Get current time and date on Android

如何在Android应用程序中获取当前时间和日期？

---

You could use:

import java.util.Calendar

Date currentTime = Calendar.getInstance().getTime();

There are plenty of constants in Calendar for everything you need.

Edit:
Check Calendar class documentation

---

You can (but no longer should - see below!) use android.text.format.Time:

Time now = new Time();
now.setToNow();

From the reference linked above:

The Time class is a faster replacement for the java.util.Calendar and java.util.GregorianCalendar classes. An instance of the Time class represents a moment in time, specified with second precision.

---

NOTE 1: It's been several years since I wrote this answer, and it is about an old, Android-specific and now deprecated class. Google now says that "[t]his class has a number of issues and it is recommended that GregorianCalendar is used instead".

---

NOTE 2: Even though the Time class has a toMillis(ignoreDaylightSavings) method, this is merely a convenience to pass to methods that expect time in milliseconds. The time value is only precise to one second ; the milliseconds portion is always 000 . If in a loop you do

Time time = new Time();   time.setToNow();
Log.d("TIME TEST", Long.toString(time.toMillis(false)));
... do something that takes more than one millisecond, but less than one second ...

The resulting sequence will repeat the same value, such as 1410543204000 , until the next second has started, at which time 1410543205000 will begin to repeat.

如果您想以特定模式获取日期和时间，您可以使用以下内容：

SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd_HHmmss");
String currentDateandTime = sdf.format(new Date());
