those lines are ok, it has something to do with the class, i dont have those libs so i cannot not test it.

btw you should put "if firsttime = true then..." in activity create unless your code will every activity start load 10 new items to your listview
or you can clear the items before you add new items...

views that has been created in designer should not be intialized...

 

[ilan]

when i try the code my listview get filled like it should be, only after i slide i get an error (something with class... but again i have not those libs so i removed the LockScreenController lines)

and i also use b4a 4.3

Damn you are right : didn't saw it was created in the designer

 

[Cableguy]

... load 10 new items to your listview
or you can clear the items before you add new items...

actually 0 to 10 will cycle 11 times thus going from 0 to 10 = 11 items

 

[ilan]

actually 0 to 10 will cycle 11 times thus going from 0 to 10 = 11 items

you are right, i believe he understood my point

 

[Cableguy]

you are right, i believe he understood my point

I just mentioned that because i have too many times forgoten than an index begins at 0. And that an array lenght counts the actual amout of items in it, so the last index is length - 1!

 

[khosrwb]

when I run this program and use from them
show error on line 469 in class module (( ClsSlidingSideBar ))
and when remove this code from Activity module (( LockScreen )) program worked truly

For i=0 To 10
    listview1.AddTwoLines(i,i)
Next

I don't know what is the problem
please help me

 

[RandomCoder]

I'm sorry but I've not got my PC to hand at the moment so can't check the code you have already uploaded. Please show the code on line 469 where the error occurs. It's it possible that you are trying to access a property of the ListView that doesn't exist and so throwing the ClassCast error?

 

[khosrwb]

error occured in this sub :

Private Sub GetViewAtXY(X As Float, Y As Float) As Object
    For Each v As View In pnlContent.GetAllViewsRecursive
        If X >= v.Left And X <= v.Left + v.Width And Y >= v.Top And Y <= v.Top + v.Height Then       'this line is 469
            Return v
        End If   
      Next
    Return Null
End Sub
