Android Question CustomListView - RadioButton

[WebQuest]

Hi community I'm having problems with the configuration of a customlistview.
I added a layout in which there is a radiobutton, I can not cause the previous one to be disabled when the next radiobutton is clicked. Some idea?

Do you mean that in every single item there is only 1 Radio button?
In that case I think that it's a normal behaviour because every panel/item will work on it's own.
If you need to show that 1 item is selected above the others maybe you should use 1 checkbox in every item and make a cicle to disable all the others when 1 got selected.

I can suggest. (but I still rather new to the CustomListView object model. There is likely a better way, but I assume that in your code that "adds" the button to each row you have something like this:

   Dim p As     B4XView = xui.CreatePanel("")
   p.SetLayoutAnimated(0,0,0,100%x, 35dip)

    p.LoadLayout("GridRow")

    Label1.Text       = Crsr.GetString("ID")
    Label2.Text       = Crsr.GetString("HotelName")
    Label3.Text       = Crsr.GetString("City")
    Label4.Text       = Crsr.GetString("FirstName")
    RadioButton1.Checked = False
    RadioButton1.Tag = Crsr.GetString("ID")

    ViewData.Tag      = Crsr.GetString("ID")
    
   Return p

Now (even from designer), add a event for the radio button.

And, that code, you get this

Sub RadioButton1_CheckedChange(Checked As Boolean)
    Dim r As RadioButton = Sender
    Dim rRadioFromRow As RadioButton
    ' Log(r.Tag)    this gives the current row id.
    Dim i As Int
    For i = 0 To CustomListView1.Size - 1
        rRadioFromRow = CustomListView1.GetPanel(i).GetView(5)
        If rRadioFromRow.Tag <> r.Tag Then
            rRadioFromRow.Checked = False
        End If
    Next

Now, in above I had to "guess" which index the radio button is in the GetPanel. My spider sense tells me:
There is likely a better way to loop over each row.
There is likely a better way to get/grab/pull out the rRadioFromRow from the GetView.
However, the basic idea for above should work. I would hope the list is not too long.

And if anyone reading this?
Perhaps a for/each collection is available here? (I'm new to this).
So I not sure if above is the preferred way to loop over the custom list view.

However, while some kluge is in above? In theory the above idea is a means to do this. In above, for the tag setting I had a PK id from a data table, but anything from each row that can identify the separate row will work. (you could even use a loop counter in the panel add part).
I just don't know if a better means/way exists to figure out what index the radio button is in that "list".
So the 5 is a guess on my part - but it does work for me. You just have to figure out the index of the RadioButton in that single panel that you load for each row of the CustomListView.
