trying display correctly in both landscape , portrait mode when 1 works other not.

any suggestions on how go doing this?

in these cases create other invisible dummy buttons below , align these in such way "real" buttons positioned correctly.

if dummy buttons pushed off screen that's fine, real buttons above them. if there little stuff on screen dummy buttons @ bottom , "real" buttons somewhere in middle.

make "invisible" buttons width = "1dp" , height as need. leave them visible in android sense

edit: create relativeview aligns bottom bottom of list view , give maxheight. align buttons below relative view. when listview small buttons positioned right below it, if listview long relative view exceeds maxheight , ensures still on screen buttons right below maxheight. make sure maxheight of relativeview leaves enough room on bottom of screen buttons.

to adjust maxheight leaves enough room buttons on screen size may use screensize of device , adjust maxhight accordingly screenheight:

display display = getwindowmanager().getdefaultdisplay(); point size = new point(); display.getsize(size); int screenhheight = size.y;

hope helps in case...

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...
