android - Can't get coundown timer to work or display in my program -


i'm newer programmer , first project i'm having bit of trouble in making proper loop 3 timers supposed run 1 after other. managed objects hold values supposed within loop reason, timer isn't displaying in text field should.

          startbtn.setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view v) {             log.i("mtimer:", string.valueof(mtimer));             log.i("mreps:", string.valueof(mreps));             log.i("flexion:", string.valueof(flexiontimer));             log.i("hold:", string.valueof(holdtimer));             log.i("extension:", string.valueof(extensiontimer));              (int iter = 0; iter < mreps; iter++) {                 log.i("loop:", string.valueof(iter));                  final timer workingflexiontimer = new timer();                 workingflexiontimer.schedule(new timertask() {                     int counter = ((int) flexiontimer / 1000);                     @override                     public void run () {                         runonuithread(new runnable() {                             @override                             public void run() {                                 mphase.settext("flexion");                                 mcountdowntimer.settext("" + string.format(string.valueof(counter + 1)));                             }                         });                         if (counter-- == 0) {                             workingflexiontimer.cancel();                         }                     }                 }, 0, 1000);                   final timer workingholdtimer = new timer();                 workingholdtimer.schedule(new timertask() {                     int counter = ((int) holdtimer / 1000);                     @override                     public void run() {                         runonuithread(new runnable() {                             @override                             public void run() {                                 mphase.settext("hold!!!");                                 mcountdowntimer.settext("" + string.format(string.valueof(counter + 1)));                             }                         });                         if (counter-- == 0) {                             workingholdtimer.cancel();                         }                     }                 }, flexiontimer, 1000);                  final timer workingextensiontimer = new timer();                 workingextensiontimer.schedule(new timertask() {                     int counter = ((int) extensiontimer / 1000);                     @override                     public void run() {                         runonuithread(new runnable() {                             @override                             public void run() {                                 mphase.settext("extension");                                 mcountdowntimer.settext("" + string.format(string.valueof(counter + 1)));                             }                         });                         if (counter-- == 0) {                             workingextensiontimer.cancel();                         }                     }                 }, (flexiontimer + holdtimer), 1000);             }

i'm kind of @ loss @ point , suggestion appreciated.

update

for timers do:

    final textview textview = (textview)findviewbyid(r.id.textview);     timer timer = new timer();     timer.schedule(new timertask() {         int counter = 10;         @override         public void run() {             runonuithread(new runnable() {                 @override                 public void run() {                     textview.settext(""+counter);                 }             });              if (counter-- == 0){                 timer.cancel();             }          }     }, 0, 1000);  timer.schedule(new timertask() {         int counter = 10;         @override         public void run() {             runonuithread(new runnable() {                 @override                 public void run() {                     textview.settext(""+counter);                 }             });              if (counter-- == 0){                 timer.cancel();             }          }     }, 10000, 1000);   timer.schedule(new timertask() {         int counter = 10;         @override         public void run() {             runonuithread(new runnable() {                 @override                 public void run() {                     textview.settext(""+counter);                 }             });              if (counter-- == 0){                 timer.cancel();             }          }     }, 20000, 1000);

for more info check this

in link...

public void schedule(timertask task, long delay, long period)

the above code. start run() without delay. 

long delay = 0;// in ms long period = 1000;// in ms

so every 1000ms call run() , counter--. when counter = 0 cancel.

if want run, 1 after other, put delay.

update

now first run immediately, second wait 10000ms (10s) , run, finaly third wait 20000ms (20s) , run.

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 ...
