iOS Question xCustomListView Scroll Behavior

[Jim McDougal]

I have a TextView loaded into a panel which I add to a CustomListView. The panel height is larger than the CustomListView window height. Sometimes it will scroll the full length of the panel and sometimes it won't. A pretty basic implementation. Is there something I'm missing?

Not really simple. Combining scrollable views is problematic.

Is the text editable?

The TextView is not editable as I am embedding clickable links in it using CSBuilder. I was previously using ScrollView as I did in the B4A version of this app which worked fine, but in B4i the SCrollView and xCustomListView implementations both exhibit the same wonky behaviors. I will continue to tinker.

An example project that shows the behavior could also be helpful

If it is not editable then you can use CLV.AddTextItem. It will work better.

Not sure of the syntax. Can Attributed Text be passed as CLV.AddTextItem?

 

[Erel]

Yes.

 

[Jim McDougal]

OK, AttributedString does load into the CLV with AddTextItem. How do I expose the clickable links in the AttributedString? Since I don't have a TextView anymore there's no event to associate the links with. I only have the ItemClick event from the CLV and that returns Item number and Value.

Thanks for your help.

You will need a TextView if you want to handle the link click event.

You can disable the TextView scrolling: https://www.b4x.com/android/forum/threads/disable-scroll-textview.96865/#post-903000

Another option is to use BBListItem: https://www.b4x.com/android/forum/threads/b4x-bblistitem-bctextengine-inside-clv.131123/#content

I solved the problem by stacking individual labels, adding them to panels, and adding the panels to a ScrollView. It is a table of contents with expandable entries much like you'd see with Acrobat Reader. I expand/collapse the sublists by changing the height of the interior panels to show/hide the expanded list entries. The labels and panels are generated in code so that I don't have a ridiculously large designer layout.

Thanks for following up. I'm a bit more capable with both CLV and ScrollView now. I'll bookmark the two references above as well.
