android - No preview of custom views on UI designer in Eclipse -


background

i've been creating many types of custom views, , previews shown fine on ui designer of adt.

lately, after updating newest version of adt ( 22.0.5.v201307292155--757759 ), can't see type of custom view, not simplest 1 .

the problem

now, know sure custom views can previewed fine , since if create new workspace , create them, can see them fine.

the problem on current workspace, has many settings projects, keep getting error:

the following classes not found: - ... (change ... , fix build path, edit xml, create class)

where "..." class of custom view.

i gray rectangle each custom view use, , lint complains:

class referenced in layout file, ..., not found in project or libraries

this weird, since used correct syntax custom views in xml (and i've done lot). drag&drop didn't help.

it's weird because eclipse can find classes (using ctrl+click on xml tag goes right correct class) , doesn't seem find them while viewing.

i've tried uninstall adt , reinstall it, didn't help. i've tried uninstall , re-install relevant components sdk manager. nothing helped.

here's sample code of custom view doesn't show @ :

public class customtextview extends textview {      public customtextview(context context) {         super(context);     }      public customtextview(context context, attributeset attrs) {         super(context, attrs);     }      public customtextview(context context, attributeset attrs, int defstyle) {         super(context, attrs, defstyle);     } }

as can see, there nothing special in code.

the question

why occur? how can fix it? can perhaps copy (and mean all) settings of current workspace new 1 solve it?

does else have problem? adt bug?

note: not want reset workspace. has far many special settings projects within it.

did update eclipse plugin adt?

i know happened me once missed.

maybe if there updates actual platform sdk's update them well. can try change version of sdk preview uses latest or earlier 1 (this android icon on top left in preview should 18).

i know custom views don't render if use shadows example on text. set isineditmode flag inside custom view skip those.

at end download new zip adt bundle , try again :)

hope helps somehow.

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...
