public static String convertToStr(int progressPosition){
//先求出剩余的余数的毫
int remain=progressPosition%1000;
//求出整数的秒数（可能大于60秒，如果大于60秒则要转换为分钟
int seconds=progressPosition/1000;
int minutes=seconds/60;
//求余数求出剩余的秒数
int remainSecond=seconds%60;
String millSeconds=remain+"";
if(remain<10){
millSeconds="00"+millSeconds;
}else if(remain<100){
millSeconds="0"+millSeconds;
}
String second=remainSecond+"";
if(remainSecond<10){
second="0"+second;
}
String minute=minutes+"";
if(minutes<10){
minute="0"+minute;
}
return "00:"+minute+":"+second+"."+millSeconds;
}
}
ok,一些基本的功能类就这些了。
