Android Question Error thrown in changing heights of clv items

[Oliver Simith]

Hi all,
I was trying to change the panel heights of CLV items, but the app crashed when loading.

Private Sub SetHeightsMaxOfItems(maxheight As Int)
    For i=0 To clv1.Size-1
        Private newPanel As B4XView=clv1.GetPanel(i)
        
        Private newItemValue As Object=clv1.GetValue(i)
        
        Private lblT As B4XView=newPanel.GetView(0)
        Private lblB As B4XView=newPanel.Getview(1)
        
        lblT.Height=maxheight
        lblB.Height=maxheight
        
        newPanel.Height=lblT.Top+lblT.Height+5dip 'change the height of the panel
        
        newPanel.RemoveViewFromParent
        clv1.RemoveAt(i)       
        
        clv1.InsertAt(i,newPanel,newItemValue) 'app crashed on this line
        Log($"item ${i} modified"$)
    Next
    
End Sub

I would like to know why this error happened and what is the right way to change a panel height.
Thank you very much.

Private newItemValue As Object=clv1.GetValue(i)

Is the item value a Pane(l)?

It can be done but it is quite unusual; are you sure?

 

[Oliver Simith]

The item value is not a panel, but an integer. Why did you think that is a panel?

My mistake in reading the source.

I'm just replying in case someone has the same problem.
After several days of testing, I finally found the cause of this error:
I forgot to use the panel.SetLayoutAnimatied() method, when I was adding Items to Clv, prioring to changing the panels' height. That mistake made the value of the CLVItem.size 0 and the app crashed somewhere that needs CLVItem.size as a parameter.
