Body
copied!<p>I created an audio player, and I have a class in my project for working with duration. How can one make sure that totalDuration has counted in the opposite direction? </p> <pre><code>public class Utilities { public String milliSecondsToTimer(long milliseconds){ String finalTimerString = ""; String secondsString = ""; // Convert total duration into time int hours = (int)( milliseconds / (1000*60*60)); int minutes = (int)(milliseconds % (1000*60*60)) / (1000*60); int seconds = (int) ((milliseconds % (1000*60*60)) % (1000*60) / 1000); // Add hours if there if(hours > 0){ finalTimerString = hours + ":"; } // Prepending 0 to seconds if it is one digit if(seconds < 10){ secondsString = "0" + seconds; }else{ secondsString = "" + seconds;} finalTimerString = finalTimerString + minutes + ":" + secondsString; // return timer string return finalTimerString; } public int getProgressPercentage(long currentDuration, long totalDuration){ Double percentage = (double) 0; long currentSeconds = (int) (currentDuration / 1000); long totalSeconds = (int) (totalDuration / 1000); // calculating percentage percentage =((((double)currentSeconds)/totalSeconds)*100); // return percentage return percentage.intValue(); } public int progressToTimer(int progress, int totalDuration) { int currentDuration = 0; totalDuration = (int) (totalDuration / 1000); currentDuration = (int) ((((double)progress) / 100) * totalDuration); // return current duration in milliseconds return currentDuration * 1000; } } </code></pre>
