Android Question Is this a BUG?! Why does this weird stuff happen?

[persianpowerman1]

guys...

I am comparing the selected item in a Listview... to a selected item in a Spinner

and you can see the log sheet for the corresponding values... ie..

ListView1.GetItem(list1_click) = 2
and
Spinner1.GetItem(spinner_click) = 2

so when i am comparing them..
this is suppose to be a TRUE... but in the IF Then condition.. it jumps to ELSE??? why is that???
(list1_click and spinner_click)... are only to save the array No. of the item selected
is there something wrong with the code??? or does it not work with numbers????

YO!han

The thread title should describe the issue or question.
Can you post the complete project (File - Export as zip)?

 

[persianpowerman1]

yes i can.. will be home in 2hrs.. will do so...

however it works with string. . not with numbers?!?!

Persianpowerman,
I had similar issues only it was comparing values from a Button.Tag. If I logged both values they appeared the same, but in a compare weren't!
I suspect it was a issue of variable types, so I solved it by explicitly forcing them to be integers I.e.

dim lval, sval as int
lval = ListView1.GetItem(list1_click)
sval = Spinner1.GetItem(spinner_click)
Log(lval=sval)

It worked for me,

hey douglas.. thats what i did too.. then it worked
i saved both of them in variables.. and then compared them... it did work!
But still ... its weird.. beats my logic!?!

Erel... buddy.. heres the stuff.. i was doing a lill RnD with them... the click event of Button1 is where i got stuck...
its where im comparing a selected item from the LISTVIEW with a selected item from SPINNER

the click event of Button2.. works fine...

One is a char and one is a numeric..

 

[persianpowerman1]

hi eps,
could you tell me..
how would you find that out?

 

[Erel]

You are comparing 2 with "2". The compiler cannot know the type because the variables type in this case is Object.
You should explicitly set the type.
For example:

Dim s1 = ListView1.GetItem(list1_click), s2 = Spinner1.GetItem(spinner_click) As String
If s1 = s2 ...

Note that you should use File - Export as zip when uploading projects.
