android - How to get a arraylist<bitmap> from gridview -


i setting shuffled arraylist in grid view after rearranging want arraylist in order there in gridview . used getchildat(position) returning view.

here code:

   (int = 0; < smallimages.size(); i++) {    //     arraylist<view>bh=new arraylist<>(9);         beforeshuffle.add(smallimages.get(i));       //  smallimageadapter ad=new smallimageadapter(c,beforeshuffle);       }       collections.shuffle(smallimages);     image_grid.setadapter(new smallimageadapter(this, smallimages));   //  image_grid.setadapter(new smallimageadapter());      image_grid.setnumcolumns((int) math.sqrt(smallimages.size()));     image_grid.setonitemclicklistener(new adapterview.onitemclicklistener() {         int counter = 0;         int firstclick;          @override         public void onitemclick(adapterview<?> parent, view view, int position, long id) {             counter++;             if (counter % 2 == 0) {                 firstclick = position;                 bitmap data1 = smallimages.get(position);              } else {                       bitmap swapimage = smallimages.get(position);                     smallimages.set(position, smallimages.get(firstclick));                     smallimages.set(firstclick, swapimage);                     image_grid.invalidateviews();               }           //  arraylist<view>h=new arraylist<view>(9);              (int i=0;i<smallimages.size();i++) {                 aftershuffle.set(i, smallimages.get(i));              }             }      });

this aftershulffle not in same order images place in grid view. when check

beforeshuffle.get(1).sameas(aftershuffle.get(1))

it returns false

you can use settag() , gettag() on view store custom class objects , ex: imageview.settag(person).

later can call person person = (person)getchildat(position).gettag()

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
