there 3 strings, each length of string same, there spaces in strings. after fill 3 strings in listview control, find width of 3 row isn't same. how can make width of string same in android? thanks! btw, use android studio. min api 9. string1= "a b" string2= "aa b" string3= "aaa b" listview lv=(listview)findviewbyid(r.id.listview); string[] countries=new string[]{"a b","aa b","aaa b"}; lv.setadapter(new arrayadapter<string>(this, android.r.layout.simple_list_item_1, countries)); unless you're using monospaced font, achieving wanted going quite difficult. non-monospaced fonts has different width each of characters posses. however, there's workaround using layout arrangement. here's example: <?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:orient

i started learning regex in python. going through code extracting email address string. str = 'purple alice@google.com, blah monkey bob@abc.com blah dishwasher' emails1 = re.findall(r'[\w\.-]+@[\w\.-]+', str) emails2 = re.findall(r'[\w.-]+@[\w.-]+', str) is there difference between code emails1 , emails2? tested on 1 string , both giving same output. this first post here. please don't mind if post not according standards.thanks. the difference see . , \. , make difference. . stands "any character except newline" , \. being literal dot. however, in character classes [abcd.] means "any of following" characters . taken literary. since . both in charater class, there no difference between two. you should escape - in character classes though, since stands character range [a-z] . works in case because it's last character in class, don't want forget @ point , later on wonder "what's going wrong"

suppose want know whether string contains 5 or more continuous consecutive numbers. var = "ac39270982"; // false var = "000223344998"; // false var = "512345jj7"; // true - contains 12345 var = "aa456780"; // true - contains 45678 is there regex available accomplish this? able work in following situation? var = "5111213141587"; // true this should true because contains 11,12,13,14,15. i'm not sure if possible check provided examples (single-digit, double-digit numbers) larger numbers (triple-digit, etc.). i took time make 100% javascript approach question. made parse each character in string , integer comparison. works not 5 consecutive integers, works checking tenths (10's, 20's, etc). can increase/decrease number of comparisons if wish. a fair warning: despite method being potentially scalable if coded kinds of numeric sizes, you'd still bound computing power , number of comparisons. why provi

i very new writing code hoping out there me out couple of functions have in head! i have made button in edge animate , i’d add kind of jquery or code actions. basically, on timeline getting animation play points on different mouse events. on ‘rollover’, plays , stops halfway. on ‘click’ i’ve got playing next ‘label’ because mouse still hovering on button, ‘rollover’ function kinda trips whole thing , doesn’t know on timeline. i’d ‘rollover’ function disable after first mouse click. or ‘not’ play until ‘mouseout’ (after click). ideally (as extra) i’d toggle between 2 states on alternating clicks. so, click 1: play point (a), click 2: play point (b), . . . . (a), (b), (a), (b), ad infinitum! , whole thing should reset on mouseout!! that’s lot of work, hey? appreciate tips or suggestions… somewhere start from! muchly. a way via timeline duplicate button , change code on @ every label. first button has sym.play("b"); code on @ b label have identical button

if wanted check multiple conditions, can't use multiple if statements? example: a = 10 b = 20 if == b: print('equal') if < b: print('less') if > b: print('greater') using multiple if statements evaluate every if condition. conditions in example mutual exclusive, might have similar result. however, if a or b changes in-between, condition might become true: a = 5 b = 7 if < b: = b if == b: b += 1 both conditions evalute true , executed. might not intended, use: a = 5 b = 7 if < b: = b elif == b: b += 1 will execute first condition. even mutual exclusive conditions example, every expression has evaluated, slower second variant. note elif (aka else if ) identical to: if <cond1>: pass else: if <cond2>: pass else: if <cond3>: pass as can see, result in tests run out of text , less readable than: if <cond1>: pass elif <co
