I would like to make a label visible while the user has the mouse pressed over the scrollbar in a CustomListView, and then become invisible when the user releases the mouse button.
Is there any code that will allow me to do this (using reflection, or java object on the Scrollbar for example)?

It will be simpler to show the label while the list is scrolled using the ScrollChanged event.

Might be easy to make visible, not so easy to finish without timers?

Another option is to add an event filter with jReflection.

I'd like to use this option. Can anyone point me to where I can figure out what object I have to set as the reflection object, and what the syntax will be for the event?

Easy:
B4X: 
Sub CLV_ScrollChanged (...)
 if lbl.Visible = False Then lbl.SetVisibleAnimated(300, True)
 ScrollChangedIndex = ScrollChangedIndex + 1 'Global Int variable
 Dim MyIndex As Int = ScrollChangedIndex
 Sleep(500)
 If MyIndex = ScrollChangedIndex Then lbl.SetVisibleAnimated(300, False)
End Sub

Still looking for how to set up an event filter with jReflection. What would be my jReflection target to filter the Scrollbar button?
