Android ScrollView scrollTo() method not working with TextView? -

-

for example, have layout this:

<scrollview>   <linearlayout>     <linearlayout>          ...     </linearlayout>     <linearlayout>          ...     </linearlayout>     <linearlayout>          <textview>          </textview>     </linearlayout>   </linearlayout> </scrollview>

my textview have long content. can scroll scrollview manually end of textview content. in code, write: scrview.scrollto(0, 800);, scrview scrollview. supposed scroll middle of textview content. when running, scrolled start of textview , can't scroll through textview content.

does know causing problems?

edit: found it. seems call scrollto soon. using 

scrview.post(new runnable() {                 public void run() {                     scrview.scrollto(0, 800);                 }             });

instead , works. posted answer getting same problem.

first of all, if linearlayouts have same orientation, why don't create once? if i'm not wrong, scrollview can have 1 child (1 direct child). maybe that's reason of problems. however, if still want 3 linearlayouts, can create framelayout parent hold them , make framelayout child of scrollview

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...
