安卓开发音乐软件之歌曲播放进度换算

int currentPosition = mediaPlayer.getCurrentPosition() / 1000; //把播放时长换算成秒

//直接除以60取余就是秒数
int ms = currentPosition % 60;
String m = String.valueOf(ms);
if (ms < 10){
m = "0" + m;
}

//计算出分钟
int mi = currentPosition / 60 % 60;
String mn = String.valueOf(mi);
if (mi < 10){
mn = "0" + mn;
}

String showTime = mn + "." + m;
