格式化秒和分钟 [英] Formatting seconds and minutes

问题描述

我需要从毫秒格式化秒和分钟。我正在使用countdownTimer。有没有人有sugestions？我看着乔达的时间。但所有我需要的是格式，所以我有1:05而不是1：5。谢谢

  private void walk（）{
 New CountDownTimer（15000，1000）{
 @Override 
 public void onFinish（）{
 lapCounter ++; 
 lapNumber.setText（Lap Number：+ lapCounter）; 
 run（）; 
 
 $ b @Override 
 public void onTick（long millisUntilFinished）{
 text.setText（剩余时间：+ millisUntilFinished / 1000）; 
} 
} .start（）; 
 
  

解决方案

您可以使用标准的日期格式化类，但这可能有点重量级。我只是使用String.format方法。例如：

  int minutes = time /（60 * 1000）; 
 int seconds =（time / 1000）％60; 
 String str = String.format（％d：％02d，分钟，秒）; 
  

I need to format seconds and minutes from milliseconds. I am using countdownTimer. does anyone have sugestions? I looked at joda time. But all i need is a format so i have 1:05 and not 1:5. thanks

private void walk() {
    new CountDownTimer(15000, 1000) {
        @Override
        public void onFinish() {
            lapCounter++;
            lapNumber.setText("Lap Number: " + lapCounter);
            run();
        }

        @Override
        public void onTick(long millisUntilFinished) {
            text.setText("Time left:" + millisUntilFinished/1000);
        }
    }.start();
}

解决方案

You could do it using the standard Date formatting classes, but that might be a bit heavy-weight. I would just use the String.format method. For example:

int minutes = time / (60 * 1000);
int seconds = (time / 1000) % 60;
String str = String.format("%d:%02d", minutes, seconds);
