Android Date-time format internationalization implementation code _android

In the long language version, the date and time format is a very frustrating thing, fortunately Android provides dateformate, can be formatted according to the default format of the specified language area.

Directly paste code:

Copy Code code as follows:

public static Charsequence Formattimeinlistforoverseauser (

Final context, Final long, final Boolean simple,

Locale Locale) {

Final GregorianCalendar now = new GregorianCalendar ();

Special time

if (Time < Millseconds_of_hour) {

Return "";

}

Today

Final GregorianCalendar today = new GregorianCalendar (

Now.get (Gregoriancalendar.year),

Now.get (Gregoriancalendar.month),

Now.get (Gregoriancalendar.day_of_month));

Final Long in24h = Time-today.gettimeinmillis ();

if (in24h > 0 && in24h <= millseconds_of_day) {

Java.text.DateFormat df = java.text.DateFormat.getTimeInstance (

Java.text.DateFormat.SHORT, Locale);

Return "" + Df.format (time);

}

Yesterday

Final Long in48h = Time-today.gettimeinmillis () + millseconds_of_day;

if (in48h > 0 && in48h <= millseconds_of_day) {

Return simple? Context.getstring (R.string.fmt_pre_yesterday)

: Context.getstring (R.string.fmt_pre_yesterday)

+ " "

+ Java.text.DateFormat.getTimeInstance (

Java.text.DateFormat.SHORT, Locale). Format (

Time);

}

Final GregorianCalendar target = new GregorianCalendar ();

Target.settimeinmillis (time);

Same week

if (Now.get (gregoriancalendar.year) = = Target

. Get (Gregoriancalendar.year)

&& now.get (gregoriancalendar.week_of_year) = = Target

. Get (Gregoriancalendar.week_of_year)) {

Java.text.SimpleDateFormat SDF = new Java.text.SimpleDateFormat ("E", locale);

Final String Dow = "" + Sdf.format (time);

Return simple? Dow:dow

+ Java.text.DateFormat.getTimeInstance (

Java.text.DateFormat.SHORT, Locale). Format (time);

}

Same year

if (Now.get (gregoriancalendar.year) = = Target

. Get (Gregoriancalendar.year)) {

Return simple? Java.text.DateFormat.getDateInstance (

Java.text.DateFormat.SHORT, Locale). Format (Time)

: Java.text.DateFormat.getDateTimeInstance (

Java.text.DateFormat.SHORT,

Java.text.DateFormat.SHORT, Locale). Format (time);

}

Return simple? Java.text.DateFormat.getDateInstance (

Java.text.DateFormat.SHORT, Locale). Format (Time)

: Java.text.DateFormat.getDateTimeInstance (

Java.text.DateFormat.SHORT, Java.text.DateFormat.SHORT,

locale). Format (time);

}

Note that this is java.text.DateFormat and there is another java.text.format.DateFormat, which cannot specify locale.
