android - executor service + view.post(Runnable) -

-

i want start several threads, retrive data net, perform actions , change ui regarding data.

i'm using executor service

executorservice = executors.newfixedthreadpool(3);

all data get, when try invoke imageview.post returns true body of regarding runnable not executed:

log.v("imageloader", "before post + " + imageview); imageview.post(new runnable() {     @override     public void run()     {          log.v("imageloader", "in post - " + bmptoshow.tostring() + "/" + imageview);          if (imageview.gettag().equals(url))          {              imageview.setimagebitmap(bmptoshow);          }     } });

if execute 10 runnables in executor service in log can find 10 "before post" messages, ntasks (depends on how many task allow in "executors.newfixedthreadpool(ntasks)") "in post" messages

i can't figure out how ntasks connects number of view.post runs.

ps. happens first start of app (i use android fragments , fill data in oncreateview)

wow, problem in cases (i dont know on depends) code in imageview.post not performed (maybe view not created yet), changed imageview.post() on runonuithread() , works now.

c# - Copy ObservableCollection to another ObservableCollection -

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
