java - Android Google Maps - remove marker with icon -


i want remove marker on long click, , place in place without clearing whole map.

right circle radius works fine, custom pin icon not removed. using googlemap.clear() method should not used - there other objects on map don't want refreshed. have tried setposition method , had same result. how erase icon?

marker declaration: 

marker = googlemap.addmarker(new markeroptions().position(marker.getposition()).draggable(true).title("info")                     .infowindowanchor(0.5f,0.5f).visible(false)                     .icon(bitmapdescriptorfactory.frombitmap(bitmapfactory.decoderesource(getresources(), r.drawable.pin_icon))));   this.googlemap.setonmaplongclicklistener(new googlemap.onmaplongclicklistener() {             @override             public void onmaplongclick(latlng latlng) {                 if (marker != null) {                     marker.remove();                 }                  createmarker(latlng);              }         });   private void createmarker(latlng latlng) {         marker = googlemap.addmarker(new markeroptions().position(latlng).draggable(true).title("info")                 .infowindowanchor(0.5f,0.5f)                 .icon(bitmapdescriptorfactory.frombitmap(bitmapfactory.decoderesource(getresources(), r.drawable.ic_pin_gr))));      }

i used such approach creating markers , setposition(new latlng(...)) working.

marker = mgooglemap.addmarker(new markeroptions()                     .anchor(0.5f, 0.5f)                     .icon(bitmapdescriptorfactory.fromresource(r.drawable.ic_pin))                     .position(new latlng(cab.getlatitude(), cab.getlongitude())));

did try replace marker.remove(); on setposition() inside onlongclick() method ?

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
