Question

我有两个日期，一个是未来日期，另一个是当前日期。我希望得到这两个日期之间的区别我正在使用下面的代码，但输出不是我想通过这个帮助我。我是android编程的新手。

public void getDateDifference(String FutureDate) {
    SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");

    try {

        Date currentDate = dateFormat.parse(FutureDate);
        System.out.println(currentDate);

        Date oldDate = new Date();

        long diff = currentDate.getTime() - oldDate.getTime();
        long seconds = diff / 1000;
        long minutes = seconds / 60;
        long hours = minutes / 60;
        long days = hours / 24;

        counterDaysTV.setText(days + "");
        counterMinsTV.setText(minutes + "");
        counterHoursTV.setText(hours + "");
        counterSecTV.setText(seconds + "");


    } catch (Exception e) {

        e.printStackTrace();
    }

}

我正在使用这种方法找到差异，但它显示为71天是正确但接下来显示1716小时102987分钟和6179267秒我希望它显示像倒计时，请帮助我。

Answer 1

你总是用整个时差计算。

首先必须计算天数，然后计算剩余时间。然后用剩余的分钟等等。

public void getDateDifference(String FutureDate) {

    SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");

    try {
        Date currentDate = dateFormat.parse(FutureDate);
        System.out.println(currentDate);

        Date oldDate = new Date();

        long diff = currentDate.getTime() - oldDate.getTime();

        long days = diff / (24 * 60 * 60 * 1000);
        diff -= days * (24 * 60 * 60 * 1000);

        long hours = diff / (60 * 60 * 1000);
        diff -= hours * (60 * 60 * 1000);

        long minutes = diff / (60 * 1000);
        diff -= minutes * (60 * 1000);

        long seconds = diff / 1000;

        counterDaysTV.setText(days + "");
        counterMinsTV.setText(minutes + "");
        counterHoursTV.setText(hours + "");
        counterSecTV.setText(seconds + "");

    } catch (Exception e) {
        e.printStackTrace();
    }
}

下面的代码可能有效，只是试一试...请注意，这不是我觉得有效的方法......

        long days = diff / (24*60*60*1000);
        long hours=(diff/(60*60*1000))-(days*24);
        long minutes=(diff/(60*1000))-(days*24*60)-(hours*60);
        long seconds=(diff/(1000))-(days*24*60*60)-(hours*60*60)-(minutes*60);

我对davidtrautmann的答案有一些修改，而不是davidtrautmann。用户可以找到更好的方法来获取当前时间和过去日期之间的差异，包括天，小时，小时和秒。用户还可以根据自己的要求进行修改。

public String getDifferentBetweenTwoDates(String pastDate ){//your input date format should be same as your dateformater

    SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    Date inputDate = null;
    try {
        inputDate = format.parse(pastDate); // format.parse("2016-04-04 20:10:10");

    }catch (ParseException e) {
        e.printStackTrace();
    }

    Calendar pastCalendar = Calendar.getInstance();
    if(inputDate!=null){
        pastCalendar.setTime(inputDate);
    }
    long pastDateTimeInMilli = pastCalendar.getTimeInMillis();

    Calendar currentCalendar = Calendar.getInstance();
    long currentDateTimeInMilli = currentCalendar.getTimeInMillis();

    String strDifference="";
    long different = currentDateTimeInMilli - pastDateTimeInMilli;

    long secondsInMilli = 1000;
    long minutesInMilli = secondsInMilli * 60;
    long hoursInMilli = minutesInMilli * 60;
    long daysInMilli = hoursInMilli * 24;

    int elapsedDays = (int)(different / daysInMilli);
    different = different % daysInMilli;

    if(elapsedDays>0){
        strDifference = ""+elapsedDays;
        return strDifference+" days ago";
    }

    int elapsedHours = (int)(different / hoursInMilli);
    different = different % hoursInMilli;
    if(elapsedHours>0){
        strDifference = ""+elapsedHours;
        return strDifference+" hours ago";
    }

    int elapsedMinutes = (int)(different / minutesInMilli);
    different = different % minutesInMilli;
    if(elapsedMinutes>0){
        strDifference = ""+elapsedMinutes;
        return strDifference+" minuts ago";
    }

    int elapsedSeconds = (int)(different / secondsInMilli);
    if(elapsedSeconds>0){
        strDifference = ""+elapsedSeconds;
        return strDifference +"  seconds ago";
    }else{
        return "just now";
    }

}

如何以天数小时和分钟的形式从两个日期中获得差异
