如何正确显示 MediaPlayer 的位置/持续时间? [英] How do I correctly display the position/duration of a MediaPlayer?

问题描述

嗨我想以简单的日期格式显示玩家位置和玩家持续时间.那是.00:00:01/00:00:06.第一部分是玩家的当前位置，第二部分是持续时间.我使用 SimpleDateFormat 尝试以这种格式显示持续时间和位置，但它显示输出为 05:30:00/05:30:06.

Hi I want to display player position and player duration in simple date format. that is. 00:00:01/00:00:06. The first part is current position of the player and the second part is the duration. I have used SimpleDateFormat to try display the duration and position in this format, but it is showing me the output as 05:30:00/05:30:06.

这是我正在使用的代码:

Here is the code I am using:

time1 = new SimpleDateFormat("HH:mm:ss");
currentTime.setText("" + time1.format(player.getCurrentPosition());

如何正确打印位置和持续时间?(它显示不应该存在的小时/分钟).

How do I print out the position and duration correctly? (It is displaying hours/minutes that should not be there).

请帮帮我，Swathi Daruri.

Kindly help me out, Swathi Daruri.

推荐答案

DateFormat 适用于日期，不适用于时间间隔.因此，如果您获得 1 秒的位置，DateFormat 会将其解释为日期/时间是日历开始后 1 秒(即 1970 年 1 月 1 日).

DateFormat works for dates, not for time intervals. So if you get a position of 1 second, the DateFormat interprets this as meaning that the date/time is 1 second after the beginning the calendar (which is January 1st, 1970).

你需要做类似的事情

private String getTimeString(long millis) {
    StringBuffer buf = new StringBuffer();

    int hours = (int) (millis / (1000 * 60 * 60));
    int minutes = (int) ((millis % (1000 * 60 * 60)) / (1000 * 60));
    int seconds = (int) (((millis % (1000 * 60 * 60)) % (1000 * 60)) / 1000);

    buf
        .append(String.format("%02d", hours))
        .append(":")
        .append(String.format("%02d", minutes))
        .append(":")
        .append(String.format("%02d", seconds));

    return buf.toString();
}

然后做类似的事情

totalTime.setText(getTimeString(duration));
currentTime.setText(getTimeString(position));
