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

another question... can I have 2 ULV and drag and drop items from first to second? and can I have items with inner ULV and drag and drop from first to inner and from second to inner and viceversa?

Yes, you can exchange items between ULV. Declare the other ULV as a DropView in StartDrag and handle the Dropped event to insert a new item in the target.
What do you mean by "inner ULV" ?

1 - Drag and drop from ULV 1 item to ULV 2
2 - Drag and drop from ULV 1 item to Inner horizontal ULV (into ULV 2 item)
3 - Drag and drop from ULV 2 item to Inner horizontal ULV (into another ULV 2 item)

oh! and naturally, reorder ULV 2 items with drag and drop also...

are these possible?

thanks in advance

To create an item that scrolls horizontally, place an HorizontalSlaveView (provided with the latest version) or an HorizontalScrollView in your item.

it's a problem because i need items reorder into horizontal list (drag and drop internal and extenrnal)... like ULV behavior...

Hi

How can i capture a click event in a button inside a panel of ULV ?

The same way you capture it for any button. When you add the button and initialize it just add the eventname.

You dont understand, i need to associate another info on the same row with a button click event. For example, use a edit text value in the click event of the button.

You will have to store a reference to the edit text somewhere so you can retrieve the information. For e.g. you can store the edit text as the tag object of the button.

I got so sick that I'm just barely able to write this. Sorry but you'll have to do without me for a few days.

Sorry to hear that. Hope you get better soon.

Hi,

I sent in a donation of 25 Euros.

I look forward to using the UltimateListView.

 

[rleiman]

Hi Everyone,

Can you tell me how long it normally takes for you to get the files for the UltimateListView?

I sent in a donation last night but have not seen any response in either my inbox or the spam folder.

I think I will also send an email to the developer. I look forward to learning how to use the UltimateListView.

In the last update informatix included the following:

"It's time for me to enjoy my holidays in another country, far from a computer, so don't expect any answer before 2014."

Normally within the same day.
But he is gone on vacation and will return in 2014.

 

[rleiman]

Hi,

Thanks for the quick reply.

I'm attaching proof of the donation sent to Informatix, could I get a copy of the files you have so I can start using the UltimateListView?

I normally don't ask such a question but I'm really excited about using it and don't want to wait almost 2 weeks.

Does any know if you can overwrite a UltimateListView entry ?
