android - Fragment inside fragment not working -


i have made fragment inside fragment , when click on list item in list , works because toast method shows message new fragment not adding... shows remains same....

   @override         public void onitemclick(adapterview<?> parent, view view, int position, long id) {             textview t_profile_name = (textview) view.findviewbyid(r.id.profile_name);              textview t_profile_hometown = (textview) view.findviewbyid(r.id.profile_hometown);               string user_name = t_profile_name.gettext().tostring();              string  user_hometown = t_profile_hometown.gettext().tostring();              string getid = user_id[position];              sharedpreferences sharedpreferences = getactivity().getsharedpreferences("comm_data", getcontext().mode_private);             string getid = sharedpreferences.getstring("user_id", "");              toast.maketext(getcontext(), user_name+" "+user_hometown+" "+getid+""+getid, toast.length_short).show();                //msocket.emit("message", "getuser");             fragmentmanager fragmentmanager = getchildfragmentmanager();             fragmenttransaction fragmenttransaction = fragmentmanager.begintransaction();             fragmenttransaction.add(new chat_box(),"chat_box");             fragmenttransaction.addtobackstack("chat");             fragmenttransaction.commit();

you should tell fragment manager add fragment somewhere. @mike said, use fragmenttransaction#add(int,fragment, string). code should fragmenttransaction.add(r.id.the_container,new chat_box(),"chat_box");

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 ...
