B4A Library [Lib] UltimateListView

I've been working on this project for a long time and I'm very proud to release the version 4 today.

The UltimateListView is, as its pompous name says, THE ListView.

• It can handle very long lists. This is a screenshot of a list with 245813 items, all different:
  
  
  
  
  
  
• It can mix different layouts (and they can be changed dynamically). You can use it as an expandable ListView:
  
  
  
  
  
  
• It has a low memory footprint and is very fast (this report comes from the Performance demo where the list has to display 128901 distinct words read from a database and the used device is a Huawei Honor single core 1.4 Ghz):
  
  
  
  
  
  
• It can scroll in both directions thanks to its swipe detector:
  
  
  
  
  
  
• The swipe detector can also be used to implement a swipe-to-dismiss or a swipe-to-reveal:
  
  
  
• You can easily add editors to your table to change its content:
  
  
  
  
  
  
• You can animate the items when they are added, removed, replaced or when the list is scrolled (with your own custom animation):
  
  
  
  
  
  
• It can stack items from the bottom:
  
  
  
  
  
  
• It supports drag & drop operations (internal & external):
  
  
  
  
  
  
• You can synchronize lists with different item heights:
  
  
  

The examples will show you how to implement a Pull-to-Refresh, create sticky headers or combine several lists to make a wheel. One of the examples is an improved version of my File Explorer class.

All texts and images can be loaded asynchronously (from Internet, from a database or from a local folder), so you can scroll even if the data are not fully loaded.

The list has its own state manager.

Since September 2018, ULV is available for free. You can still donate for it if you wish.
To send the money, just click on the Donate button below (the amount to enter is in euros):


Note that UltimateListView is not a wrapper around the work of someone else. It is 100% my own code and it is based upon the standard Java ListView of Android.

The UltimateListView does not work with Android versions < 2. It cannot work with B4J or B4i.

Current version: 4.50

good day Informatix,

i just donated for ULV just now.
thank you.

 

[Juanjo Martínez]

I have just made mine, sorry I forget to indicate ULV

I've just converted another of my apps from clsChecklist to ULV, and the drag-and-drop is much nicer now.

One suggestion: When dragging an item within the list (internal), the item inserts itself into the list while I'm still dragging, which initially confused me. (I was trying to see which item I was on top of, and discovered it was the one I was dragging.) I think it may be clearer (and closer to other implementations I've used) if the target space was left blank during the drag (or perhaps an option for this, if it is indeed a personal-preference type of thing).

Cheers!

You have already a full control on what's displayed (look at "If DraggedID = ItemID Then" in the demo; set everything to blank if you want an empty item).

 

[Dave O]

Ah yes, I thought that only changed the appearance of the dragged item (on top), but it actually affects the dragged item in the list itself.

I added a masking panel of the same color as the item background, and made it visible in the ContentFiller event if it was the dragged panel. It's now easier to see where I'm dropping the panel.

Works great, thanks!

You can also set Visible to false for the contents.

 

[Dave O]

You can also set Visible to false for the contents.

I considered that, but a single panel is easier to manage when there are several elements in the layout, and I may add more in future.

I'm not sure that I understand because ULV is fundamentally a listview. So why should it include such a feature?
If you want that, you can use a dedicated view like TouchImageView.

 

[Andris]

Informatix, does UltimateListView have any collapsible feature?

 

[Informatix]

Yes.
