Android Question how to get the index from xcustomlistview in b4xswitch?

MbedAndroid · Sep 4, 2020

with the b4exviews switch i can do this operation:

B4X:

Private value As Object = MenuList.GetValue(MenuList.GetItemFromView(Sender))

i'm using this in a customlistview with multiple switches. To get which switch has been moved in the customlistview i use this code.

But when i switch to b4xswitch the code in customlistview crashes.
There must be a way to figure out which switch has been moved
The switch is dropped on a layout with panel, icon and text. so every line loads this layout. All the switches will have the same name.

Anyone did this before?
