Click to expand...


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...

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

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!

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?

error occured in this sub :

B4X: 
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
