How to format date and time in Android

Question

How to format correctly according to the device configuration date and time when having a year  month  day  hour and minute

User · Answer

Back to 2016  When I want to customize the format  not according to the device configuration  as you ask     I usually use the string resource file   in strings xml    lt string name  myDateFormat  gt  lt xliff g id  myDateFormat  gt  1 td  1 tm  1 tY lt  xliff g gt  lt  string gt    In Activity   Log d TAG   my custom date format    getString R string myDateFormat  new Date        This is also useful with the release of the new Date Binding Library   So I can have something like this in layout file    lt TextView     android id    id text release date      android layout width  wrap content      android layout height  0dp      android layout weight  1      android padding  2dp      android text     string myDateFormat vm releaseDate        tools text  0000        gt    And in java class       MovieDetailViewModel vm   new MovieDetailViewModel        vm setReleaseDate new Date

In my opinion  android text format DateFormat getDateFormat context  makes me confused because this method returns java text DateFormat rather than android text format DateFormat - -    So  I use the fragment code as below to get the current date time in my format   android text format DateFormat df   new android text format DateFormat    df format  yyyy-MM-dd hh mm ss a   new java util Date      or  android text format DateFormat format  yyyy-MM-dd hh mm ss a   new java util Date       In addition  you can use others formats  Follow DateFormat

The other answers are generally correct  I should like to contribute the modern answer  The classes Date  DateFormat and SimpleDateFormat used in most of the other answers  are long outdated and have caused trouble for many programmers over many years  Today we have so much better in java time  AKA JSR-310  the modern Java date  amp  time API  Can you use this on Android yet  Most certainly  The modern classes have been backported to Android in the ThreeTenABP project  See this question  How to use ThreeTenABP in Android Project for all the details   This snippet should get you started       int year   2017  month   9  day   28  hour   22  minute   45      LocalDateTime dateTime   LocalDateTime of year  month  day  hour  minute       DateTimeFormatter formatter   DateTimeFormatter ofLocalizedDateTime FormatStyle MEDIUM       System out println dateTime format formatter      When I set my computer   s preferred language to US English or UK English  this prints   Sep 28  2017 10 45 00 PM   When instead I set it to Danish  I get   28-09-2017 22 45 00   So it does follow the configuration  I am unsure exactly to what detail it follows your device   s date and time settings  though  and this may vary from phone to phone

Back to 2016  When I want to customize the format  not according to the device configuration  as you ask     I usually use the string resource file   in strings xml    lt string name  myDateFormat  gt  lt xliff g id  myDateFormat  gt  1 td  1 tm  1 tY lt  xliff g gt  lt  string gt    In Activity   Log d TAG   my custom date format    getString R string myDateFormat  new Date        This is also useful with the release of the new Date Binding Library   So I can have something like this in layout file    lt TextView     android id    id text release date      android layout width  wrap content      android layout height  0dp      android layout weight  1      android padding  2dp      android text     string myDateFormat vm releaseDate        tools text  0000        gt    And in java class       MovieDetailViewModel vm   new MovieDetailViewModel        vm setReleaseDate new Date
