如何在Android Studio中的自定义数组列表中对日期进行排序？

您可以使用以下方法按日期对列表进行排序。

 Collections.sort(list, (item1, item2) -> {
            Date date1 = stringToDate(item1.getDate());
            Date date2 = stringToDate(item2.getDate());

            if (date1 != null && date2 != null) {
                boolean b1;
                boolean b2;
                if (isAscending) {
                    b1 = date2.after(date1);
                    b2 = date2.before(date1);
                }else {
                    b1 = date1.after(date2);
                    b2 = date1.before(date2);
                }

                if (b1 != b2) {
                    if (b1) {
                        return -1;
                    }
                    if (!b1) {
                        return 1;
                    }
                }
            }
            return 0;
        });

public static Date stringToDate(String strDate) {
        if (strDate == null)
            return null;

        // change the date format whatever you have used in your model class.
        SimpleDateFormat format = new SimpleDateFormat("MMM dd, yyyy hh:mm:ss a", Locale.US);
        Date date = null;
        try {
            date = format.parse(strDate);
            System.out.println(date);
        } catch (ParseException e) {
            e.printStackTrace();
        }
        return date;
    }
