java - 安卓分钟：秒

Question

我正在寻找一种解决方案来显示 minutes:seconds持续时间1785.16 string android device

在 php 中它很简单：

<?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，我假设你有一个String seconds = "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);

Answer 2

另一种方法是这样的：

float seconds = Float.parseFloat("1785.16");
Date date = new Date((long)(seconds * 1000));
SimpleDateFormat formater = new SimpleDateFormat("mm:ss");
String formatedDate = formater.format(date);
android.util.Log.d("This will display:", formatedDate);

它对对象更友好^^而且您可以轻松更改格式！
