java - How to handle multiple spinner selected item comparison? -

-

i trying app display either text or image when 2 spinners selected values equal each other.

public class mainactivity extends appcompatactivity {      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);          spinner sp1 =(spinner)findviewbyid(r.id.sp1);         string txtfromspinner1 = sp1.getselecteditem().tostring();          spinner sp2 = (spinner)findviewbyid(r.id.sp2);         string txtfromspinner2 = sp2.getselecteditem().tostring();          if (txtfromspinner1.equals(1)&& txtfromspinner2.equals(2)){              textview textelement = (textview)findviewbyid(r.id.txresult);             textelement.settext("3");          }     } }

try this:

spinner sp1 =(spinner)findviewbyid(r.id.sp1); spinner sp2 = (spinner)findviewbyid(r.id.sp2); textview textelement = (textview)findviewbyid(r.id.txresult);               button showresult = (button)findviewbyid(r.id.btnshowresult);  showresult.setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view v) {            string txtfromspinner1 = sp1.getselecteditem().tostring();          string txtfromspinner2 = sp2.getselecteditem().tostring();           if (txtfromspinner1.equals("1")&& txtfromspinner2.equals("2"))                 textelement.settext("3");           }     });

i have date time below conversion logic in javascript converting utc time passed timezone's local time. wondering logic work fine during daylight transition? if not remedy that? can't use third party library. have use pure javascript or angular js. function mytime() { var d1= document.getelementbyid("txtdate").value; var zoffset = document.getelementbyid("txtoffset").value; console.log("date1",d1); var d2 = new date(d1.replace(/ /g,'t')); var d3= d2.gettime()+(d2.gettimezoneoffset()*60000); console.log("date2",d2); console.log("date3",d3); var d4 = new date(d3 + (3600000 * zoffset)); console.log("date3",d3); console.log("date 4",d4); var d5 = d4.tolocaletimestring(); console.log("date 5",d5); ...

Why does PHP consider 0 to be equal to a string? -

-
i have following piece of code: $item['price'] = 0; /*code item information goes in here*/ if($item['price'] == 'e') { $item['price'] = -1; } it intended initialize item price 0 , information it. if price informed 'e' means exchange instead of sell, indicated negative value because stored in database requires numeric value. there possibility leave price 0, either because item bonus or because price set in later moment. but, when price not set, leaves initial value of 0, if loop indicated above evaluates true , price set -1. is, considers 0 equal 'e'. how can explained? edit: when price provided 0 (after initialization), behavior erratic: if evaluates true, evaluates false. you doing == sorts out types you. 0 int, in case going cast 'e' int. not parseable one, , become 0 . string '0e' become 0 , , match! use ===

so let's have named vector: sorted = c(1,2,3) names(sorted) = c("a","b","c") and it'll following: > sorted b c 1 2 3 so vector named a,b,c, , has value 1,2,3 respectively. and have sample data: data.ex = as.data.frame(matrix(rep(c(1,2,3,4),3), nrow = 3, ncol = 3)) colnames(data.ex) = c("a","b","c") so data frame has 3 columns named a,b,c well. i want predict c using value in glm(): fit.ex = glm(formula = c ~ names(sorted)[2], data = data.ex, family = binomial(link = "logit")) but then, i'll keep getting following error message: error in model.frame.default(formula = c ~ names(sorted)[2], data = data.ex,: variable lengths differ (found 'names(sorted)[2]') i read article here , found as.name() function, still not working: http://www.ats.ucla.edu/stat/r/pages/looping_strings.htm and cannot find else thats similar problem. please, if the...
