B4A Library [Lib] UltimateListView

Informatix · Oct 26, 2012

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

Is that possible, to make a modern chatlayout with the ULV?

Yes it is, look this:

This is to demonstrate, what is possible, with the ULV

You have no idea what's possible with ULV... (and B4A)
Have a look at what I'm building...

You can give me tips so that my solution will be as good as yours

Informatix · Jun 30, 2017

I'm out from 01/07 to 12/07. So I won't be able to send links and answer to questions during this period.

Ok, leave us your phone number so we can contact you while you are on vacation

Obviously I am joking

Have fun

What about integrating the Native Ads In the ULV, It is possible?

Something like WPS does

I never studied the question but I know that people successfully embedded ads in their ULV so you could discuss here of the method.

Download it. The link and password do not change.

Link is dead.. I'm stuck on version 4.00. Could you send me the new version? (I also read about the gift of sending another bookstore for who bought it)

that should not be a problem. you just add the adview to a panel inside the ulv item.

just note that admob does not allow showing banners like this!

Hello,

You have two examples demonstrating this: Demo_DBTable (small database) and Demo_WordDBTable (huge database). The right solution depends on the size of your SQLite database.
When you edit a cell, send the changes to the database with an update query.

Hi
There 47 pages here, where can I find the 2 DB Demo's. Also when you first released this i'm sure that there was some kind of demo displaying the different types of lists, is that still available

It's in my signature ("the catalog..."). It's a bit outdated.

Thanks for the replies
Can I ask a couple of questions before I purchase
1. If I want TAB pages do I use the standard B4A Tabs or does ULV have a Tab pages method.
2.Can I display a Master record (like an Invoice Header) followed by detail Line Items, then Master and detail again etc. Obviously the detail has a different layout and size (depth) than the Master. Would that be like your Sections Demo - if so can you have multiple lines in the 1st (header) Line (Countries in your example)
3. Can they scroll both vertically and horizontally

Apologizes if these question have been answered in the previous 47 pages - I started to go thru them but so much was detail and irrelevant to me
