Convert Minutes to milliseconds Java/android
提问by TheDevMan
I am trying to convert given number of minutes into milliseconds.
我正在尝试将给定的分钟数转换为毫秒。
For eg: 15mins or 20mins or 44mins should be converted to milliseconds programmatically.
例如：15 分钟或 20 分钟或 44 分钟应以编程方式转换为毫秒。
I tried the below:
我尝试了以下方法：
Calendar alarmCalendar = Calendar.getInstance();
alarmCalendar.set(Calendar.MINUTE,15);
long alarmTime = alarmCalendar.getTimeInMillis();
Log.e("Milli", "seconds"+alarmTime);
This doesn't give the right value? What is the best way to convert this?
这没有给出正确的值？转换它的最佳方法是什么？

int minutes = 42;
long millis = minutes * 60 * 1000;

1 minute = 60000 millisecs.
1 分钟 = 60000 毫秒。
int minutes = 1;
long milliseconds = minutes * 60000;

This gives you the time in milli.
这为您提供了以毫为单位的时间。
long currentTime = System.currentTimeMillis()
Handler handler = new Handler();
long waitTime = currentTime + (15*60*1000);
handler.postDelayed(new Runnable() {
public void run() {
// Alert or do something here.
}
}, waitTime);
This piece of code sleeps for 15 minutes and then executes the handler's run method. This way you can raise an alarm etc...
这段代码休眠 15 分钟，然后执行处理程序的 run 方法。这样你就可以发出警报等......

In Java 8+, use java.time.
在 Java 8+ 中，使用java.time.
java.time.Duration.ofMinutes(15).toMillis();
