android - Set arguments of fragment from activity -


i want pass arguments activity fragment, embedded activity. fragment embedded statically in xml layout. tried call setargument() this:

setcontentview(r.layout.detail_activity); detailfragment detailfragment = (detailfragment) getfragmentmanager().findfragmentbyid(r.id.detailfragment); detailfragment.setarguments(getintent().getextras());

but late, because setarguments has called after fragment's creation. see getarguments() , change bundle. better way?

afaik, can't use setarguments() when embed fragment within xml. if it's critical, you'd better off dynamically adding fragment instead. if want fragment embedded via xml, there different ways can pass along data.

  1. have activity implement fragment's event listener. have fragment request required parameters activity @ creation or whenever needed. communication fragment
  2. create custom attributes can embedded in xml along fragment. during fragment's inflation process, parse custom attributes obtain data. custom fragment attributes
  3. create public setters in fragment , have activity use them directly. if it's critical set them prior fragment's oncreate() method, activity's onattachfragment() method.

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
