如何获得昨天约会

Question

我希望昨天的日期或日期不是今天而是过去。我正在使用此代码 -

Calendar calendarMessage = Calendar.getInstance();
        Calendar calendarToday = Calendar.getInstance();
        calendarMessage.setTime(date);
        return calendarMessage.get(Calendar.YEAR) == calendarToday.get(Calendar.YEAR) &&
                calendarMessage.get(Calendar.DAY_OF_YEAR) == calendarToday.get(Calendar.DAY_OF_YEAR);

你能帮帮我吗？

尝试这种方式..

public static String getYesterdayDate() {

    SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
    Calendar cal = Calendar.getInstance();
    cal.add(Calendar.DATE, -1);
    return dateFormat.format(cal.getTime());
}
