java - 安卓分钟:seconds

Question

我正在寻找一种解决方案来显示 1785.16 string android 设备的分钟:秒持续时间

在 php 中很简单:

<?php
$seconds = '1785.16';
$minutes = floor($seconds/60);
$secondsleft = $seconds%60;
if($minutes<10)
$minutes = "0" . $minutes;
if($secondsleft<10)
 $secondsleft = "0" . $secondsleft;
echo "$minutes:$secondsleft";
?>


This will display: 29:45

Answer 1

所以，我假设您有一个Strings =“1785.16”。然后你可以这样做:

String seconds = "1785.16";
int sec = (int)Float.parseFloat(seconds);
System.out.format("%02d:%02d", sec / 60, sec % 60);
