How do I correctly display the position/duration of a MediaPlayer?


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.

Here is the code I am using:

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

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

Kindly help me out, Swathi Daruri.


Solution

  • 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).

    You'd need to do something like

    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();
    }
    

    And then do something like

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