B4A Library [B4X] [XUI] xCustomListView - cross platform CustomListView

JLS · Nov 9, 2017

That works!

Thank you very much.

The attached project is a B4A project. To run xCustomListView on iOS device I can import the code and the class (as it is) within a B4i project?

Erel · Nov 14, 2017

Add the class as-is to your B4i project. The code in the main module will require some small changes.

In post #14, I asked if one could put EditTexts in the xCustomListView.
In fact, you can

I have added rows of "items" into the clv that contain panels which contain a label and an EditText view.
It is important to my application that when the EditText gains/loses focus that I suppress the soft keyboard with IME and then show my own custom keyboard.
When the EditText is touched the FIRST time, this works great

If you exit the EditText (change focus to something else), the custom keyboard disappears as appropriate, but when you touch the same EditText to regain focus, the Focus Changed event does NOT fire...
However, the soft keyboard does pop-up...
When you touch the soft keyboard, the Focus Changed event then DOES fire...
Am I doing something wrong? When I load the CLV, I load a .bal file with the EditText defined within...
Any ideas are welcome...
Rusty

UPDATE: The Focus Changed event does not fire when you touch the soft keyboard, it is the TextChanged event...
FURTHER UPDATE: I updated Erel's example and placed an edittext within the .Bal file. It generated the CLV with the label, button, chechbox and edittext views as planned.
When I touch the edittext, the hasfocus fires. If i touch any other edittext, the hasfocus fires, if i touch a button, checkbox or label, the hasfocus does NOT fire.
Is there a way to make the focus change when another type view is touched?

Hi @Erel

Can I request for the next version ?
At _ReachEnd event, can be added ProgressBar at the bottom like PullToRefresh like example here
Thank you

Erel · Dec 27, 2017

My CLV's are created in run time

How can I solve it?

Erel · Dec 31, 2017

xCustomListView as well as the latest versions of CLV must be added with the designer. You can create a layout file with only a CLV and load it whenever you want to create one.

Dadaista · Dec 31, 2017

Hi!!

Ok Erel

Thx!!

Hi All
I have downloaded the project attached to post #1 (v1.20)
It compiles and runs with no problems.
But when i add a new layout to the project, I get the following error when calling 'Activity.LoadLayout("2")'
java.lang.RuntimeException: java.lang.RuntimeException: CustomView CustomType property was not set.
(I did search the forum, but did not find any solution)
In the designer the Custom type property is greyed out, so it is not possible to change it.

Starting a new project does not help.

Biggest problem is that an existing project where I use CustomListView v1.76 suddenly have the exact same problem.

B4A - 7.80
JDK - 8.152
Android 27

Latest info !!
Downgraded to B4A 7.30 - Problem solved

!!!! or

...

Latest-Latest info !!
7.30 -

7,80 -

In the designer when I select 'Add View' the arrow next to CustomView is missing in B4A 7.80

Erel · Jan 2, 2018

Please start a new thread in the questions forum and upload the project that fails to compile.

Make sure not to confuse between:
1. This class.
2. The old CustomListView class.
3. CustomListView library.

XbNnX_507 · Jan 8, 2018

is it possible to use VisibleRangeChanged event to reuse the views in runtime instead of creating and removing these?
( similar to the way recycle view works).

Hi All,
I'm trying to use a CLV with horizontal scrolling with no success, i set it as the tutorial:
Dim p As B4XView = xui.CreatePanel("")
p.SetLayoutAnimated(0,0,0,180dip,CLVMap.AsView.Height)
CLVMap.Add(p, cd)
But i'm still getting items added vertically, any help would be appreciated.

EDIT:
LOL i didn't see it "set it in the designer", ROFLCOPTER, i'm sorry

Thanks!

Hi Erel,
At video time 2:17 I noticed that class version is 1.51, but the one attached to the first post is still 1.50.
Are there changes coming?

Erel · Feb 25, 2018

V1.51 was uploaded now.

Claudio Oliveira · Feb 26, 2018

@Erel ,
Apparently there's a mistake in RemoveAt sub.
When there are text items in the list, RemoveAt sub calculates NewOffset values incorrectly.

This code line

B4X:

Dim NewOffset As Int = item.Offset - item.Size - DividerSize

Should be like this

B4X:

Dim NewOffset As Int = item.Offset - RemoveItem.Size - DividerSize

Regards
