B4A Library [Lib] UltimateListView

Informatix said:

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:
  
  View attachment 18467
  
  
• It can mix different layouts (and they can be changed dynamically). You can use it as an expandable ListView:
  
  View attachment 14357
  
  
• 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):
  
  View attachment 21236
  
  
• It can scroll in both directions thanks to its swipe detector:
  
  View attachment 14361
  
  
• The swipe detector can also be used to implement a swipe-to-dismiss or a swipe-to-reveal:
  
  View attachment 21240

• You can easily add editors to your table to change its content:
  
  View attachment 14356
  
  
• You can animate the items when they are added, removed, replaced or when the list is scrolled (with your own custom animation):
  
  View attachment 21238
  
  
• It can stack items from the bottom:
  
  View attachment 16150
  
  
• It supports drag & drop operations (internal & external):
  
  View attachment 21235

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.

Due to the important work made, I request a minimum donation amount of 25 euros.

To send the money, just click on the Donate button below (the amount to enter is in euros).

What you'll get:
- the main library and all the libraries required by the examples;
- a complete User's Guide;
- a detailed list of all functions, events and properties;
- a tutorial;
- 16 examples with a few useful and reusable classes.

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.

You can download here the list of all functions and properties, and the table of contents of the user's guide.

With my catalog, you can try all examples of this library.

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

Current version: 4.10

Bonus : the DataCollection library is available for free with UltimateListView.

WHEN DONATING, PLEASE INDICATE CLEARLY IN THE PAYPAL FORM THAT YOU DONATE FOR ULV TO AVOID ANY CONFUSION WITH MY OTHER LIBRARIES.

Today use your library's performance is very good, but I think a custom layout, as I upload the picture effect, format, and is only allowed to select up to 9 pictures, I this how to do, whether given code, thank you，I have modified your "ClsExplorerForULV" code, but I can't really do what I want to do,

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!

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.
