Android Question xCustomListView get Panel id

Declan · May 3, 2020

I am using this example:

[B4X] [XUI] Expandable list based on xCustomListView

Edit: Better to use CLVExpandable class: https://www.b4x.com/android/forum/threads/b4x-clvexpandable-allows-expanding-or-collapsing-xcustomlistview-items.106148/ Compatible with B4A, B4J and B4i. This example uses a slightly modified version of xCustomListView to create an expandable...

www.b4x.com

I have changed the name of the 2 X Buttons.
What I need to achieve is to read the Panel Id when one of the two Buttons are Clicked
Then action the Button function to Accept or Reject - On Reject, I must delete the item from the list
I have tried the following to get panel id:

B4X:

Sub btnAccept_Click
    Dim v As Button
    v = Sender
    Dim MyIndex As Int
    Dim MyIndex = clv1.GetPanel(v)
    LogColor("Button Accept: " & MyIndex, Colors.blue)
End Sub

How do I read the lblTitle.text of a panel on the Button_Click event
I always get :Item# 20" - the last item in the CustomListView, not the Item that I Clicked

@LucasM - Thanks
However, when I run:

B4X:

Sub btnAccept_Click
    Dim v As Button
    v = Sender
    Dim Index As Int = clv1.GetItemFromView(Sender)
    Dim pnl As Panel = clv1.GetPanel(Index)
    Dim MyIndex  As String = Index
    Dim MyPanel As String = pnl

    LogColor("Button Accept: " & v.text & "Index: " & MyIndex & "Text; " & "Panel: " & MyPanel & "Text; " & lblTitle.text, Colors.blue)
    CollapseItem(MyExpandedID)

It always returns "Item #20" and not the actual Panel Title text that the Button is in:

B4X:

Button Accept: AcceptIndex: 1Text; Panel: (BALayout): Left=0, Top=0, Width=1080, Height=420, Tag=trueText; Item #20

The best option is to store all the information you need in the Value object. Not in any UI element.

Sorry, I don't understand

Please upload a small project with the list.

Declan · May 4, 2020

The attached project is an edited version of the example in post 1.
In my main project, I am using Firebase notifications.
The "Title" and "Body" of the Firebase notification message is comma delimited and includes a unique ID.
When the Firebase message is received, it is loaded into the CustomListView and the user has the option to Accept or Reject the notification (btnAccept / btnReject)
If the user clicks btnAccept, I parse the notification string and write to SQLite table. Therefore, I must be able to read the full Text in the CustomListView
If the user clicks btnReject, I simply remove the CustomListView item.
I hope this makes sense

I'm sorry but I missed the fact that you are using an old and deprecated solution. There is a reason why it says:

Remove CustomListView class. Add CLVExpanded and xCustomListView library.

Ok, Done
Result is the same
Latest project with CLVExpanded and xCustomListView library.

That's expected.
lblTitle will point to the last one that was added.

I wanted to show you how to fix the code however I can't as you haven't implemented CLVExpandable correctly.

[B4X] CLVExpandable - Allows expanding or collapsing xCustomListView items

This class replaces the custom CustomListView module (https://www.b4x.com/android/forum/threads/b4x-xui-expandable-list-based-on-xcustomlistview.86449/). It works with the standard xCustomListView library. It is compatible with B4A, B4i and B4J. Instructions: An expandable item layout should...

Ok, Done.
The attached project runs.
btnReject_Click works and removes the item from the list

Were you able to solve the original problem?

1:

B4X:

For i = 1 To 20
        Dim Title As String = "Item #" & i
        Dim p As B4XView = CreateItem(Rnd(0xFF000000, 0xFFFFFFFF), Title, Rnd(100dip, 250dip) + 60dip)
        clv1.Add(p, expandable.CreateValue(p, Title))
    Next

2:

B4X:

Sub btnAccept_Click
    Dim Index As Int = clv1.GetItemFromView(Sender)
    Dim text As String = expandable.GetValue(Index)
    Log(text)
End Sub

If you need to store more information then use a custom type or array.

By the way: say a xCustomListview (CLV1) that contains a layout.pnl (p.LoadLayout("Items3") containing another xCustomListview (CLV2) that have a Checkbox (CHK1). All works as expected and a click on CHK1 is correctly fired. The question is: How may I read the status of CHK1 and the index of CLV1 and CLV2 of the CHK1 clicked?

You should never post questions in existing threads. There should only be a question in the very first post.
