java - Android: Cannot execute method with TextView -


this question has answer here:

i following beginner's android development course on udacity , have seemed come across simple error, though cannot life of me figure out or how search it.

there number increment , decrement button on sides change it. problem comes either when call displayquantity method or when tries set text of quantitytextview. value of quantity change, app closes before changes on screen.

    public void increment (view view){     quantity = quantity + 1;     displayquantity(quantity);     }      public void decrement (view view){     quantity = quantity - 1;     displayquantity(quantity);     }      private void displayquantity(int quantity) {     textview quantitytextview = (textview)  findviewbyid(r.id.quantity_text_view);     quantitytextview.settext(quantity); }

change to

quantitytextview.settext(integer.tostring(quantity));

textview.settext() overloaded. version takes integer expects resource identifier string resource (e.g. r.string.something), value passing doesn't correspond such resource.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
