Android Question CLV Index and msgbox

Hi
I have a msgbox that when the user chose Yes the app gets the current clv index from a label click and then do other stuff but im getting this error

Code:

java.lang.ClassCastException: android.app.AlertDialog cannot be cast to android.view.View

java.lang.ClassCastException: android.app.AlertDialog cannot be cast to android.view.View

when i try to excute this line

Code:

Dim index As Int = CLV1.GetItemFromView(Sender)

It work fine without the msgbox

Here is the full code

Code:

Dim xui As XUI


    Dim sf As Object = xui.Msgbox2Async("Delete file?", "", "Yes", "", "No", Null)
    Wait For (sf) Msgbox_Result (Result As Int)
    If Result = xui.DialogResponse_Positive Then
            Dim index As Int = CLV1.GetItemFromView(Sender)
Log(Index)
End If

 

It happens because the Sender is the xui.Msgbox2Async, cannot be a View from your CLV (that way).

 

its not xui related as it gives the same error with normal msgbox

 

Help us helping you. Upload a small project which shows the issue

 

The Sender is the "object" (almost always a View) that has fired the event, so to get the item "from Sender", you have to Click, Touch or other on a View which is part of the item. You are instead waiting for an event fired by a MsgBox (xui or not), so the Sender is part of this one.

 

The project is currently empty and the code i posted is the only code in it at the current stage of the project

 

So ...
How can i get the current clv index with a msgbox? Any samples perhaps?

 

Given your code in post # 1, I suppose your CLV shows a list of files and you want to give the user the option to delete a (selected) file.
So you should show your msgbox (async) inside the CLV1_ItemClick(Index As Int, Value As Object) event, which returns the Index of the Item clicked and also the Value you associated to that Item. Or in the Click event of the clicked View, like: Sub lblFileName_Click, and here you can useCLV1.GetItemFromView(Sender).
