B4A Library [B4X] [XUI] AS MultiColumnCustomListView based on xCustomListView

Hello this is a mutli column custom list view. You can add 1-100 columns, the screen is the limit. The items can have different heights.

I spend a lot of time in creating views, like this and to create a high quality view cost a lot of time. If you want to support me and further views, then you can do it here by Paypal or with a coffee.

If a stress test is performed on the view, unwanted behavior can occur, but this does not happen in normal operation. Remember to always test in release mode!

Customlistview with 2 columns and different heights

I saw this post: https://www.b4x.com/android/forum/threads/customlistview-with-2-or-more-columns.118135/ but I want to create a customlistview with 2 columns and different heights. The cell will adjust according to content. Is like the image below. Any tips to make this? Thanks in advance.

You may want to check the Sub AS_MultiColumnCustomListView1_ItemClick (Index As Int, Value As Object)
The event does not fire.

Is there any optimization for performance? For example, I load hundreds of views, each containing an image and 2 labels. like PreoptimizedCLV.

My views all only support the top menu.

My views all only support the top menu.

I don't think we need to do anything special for the context menu. I had never used it, to be honest, but I see and can add my B4XLib-Views that way too.
I assume the two menus are actually the same.

Are you sure? And if so, why?

It's only been reported to me twice so far and I have no idea what the problem is, but it sounds stressful to fix it in all 60+ libraries just because 2 people use the menu.

I think it's a mistake made by those two people

I have to correct myself, I didn't even know that you can add views with a right click in the views tree, but even if you use the .bas file you get an error.

I only have one View of yours (mea culpa ), I don't know what it is, I think I have downloaded it just to try to help someone. I added it that way (right-click = context) and had no problems.

I suppose (99%) that the context menu and "menu bar menu" are identical and at least operate in the same way. We could ask Erel, but I have never read any differences; as mentioned, I didn't even know that possibility existed (it's no more convenient than from the "top menu", I think).
