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?

Answer 1

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:

%1$td/%1$tm/%1$tY

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:

And in java class:

    MovieDetailViewModel vm = new MovieDetailViewModel();
    vm.setReleaseDate(new Date());
