| ↳ | android.text.format.DateFormat |
Utility class for producing strings with formatted date/time.
Most callers should avoid supplying their own format strings to this
class'
format
methods and rely on the correctly localized ones
supplied by the system. This class' factory methods return
appropriately-localized
DateFormat
instances, suitable
for both formatting and parsing dates. For the canonical documentation
of format strings, see
SimpleDateFormat
.
In cases where the system does not provide a suitable pattern,
this class offers the
getBestDateTimePattern(Locale, String)
method.
The
format
methods in this class implement a subset of Unicode
UTS #35
patterns.
The subset currently supported by this class includes the following format characters:
acdEHhLKkLMmsyz
. Up to API level 17, only
adEhkMmszy
were supported.
Note that this class incorrectly implements
k
as if it were
H
for backwards
compatibility.
See
SimpleDateFormat
for more documentation
about patterns, or if you need a more complete or correct implementation.
Note that the non-
format
methods in this class are implemented by
SimpleDateFormat
.

CharSequence
containing the requested text
Returns the best possible localized form of the given skeleton for the given locale. A skeleton is similar to, and uses the same format characters as, a Unicode UTS #35 pattern.
One difference is that order is irrelevant. For example, "MMMMd" will return
"MMMM d" in the
en_US
locale, but "d. MMMM" in the
de_CH
locale.
Note also in that second example that the necessary punctuation for German was
added. For the same input in
es_ES
, we'd have even more extra text:
"d 'de' MMMM".
This method will automatically correct for grammatical necessity. Given the
same "MMMMd" input, this method will return "d LLLL" in the
fa_IR
locale,
where stand-alone months are necessary. Lengths are preserved where meaningful,
so "Md" would give a different result to "MMMd", say, except in a locale such as
ja_JP
where there is only one length of month.
This method will only return patterns that are in CLDR, and is useful whenever you know what elements you want in your format string but don't want to make your code specific to any one locale.

DateFormat
object that properly formats the date.
Gets the current date format stored as a char array. The array will contain
3 elements (
DATE
,
MONTH
, and
YEAR
) in the order
specified by the user's format preference. Note that this order is
only
appropriate for all-numeric dates; spelled-out (MEDIUM and LONG)
dates will generally contain other punctuation, spaces, or words,
not just the day, month, and year, and not necessarily in the same
order returned here.
Returns a

Monday, January 3, 2000
) for the current locale.
