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

I have also a Moto G among my devices and I see no problem at all. Note that you give me each time a different line where the error happens and no steps to reproduce it so what can I think of it? So the case is closed until you provide me with a way to reproduce the issue.

Hi Frédéric, do you think about porting your library on B4i?
Thx

The new version (4.02) is online. The filename, the link and the password do not change, but the contents is new.
This version requires Java 7 (check your Tools/Configure Paths/javac.exe).

Changelog:
- The state of the fast scroller is now properly recognized under Lollipop;
- I fixed a bug with layout names in some languages;
- I added the GetRelativeIndexForID function;
- I brought minor improvements to examples.

Just donated my 24 Euros. Not sure when I'll use this library, but your efforts throughout the B4A community certainly deserve to be compensated.

Hello, Informatix

It seems that ULV is not fully compatible with StdViewPager from StdActionBar
I created StdViewPager with a few panels. Each of the panels contains it's own instance of ULV.
When I drag a panel, the new panel arriving on the screen doesn't show (during the movement) the ULV with data, just solid white surface.
When I take a finger away, ULV with data appear on the screen.
As far As I understand, there is kind of event, which View on the StdViewPager panel must handle to show something during the movement.

Could you check and correct it ?

I modified the Erel's example and I don't see any problem. Could you send me (by email) a project that shows the problem?
Theoretically, ULV should not exhibit an issue with Android standard libraries.

Thank you. I will investigate the example you provide and compare with my project to find the difference.

??? The answer is in your question. Set the corner radius of cd to 0 instead of 6dip.

Thanks.
Is only to change dip of code:

Dim cd As ColorDrawable
cd.Initialize(Colors.Blue, 0dip)

Very easy and I did not know how.
