How To Set DatePreferenc开发者_C百科e Default Value From Java Side.

I Want Set to Date "Now"

thanks.


I'm not exactly sure what you're asking about, as I don't know what a "DatePreference" is, and neither does Google.

With Java and Android, you have a few options for representing and working with date/time data. To represent "Now":

  • You could use java.util.Date. The no argument constructor creates a Date object that "represents the time at which it was allocated".

  • You could use java.util.Calendar. Calendar.getInstance() returns "a Calendar subclass instance set to the current date and time in the default Timezone".

  • You could use a primitive long value. System.currentTimeMillis() returns "the current time in milliseconds".

  • You could use android.text.format.Time, which is "a faster replacement for" Calendar. After constructing or otherwise obtaining a Time object, call setToNow() to set the time "to the current time".

  • Before Android, I know a lot of folks preferred to use Joda-Time when working with date/time data in Java. With Joda-Time, you could create a new joda.time.DateTime instance with the no argument constructor, which would then represent "the current system millisecond time using ISOChronology in the default time zone".

I also recommend reviewing the android.os.SystemClock documentation, when working with date/time events in Android.


I Found Solution This

dpDate.setDate(tools.NowDate());
