和结束日期

You can use the following method to get first date and end date of a week

 void getStartEndOFWeek(int enterWeek, int enterYear){
//enterWeek is week number
//enterYear is year
        Calendar calendar = Calendar.getInstance();
        calendar.clear();
        calendar.set(Calendar.WEEK_OF_YEAR, enterWeek);
        calendar.set(Calendar.YEAR, enterYear);

        SimpleDateFormat formatter = new SimpleDateFormat("ddMMM yyyy"); // PST`
        Date startDate = calendar.getTime();
        String startDateInStr = formatter.format(startDate);
        System.out.println("...date..."+startDateInStr);

        calendar.add(Calendar.DATE, 6);
        Date enddate = calendar.getTime();
        String endDaString = formatter.format(enddate);
        System.out.println("...date..."+endDaString);
    }
