Android Question CustomListView and sv.ScrollViewInnerPanel [Solved]

Hi All

I am trying to ensure the ScrollViewInnerPanel aligns with scrollview in CLV.
I don't even know if aligning is possible/needed I am just speculating that this may the cause of a small problem. It looks simple enough.

I have tried the code below but it throws the error shown.

B4X: 
    CLV.GetBase.Height = 100%y - LBLTitle.Height      'Set height of CLV
    CLV.GetBase.Top = LBLTitle.Height                         'Set position of CLV on Activity/Panel

    CLV.sv.Height =CLV.GetBase.Height                      'Set sv to same height as CLV
    CLV.sv.Top = CLV.getbase.Top                               'Align top of sv with top of CLV

    CLV.sv.ScrollViewInnerPanel.Top = CLV.sv.Top       'Should align top of ScrollViewInnerPanel with top of sv but crashes

The last line of the code above causes the error shown below.


Q1. Is it possible to align sv with ScrollViewInnerPanel? If not I will try something else.
Q2. What am I doing wrong?

Regards Roger

What exactly do you want to achieve, align?
Why do you want to set ScrollViewInnerPanel.Top?

Klaus,

I had an issue where a CLV was showing a list with an overly large space between the Title Label and the first item.
I was clutching at straws with the speculation that this could be caused by the ScrollViewInnerPanel sitting low in the sv. [Wrong]

I have fixed that problem with the change in code below. Comment out the lines that should align the sv with the CLV and the problem is gone.

B4X: 
    AllListView.GetBase.Height = 100%y - AllListTitle.Height
    AllListView.GetBase.Top = AllListTitle.Height
   
'    AllListView.sv.Height = AllListView.GetBase.Height                           ''With these two lines removed all OK
'    AllListView.sv.Top = AllListView.getbase.Top

I am still chasing an issue that only 5 of the items are displayed although there is screen space and the CLV dimensioned to use it.
I can't recreate the issue in a small project for upload.
That is a separate problem for a new thread if I can recreate the problem in a sample project.

Regards Roger

PS Change the two lines in question fixes it all round.
B4X: 
AllListView.sv.Height = AllListView.GetBase.Height
AllListView.sv.Top = 0
