我加上
String endTime = (String) list.get(0).get("endTime");
        long now= Long.parseLong(nowTime);
        long end = Long.parseLong(endTime);
        long f = now-end;
        if(f>3){
            e.put("flag",new String("过期"));
            list.add(e);
        } 
        这几行代码之后报错，我要endtime和现在时间是不是差3天。

字符串 "2016-03-15 10:18" 直接转时间戳吗？

传统：先转成date，然后getTime，时间戳层面上进行比较
新：

    SimpleDateFormat toFormate = new SimpleDateFormat("yyyy-MM-dd ");
    Calendar cal = Calendar.getInstance();
    String now = toFormate.format(cal.getTime());
    cal.add(Calendar.DATE, -1);
    String yesterday = toFormate.format(cal.getTime());
    cal.add(Calendar.DATE, -7);
    String weeked = toFormate.format(cal.getTime());
