3. Get Current Date Android

The simple display current date and time app that can simply show the current time and date on your phone screen, may be in some unique way. You will also be shown a count down of every passing second so there is a hour, minute and a second display in the watch. If the time over 10 minutes, do a new comparission to update registederOffsetFromInternetTime and mantain accuracy. If the user uses the App without Internet, we can only use the registederOffsetFromInternetTime stored as reference, and use it. Just if the user changes the hour in local device when offline and use the app.

How can I get the current time and date in an Android app?

You could use:

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

Edit:
Check Calendar class documentation

ColdFire

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

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

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.

If you want to get the date and time in a specific pattern you can use the following:

Or,

For those who might rather prefer a customized format, you can use:

Whereas you can have DateFormat patterns such as:

Peter MortensenANematiANemati

Actually, it's safer to set the current timezone set on the device with Time.getCurrentTimezone(), or else you will get the current time in UTC.

Then, you can get all the date fields you want, like, for example:

See android.text.format.Time class for all the details.

UPDATE

As many people are pointing out, Google says this class has a number of issues and is not supposed to be used anymore:

Usb driver for windows 2000 free download - Virtual Printer Driver for Windows 2000, Synaptics Touchpad Driver for Windows 2000 WinXP Version 7.6.5.zip, VIA USB 2.0 Host Controller Driver,. Feb 18, 2003  End Of Life - This download, USB 2.0 Signature Drivers for Windows. 2000 W2KUSB20.EXE 5.1, will no longer be available after October, 29, 2019 and will not be supported with any additional functional, security, or other updates. All versions are provided as is. Intel recommends that users of USB 2.0 Signature Drivers for Windows. 2000 W2KUSB20.EXE 5.1 uninstall.

This class has a number of issues and it is recommended that GregorianCalendar is used instead.

Known issues:

For historical reasons when performing time calculations all arithmetic currently takes place using 32-bit integers. This limits the reliable time range representable from 1902 until 2037.See the wikipedia article on the Year 2038 problem for details. Do not rely on this behavior; it may change in the future. Calling switchTimezone(String) on a date that cannot exist, such as a wall time that was skipped due to a DST transition, will result in a date in 1969 (i.e. -1, or 1 second before 1st Jan 1970 UTC). Much of the formatting / parsing assumes ASCII text and is therefore not suitable for use with non-ASCII scripts.

Try with this way All formats are given below to get date and time format.

AmitsharmaAmitsharma

To ge the current time you can use System.currentTimeMillis() which is standard in Java. Then you can use it to create a date

And as mentioned by others to create a time

JosephLJosephL

You can use the code:

Output:

You also get some more formatting options for SimpleDateFormat from here.

The other Answers, while correct, are outdated. The old date-time classes have proven to be poorly designed, confusing, and troublesome.

Those old classes have been supplanted by the java.time framework.

• Java 8 and later: The java.time framework is built-in.
• Java 7 & 6: Use the backport of java.time.
• Android: Use this wrapped version of that backport.

These new classes are inspired by the highly successful Joda-Time project, defined by JSR 310, and extended by the ThreeTen-Extra project.

See the Oracle Tutorial.

Instant

An Instant is a moment on the timeline in UTC with resolution up to nanoseconds.

Time Zone

Apply a time zone (ZoneId) to get a ZonedDateTime. If you omit the time zone your JVM’s current default time zone is implicitly applied. Better to specify explicitly the desired/expected time zone.

Use proper time zone names in the format of continent/region such as America/Montreal, Europe/Brussels, or Asia/Kolkata. Never use the 3-4 letter abbreviations such as EST or IST as they are neither standardized nor unique.

Generating Strings

You can easily generate a String as a textual representation of the date-time value. You can go with a standard format, your own custom format, or an automatically localized format.

ISO 8601

You can call the toString methods to get text formatted using the common and sensible ISO 8601 standard.

2016-03-23T03:09:01.613Z

Note that for ZonedDateTime, the toString method extends the ISO 8601 standard by appending the name of the time zone in square brackets. Extremely useful and important information, but not standard.

2016-03-22T20:09:01.613-08:00[America/Los_Angeles]

Custom format

Or specify your own particular formatting pattern with the DateTimeFormatter class.

Specify a Locale for a human language (English, French, etc.) to use in translating the name of day/month and also in defining cultural norms such as the order of year and month and date. Note that Locale has nothing to do with time zone.

Localizing

Better yet, let java.time do the work of localizing automatically.

