Hi Moto, at this moment I'm working on my own custom ListView implementation so I can share some investigations I've found about ListView internals. 1) First of all ListView is adapter view that means that it uses adapter object to get it's child views - take a look at ArrayAdapter.getView(int, View, ViewGroup) 2) ListView at the moment only contains children that are on the screen. For example, if you have adapter with 100 records but only 5 are fit on screen ListView.getChildCount will return 5 not 100 3) each time you scroll your list it refresh dynamically its children list getting child view from adapter and/or relayouting existing views offsets
I dont have best understanding now but I think ListView state is : 1) first position of child view of screen 2) offset of child view within parent view if you know first position and it offset you can simply get from adapter and draw other ones android.widget.AdapterView.getFirstVisiblePosition() will give you a position of first item within adapter data on the screen use getChildCount() and getChildAt() of ListView to get current child views so you can obtain some layout details ListView.setSelection(int) allows you to sets the currently selected item but I think It will not scroll smoothly to it... Hope this will help you Thanks, Pavel On 27 апр, 03:05, Moto <medicalsou...@gmail.com> wrote: > I hope someone can shed some light? :( > > On Apr 25, 9:37 pm, Moto <medicalsou...@gmail.com> wrote: > > > > > > > I'm trying to figure out how it's been designed.
