Android Question How to change item text on xCustomListView?

[cenyu]

Hello,
I have one xCustomListView anl a small list of items witch i use to display some customer info:

    CLV1.Add(CreateListItem("Access type", CLV1.AsView.Width, 60dip), $"Item #${1}"$)
    CLV1.Add(CreateListItem("Access date", CLV1.AsView.Width, 60dip), $"Item #${2}"$)

When user click on CLV1 item and change this setting my CLV1 item have to change it's text according to user selection. Is it possible to change item text dinamicly by Item index?

I only find how to add item:

Private Sub CLV1_ItemClick (Index As Int, Value As Object)
    ToastMessageShow(Index,True)
    CLV1.InsertAtTextItem(Index,"JABA",Value)
End Sub

I found a solution. It's simle but works!

CLV1.InsertAtTextItem(Index,"JABA",Value)
CLV1.RemoveAt(Index)

It looks that your items are all AddTextItem, right?
In the case try this

CLV1.GetPanel(index).GetView(0).Text = "NEW TEXT HERE"

The code you have in post #2 does not look correct. The lines should be reversed. It should be:

clv1.RemoveAt(Index)    
clv1.InsertAtTextItem(Index,"JABA",Value)

The solution that @Sagenut gave you in post #3 works too.

You are right! Thank you!

.GetPanel(0)?
I have no panel...

 

[Sagenut]

.GetPanel(0)?
I have no panel...

Every CLV item is basically a Panel and it's needed to reference the one (using the Index) that you want to access to work on it.

But when try this code i receive "Object have to be initialized first" error.

 

[Sagenut]

We should see your code to better understand.
Today I am unable to send you an example.
I can do it tomorrow, if someone does not help you earlier.

Here is my code:

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.
    Private xui As XUI
End Sub

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    Private CLV1 As CustomListView
End Sub

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("Layout")
    CLV1.Add(CreateListItem("Access type", CLV1.AsView.Width, 60dip), "AccessType")
    CLV1.Add(CreateListItem("Access date", CLV1.AsView.Width, 60dip), "StartDate")
End Sub

Sub Activity_Resume

End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub


Sub CreateListItem(Text As String, Width As Int, Height As Int) As Panel
    Dim p As B4XView = xui.CreatePanel("")
    p.SetLayoutAnimated(0, 0, 0, Width, Height)
    p.LoadLayout("CellItem")
    Return p
End Sub


Private Sub CLV1_ItemClick (Index As Int, Value As Object)
    ToastMessageShow(Index,True)
'    CLV1.RemoveAt(Index)
'    CLV1.InsertAtTextItem(Index,"JABA",Value)
   
    CLV1.GetPanel(0).GetView(Index).Text = "NEW TEXT HERE"
   
End Sub

Into layout CellItem i have one label and button...

And thanks for your time! I appreciate your help, Sagenut!

nd thanks for your time! I appreciate your help

You need to get the index of the panel not the index of the label, and then inside that panel is the firt label at position 0 referred to as GetView(0)
This line:

CLV1.GetPanel(0).GetView(Index).Text = "NEW TEXT HERE"

Should be like below:

CLV1.GetPanel(index).GetView(0).Text = "NEW TEXT HERE"
