我用这种方法来计算进度’

public static 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();

}

注意：mPlayer.getCurrentPosition()不准确.报告了一些错误.我有一个问题,即当前位置高于totalDuration.
