MrKim Well-Known Member Licensed User Longtime User Aug 15, 2026 #1 Edit: This was my bad. The error was in my code. Ignore this thread. Using the code HERE I am adding a listview to the activity - tried adding it both to the activity and the root. I also tried adding the listview to a panel and then removing that. When I remove the list view from the activity or the root (tried adding it to both. The Root does not refresh and I am left with a blank screen. Activity.Invalidate Does not refresh the screen Rotating the device does. Example attached. Press the employee button.

Erel B4X founder Staff member Licensed User Longtime User Aug 16, 2026 #2 This is a large project and it is difficult to debug it without being familiar with the code. With E2E you need to add the Root view to the activity and from that point never add, remove or load layouts to the activity. Only to the Root view. Upvote 0

MrKim Well-Known Member Licensed User Longtime User Aug 21, 2026 #3 Sigh, my bad, deep in the code for this very large (and old) program is a routine called HideAll. It removes all views. I had to exclude Root. Updating these old apps is going to be a pain. And don't tell me update to pages. These are old apps that only have 20 or 30 users but they have been using them for 10 or 20 years and like them just the way they are. I have a Pages app that is cleaner that newer customers use but they don't like it. And we are one of those dumb companies that doesn't say tough shit and force the move. We actually try to give customers what they want. Here is what I did: Had this: B4X: For Each v As View In Activity.GetAllViewsRecursive v.Visible = False Next Added: B4X: Root.Tag = "Root" In Activity_Create and changed it to this: B4X: For Each v As View In Activity.GetAllViewsRecursive If Not(DCMod.Nz(v.Tag, "") = "Root") Then v.Visible = False End If Next Last edited: Aug 21, 2026 Upvote 0

Well, should I ask Erel to remove the thread.? That is what should happen since it was entirely my fault. I hate to see people wasting time reading this and the responses. As the solution it puts it right at the top. Perhaps I should put the code in that was the culprit and add the solution? Upvote 0
