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

Hi all. I have this ULV with editText that i can fill in runtime, so after that customer insert example:
aaaa
bbbb
cccc

is possible reading this edittext ?

Dim totale As Int =    ulv.NumberOfItems
    For i = 0 To totale
        ???
    Next

Thank you

You should have a reference to this data already as that's how you will populate the views contained in ULV. Do you not have a List object (perhaps in Globals) where you hold the values?

I explain better.
These data will be entered by the user at runtime, so I can not know before values.
The same are inserted empty, initially, it will be filled out by the user at a later time. I would have only one cycle (or other) where you can select the user submitted values

When the user has finished entering these values, where do you store it? I'd imagine you will have a data structure (custom type) and have a list of these objects stored in memory or perhaps you commit them to the DB? In either case, you have a 'store' where you get the values from and that's what I was referring to above.

Is sufficient map.
But how do get the value ?

 

[shashkiranr]

If possible, use something like the below code. Store the output corresponding to each edittext in a map. Call this sub from every edittext_textchanged sub.

Sub StoreInput(EditTextTag as String, input as String)
       Select EditTextTag
            case "et1"
                In_Some_Map = input
            case "et2"
                In_Some_Map = input
       End Select
End Sub

Best,

Hello,

Is it possible to achieve this with ULV?

You can create a grid as the example shown above, but not two columns with different heights for each column. The PinterestListView uses in fact two listviews that are synchronized when scrolling. I will look at how they are synchronized to see if I can reproduce that easily with ULV.

I downloaded the latest version, but the bookstore did not come datacollection library

It's a separate download. There are two links in your email.
This library has no update for now.

Hello
a question
UltimateListview believe that interest to all,
SetActivityAttribute (Main, Android: hardwareAccelerated, "true") is recommended for every activity that has UltmateListView?
Thank you

Hello

SetActivityAttribute (Main, Android: hardwareAccelerated, "true") is recommended for every activity that has UltmateListView?
Thank you

Yes and no. No because hardware acceleration requires more RAM and is useless in most cases, and yes because you may benefit from the acceleration depending on what you put in your item. As a general rule of thumb, the best thing is to try. If this setting improves things when True, keep it.
