B4J Question [ABMaterial] List like CustomListView

[yiankos1]

Hello,

I would like to create x number of custom items in a list, like we are doing in CLV. After that, when clicking a button/label/etc... onClick method is called and through Sender object you can get the specific child of that CLV.

I saw the example of infinite page that fits most like a CLV, but i can't figure out how to handle the onClick method of a random card's button.

Is there something that i am missing? or is there any other control/helper that fits more like a CLV?

Thank you for your time.

See my thread:
https://www.b4x.com/android/forum/threads/abmaterial-universal-page-for-application-settings.131563/

I'm building a MAP site, but to the point.
Each item on the list page has a different 'id' built from a parameter: this can be the idx of the database.
E.g. for checkbox

                        Dim input2 As ABMCheckbox
                        Dim split() As String = Regex.Split("=",linie.Get(i+1))
                        input2.Initialize(page, "inpCheck_"&split(0), s0, False,"")
                        If split(1)="1" Then
                            input2.State=True
                        Else
                            input2.State = False
                        End If
                        page.Cell(row,1).AddComponent(input2)

In the function that handles appearing events on the page
'Sub Page_ParseEvent(Params As Map)'.
I have support for ABMCheckbox

    If eventName.StartsWith("inpcheck") And eventName.Contains("clicked") Then
        objekt=""
        Dim split() As String = Regex.Split("_", eventName)
        If split.Length > 2 Then
            For i=1 To split.Length-2
                objekt=objekt&"_"& split(i)
            Next
            objekt = objekt.SubString2(1,objekt.Length)
            eventName = split(0)&"_"&split(split.Length-1)
        Else
            objekt = split(1)
            eventName = split(0)&"_"&split(2)
        End If
    End If

The way it works is that it pulls from id_paramater, the parameter itself, sets it to a global variable and then calls the ABMCheckbox handler functions

Sub inpcheck_Clicked(Target As String)
    Dim check As ABMCheckbox = page.Component("inpcheck_"&objekt)
    If check.State Then
        ChangeConfig(objekt, "1")
    Else
        ChangeConfig(objekt, "0")
    End If
    LogDebug("check - "&objekt&" "&check.State)
End Sub

In this way, you can handle any large ABMList list on the page elements within it.

Thank you very much for your answer.

I have to admit that it is a very clever approach!

Tomorrow, I will give it a try and I am gonna hit that 'Mark as solution' button.

Thanks again.

You can also use AddArrayComponent. Give every button an numeric id (like "1", "2", "3" etc...). Add them to the cell using AddArrayComponent(btn, "buttonName")

Here is an example of its usage (but with chips): https://www.b4x.com/android/forum/threads/abmaterial-addarraycomponent-simple-example.69213/#content

@MichalK73 & @alwaysbusy Thank you very much for your answers. I will try them both in order to see what fits more at my needs.

Wish you a great Sunday!
