nestedList.Initialize(Activity)
nestedList.base.LoadLayout("CentralLayout")
nestedList.CLV = mainCustomListView
Drawer.Initialize(Me, "Drawer", Activity, 300dip)
Drawer.CenterPanel.LoadLayout("CentralLayout") 'here is based mainCustomListView, in this layout it must be nestedList
Drawer.LeftPanel.LoadLayout("DrawerLayout")
It will not work. The way to solve it is to combine B4XDrawer feature with CLVNested feature. Not so simple as the touch handling is quite complicated.
