CustomListView - A flexible list based on ScrollView

[peacemaker]

Where is the code to add the CustomListView?
(lbl can be a name for a label. edt should be better )

CustomListView is added just by the Designer (Private cv As CustomListView) and all other for the dynamical use is already shown in the code above.
Other work is by checking the checkboxes state:

Dim L As List
L.Initialize
For i = 0 To cv.GetSize - 1
    Dim pnl As Panel = cv.GetPanel(i)
    Dim chk As CheckBox = pnl.GetView(0)
    If chk.Checked Then
        L.Add(i)
    End If
Next

I used your routines in the attached project and it works.

Maybe your cv is not in the Activity?

Perfect, now I have the same problem in my project.

If the CustomListView is created inside the Activity_Create, there is no problems with GetItemFromView called in the TextChanged event of an EditText added to a custom item.
If it is created after the Activity_Create is completed (pressing a button, for example) the TextChanged event will raise during the creation of the CustomListView and GetItemFromView gets a null parent.

Setting the properties of the EditText after the addition of the "item panel" to the CLV, I get no errors.

My mistake. I forgot to mention that you need the latest Reflection library.

could you please give me a link to the documentation realated to your list class. Actually I am looking for a list view which can hold name and small picture of the person. something similar to contacts list

Can I set "SetElevation" to each list item? Can anyone share some idea to do that? I tried adding SetElevation to panel but did not worked. Any help?

 

[Erel]

It should work. Please start a new thread for this and post the code that is now working for you.

V1.20 was uploaded to the first post. This version includes better designer support (requires B4A v5.80).

How can i update items in panel?

For example: i have 300 items in clvMaster list and when apk start it fills 300 items in clvMaster using:

clvMaster.InsertAt(ScrolledChannel, CreateChannelListMaster(ScrolledChannel, clvMasterCh.AsView.Width, 167dip, Channels(ScrolledChannel,3), Channels(ScrolledChannel,2), EPGs(ScrolledChannel,0), EPGs(ScrolledChannel,1), EPGs(ScrolledChannel,2), EPGs(ScrolledChannel,3)), 167dip, ScrolledChannel)

That works great...i have the following labels in each panel:

'UPDATE - EPG
lblEPGName.Text  = EPGs(ScrolledChannel,0)
lblEPGStart.Text = EPGs(ScrolledChannel,1).SubString2(11, 16)
lblEPGStop.Text  = EPGs(ScrolledChannel,2).SubString2(11, 16)
lblEPGDesc.Text  = EPGs(ScrolledChannel,3)

I have tried using removeitemat and insertitem at but i have duplicate panels, and would like to avoid this...can be added in this excellent class function:

Sub UpdateItemsAtPanel(Index As Int, Pnl As Panel, ItemHeight As Int, Value As Object, lblEPGName, lblEPGStart, lblEPGStop, lblEPGDesc As String)
   'UPDATE - EPG
   panel(index).lblEPGName.Text  = lblEPGName
   panel(index).lblEPGStart.Text   = lblEPGStart
   panel(index).lblEPGStop.Text    = lblEPGStart
   panel(index).lblEPGDesc.Text    = lblEPGDesc
End Sub

So the idea is to not remove existing panels in list witch is generated at apk start, only to update labels in existing panels at index....can erel or someone posto here code how to do that with this excellent class?

how can i download version prior to b4a 5.8?

 

[Erel]

This is not the correct place for this question.

 

[jazzzzzzz]

This is not the correct place for this question.

Am not asking about buying 5.8 ,am asking about the library version (customlistview) that support below 5.8 IDE

 

[Erel]

I see. V1.10 is attached.

which is the right way to set the item height?
I tried this:
change from original 100dip item height to 200dip itemheight when the user click the item
but I get an error

Sub clv2_ItemClick(Index As Int, Value As Object)
    Dim pnlnew As Panel
    Dim newvalue As Object
    newvalue = Value
    pnlnew= clv2.GetPanel(Index)
    clv2.RemoveAt(Index)
    clv2.InsertAt(Index,pnlnew,200dip,newvalue)
    Log(Index & " = " & Value)
End Sub

then I tried this and it worked:

Sub clv2_ItemClick(Index As Int, Value As Object)
    Dim newvalue As Object
    newvalue = Value
    pnlnew= clv2.GetPanel(Index)
    clv2.RemoveAt(Index)
    clv2.InsertAt(Index,CreateListItem($"Item #${Index+1}"$, clv2.AsView.Width, 100dip),200dip,newvalue)
    Log(Index & " = " & Value)
End Sub

Is there a way to only change the item height without deleting and adding the same item?

Please start a new thread for this in the questions forum and post the error message you got with the first code snippet.

Hi,

I can work with array of clv?
When I try to add a panel in the CLV(2) I have the Sub Asview error:
java.lang.NullPointerException: Attempt to read from field 'int android.view.ViewGroup$LayoutParams.width' on a null object reference

I can know the CLV panel position with the method javaobject?
similar to jo.RunMethod("getFirstVisiblePosition", Null) for listview.

thanks
