Android Question Custom list view how can I tell if scroll is visible?

[Addo]

How do I know if custom list view scrolling is visible?

I tried clv.sv.visible but it returns true, no matter if I have 1000 items or only 1 item

 

[Erel]

What do you mean with scroll? The vertical line on the right side?

 

[Addo]

@Erel yes

You can handle the ScrollChanged event. It will more or less match the visibility of this indicator.

 

[Addo]

The thing is if i have no items the scroll changed event will not be called

 

[Addo]

As example
If I have a global variable

Dim IsClvscrollvisible as boolean

If there is one item or not many items the Scroll changed event will not be fired to set this variable accordingly

 

[Erel]

What are you trying to do?

 

[Addo]

I am trying to detect some changes in the customlistview when the scrolling is visible

 

[Addo]

I have also tried to get the property with java object

Dim jo As JavaObject = clv
Log(jo.GetField("_scrollbarsvisible"))

always return true whether its visible or not

 

[Erel]

The scrolling indicator will not change anything.

 

[Addo]

I don't get it, I assume that it is not possible to tell if scrollbars is visible or not visible in customlistview.

 

[Addo]

a small workaround but not perfect

If clv.sv.ScrollViewContentHeight > clv.AsView.Height Then
log("we have scrollbars")
else
log("No scrollbars")
end if
