for me this works fine:

iListBox = new( ELeave ) CAknSingleStyleListBox();
iListBox->ConstructL( this, EAknListBoxSelectionList);
iListBox->CreateScrollBarFrameL(ETrue);

//add the items to the list

iAvkonAppUi->AddToStackL(iListBox);

iListBox->ActivateL();
iListBox->DrawNow();
SetRect(aRect);
ActivateL();
//no need to call SizeChanged

Put SetEXtent in your SizeChanged function

eg:

void Csh_listAppView::SizeChanged()
{
list->SetExtent (TPoint(0,0), list->MinimumSize());
}

I am not doing anything in SizeChanged().i'l try to implement it now but i did try this also:

list->SetRect(aRect);

do v need to specify certain size as well?

What are you doing in the SizeChanged Method ? Are you calling SetRect on list box. You have to set the list box size before it becomes visible.
