i have been developing android while , have never come across before im hoping 1 here can help. have multiple edittext's , autocompletextviews populate sharedprefs. problem views not displaying text should be. display old value there until leave activity , come back. strange part if call gettext function on edittext when has wrong value displayed gettext() returns correct value. can please explain why might be. public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate){ view = inflater.inflate(r.layout.extra_info, container, false); myprefs = preferencemanager .getdefaultsharedpreferences(getactivity()); initprefs(); findtextviews(); findviews(); initdatasource(); runqueries(); getallfields(); return view; } private void findviews() { editpayid = (autocompletetextview)view.findviewbyid( r.id.editpayid )

i have custom view controller called timerviewcontroller , subclasses of called firstviewcontroller , fourthviewcontroller . i declared instance of firstviewcontroller in firstviewcontroller 's . h named controller . in viewdidload method of fourthviewcontroller 's .m , have: controller = [self.storyboard instantiateviewcontrollerwithidentifier:@"maincontroller"]; in storyboard, i've declared view controller id maincontroller , declared custom class of fourthviewcontroller . then, in fourthviewcontroller 's .m have: controller.mainlab.text = [nsmutablestring stringwithformat:@"this string"]; nslog(@"%@", controller.mainlab.text); this, however, outputs (null) . why happen? mainlab must nil . outlet isn't connected xib. as aside, using stringwithformat: string isn't format wasteful.

is there way click on div , save click sequence value in db. say have ten items in 10 small small divs , want them sorted in sequence click on them. clicking on first 1 sorted first , next , next. want able javascript. have seen happening in desktop application form fields sequenced tab order click on fields. i can give conceptual format, because full-fledged deal quite long, , because you've posted no code . ensure each div has unique id, , has @ least 1 common css class e.g. sortable - critical, allow query dom elements further sorting. and, regarding ideas id of divs, have seen variations of identifier post id database; you have listening function run when window loaded, listens when div has class sortable clicked. override default action, , use class in tandem div id keep record of elements clicked , sort them accordingly whatever criteria deem fit (id, date, content). however, have manipulate dom modified represent new ordering. can done in 2 further way

rails provide strong template engine out of box , it. wondering if there way use it? maybe angular templates can wrapped inside rails lives in our views directory. can call metatemplates. so instead of angular templates living in asset directory feel not way? also need make use of rails routes inside angular @ point. example signout functionality. afaik, let ruby serve angular templates. angular requesting resource server via url, , expects html fragment. if angular requesting rails, use rails functionality serve html fragment (ie template). write angular templates rails partial using erb or haml, rails serve html requester. as side note, gets complicated separate concerns doing approach. keep clear in mind rails needs application server, , rails needs application service. application server needs serve angular application (i.e. js , html managed angular on client side). application service needs serve json consumed angular.

i have generall concern. wrote simple viewpager in html/css/javascript allows me swipe between "pages" using viewpager in android and/or iphone. required javascript less 1kb. when converted clojurescript, resulting code optimizations , lack of pretty printing, ended @ around 62kb. what i'm concerned with, clojurescript big , more regular javascript, full fledged mobile application, slow. can put mind @ ease? have experience this? there's quite bit of clojure's data structures , core library functions have compiled js, of 60kb. wouldn't worry javascript size since in mobile apps other assets (i.e., images) dominate size. speed, usual rules apply: careful dom manipulations , layout/repaint. for it's worth, the weathertron ios application written clojurescript + angular.js , performs fine.