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Fully localized language pack: It contains 100 percent of the resources for a language and locale. Language Interface Pack (LIP): A partially localized language pack that includes less than 100 percent of the localized resources. Partially localized language pack: It contains 100 percent of the resources for a language and locale, but not all of the resources are localized in the language pack.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Easy, you can dissect the time to get separate values for current time, as follows:

Same goes for the date, as follows:

There are several options as Android is mainly Java, but if you wish to write it in a textView, the following code would do the trick:

Peter MortensenAlex MuriithiAlex Muriithi

This is a method that will be useful to get date and time:

You can call this method and get the current date and time values:

JorgesysJorgesys

This will give you, for example, 12:32.

Remember to import android.text.format.Time;

Peter Mortensendugguduggu

You can also use android.os.SystemClock.For example SystemClock.elapsedRealtime() will give you more accurate time readings when the phone is asleep.

For a customized time and date format:

Output is like below format: 2015-06-18T10:15:56-05:00

If you need current date,

If you need current time,

You can obtain the date by using:

This will give you a result in a nice form, as in this example: '2014/02/09'.

For the current date and time with format, Use

In Kotlin

MacaronLover

Well I had problems with some answers by the API so I fuse this code, I hope it serves them guys:

Output: 03:25 PM - 2017/10/03

Below method will return current date and time in String, Use different time zone according to your actual time zone.I've used GMT

You should use Calender class according to new API. Date class is deprecated now.

You cannot on a normal off the shelf handset, because it's not possible to gain the SET_TIME permission. This permission has the protectionLevel of signatureOrSystem, so there's no way for a market app to change global system time (but perhaps with black vodoo magic I do not know yet).

You cannot use other approaches because this is prevented on a Linux level, (see the long answer below) - this is why all trials using terminals and SysExecs gonna fail.

If you CAN gain the permission either because you rooted your phone or built and signed your own platform image, read on.

Short Answer

It's possible and has been done. You need android.permission.SET_TIME. Afterward use the AlarmManager via Context.getSystemService(Context.ALARM_SERVICE) and it s method setTime().

Snippet for setting the time to 2010/1/1 12:00:00 from an Activity or Service:

If you which to change the timezone, the approach should be very similar (see android.permission.SET_TIME_ZONE and setTimeZone)

Long Answer

As it has been pointed out in several threads, only the system user can change the system time. This is only half of the story. SystemClock.setCurrentTimeMillis() directly writes to /dev/alarm which is a device file owned by system lacking world writeable rights. So in other words only processes running as system may use the SystemClock approach. For this way android permissions do not matter, there's no entity involved which checks proper permissions.

This is the way the internal preinstalled Settings App works. It just runs under the system user account.

For all the other kids in town there's the alarm manager. It's a system service running in the system_server process under the - guess what - system user account. It exposes the mentioned setTime method but enforces the SET_TIME permission and in in turn just calls SystemClock.setCurrentTimeMillis internally (which succeeds because of the user the alarm manager is running as).

According to this thread, user apps cannot set the time, regardless of the permissions we give it. Instead, the best approach is to make the user set the time manually. We will use:

Unfortunately, there is no way to link them directly to the time setting (which would save them one more click). By making use of ellapsedRealtime, we can ensure that the user sets the time correctly.

A solution for rooted devices could be execute the commands

• su
• date -s YYYYMMDD.HHMMSS

You can do this by code with the following method:

Just call the previous method like this:

Led MachineLed Machine

I didn't see this one on the list anywhere but it works for me. My device is rooted and I have superuser installed, but if superuser works on non-rooted devices, this might work. I used an AsyncTask and called the following:

In our application case, the dirty workaround was:

When the user is connected to Internet, we get the Internet Time (NTP server) and compare the difference (-) of the internal device time (registederOffsetFromInternetTime). We save it on the config record file of the user.

We use the time of the devide + registederOffsetFromInternetTime to consider the correct updated time for OUR application.

All GETHOUR processes check the difference between the actual time with the time of the last comparission (with the Internet time). If the time over 10 minutes, do a new comparission to update registederOffsetFromInternetTime and mantain accuracy.

If the user uses the App without Internet, we can only use the registederOffsetFromInternetTime stored as reference, and use it. Just if the user changes the hour in local device when offline and use the app, the app will consider incorrect times. But when the user comes back to internet access we warn he about the clock changed , asking to resynchronize all or desconsider updates did offline with the incorrect hour.

thanks penquin. In quickshortcutmaker I catch name of date/time seting activity exactly. so to start system time setting:
