Android Question How to get value in CLVSwipe (Customlistview)

Tasyo28 · Sep 27, 2019

Hi,

Good day everyone.

Still understanding how CLVSwipe works, now I'm stuck how to get the stored value return by CLVSwipe.
Please see sample code

B4X:

Sub Swipe_ActionClicked (Index As Int, ActionText As String)
    Log($"Action clicked: ${Index}, ${ActionText}"$)
 
   'i want to get here the value of the map stored in Swipe.CreateItemValue value to assign them to variable

End Sub


Sub Daterecords
   Dim m as map
   Dim OrderHistVal as list
   Dim parser As JSONParser

   parser.Initialize(j.GetString)
   OrderHistVal = parser.NextArray
 
   For i = 1 To OrderHistVal.size - 1
            m = OrderHistVal.Get((i)
            order_id_val = m.Get("order_id")
       
            cs.Initialize.Color(Colors.Blue).Append(order_id_val).PopAll
       
            clv.AddTextItem(cs, Swipe.CreateItemValue(m, Array("Cancel")))
       
   
   Next
End Sub

I tried to get the value using clv.GetValue(index) but i dont know what command to use to get the value on it.

this is the sample output of clv.GetValue(index) inside Swipe_ActionClicked:

[Actions=(ArrayList) [Cancel], IsInitialized=true, IsSwiped=false,MaxSwipe=205, Open=false, Value=[IsInitialized=false, orderid=34]]

As the result of clv.GetValue(index) i can see the value of orderid=34 which is correct, but how to assign it and get it as variable using the Swipe_ActionClicked.

Thanks for helping.

    Dim mmap As Map = m.Value
    Log($"itemMap = ${mmap}"$)

    If ActionText = "Delete" Then

    Else If ActionText = "Do Something Else" Then

        Dim lbl As B4XView = p.GetView(0)
        lbl.Text = "Done!!!"
    End If

Hi DonManfred,

Thanks for reply, based in your example the value result is Value={Test=0,Test2=75} how to extract this values and assign them to variables.

example:
dim Test as int = 0
dim Test2 as int = 75

Please advise what command need to use.

If the result is a map, please, read about them:

https://www.b4x.com/android/help/collections.html#map

You could get the value with:
Test2 = mmap.Get("Test2")
or
Test2 = mmap.GetValueAt(1)

Thank you very much! (DonManfred & Jose)
Everything is working now. Long Life B4X!

just refresh the thread and look again over my code. I´ve changed it.

please don´t. You should not use GetValueAt
