I know there were plenty of similar problems there but I didn't find specific problem like that. What I expect? After I update my row by setOnItemClickListener I want to update my listview from database and see it updated without screen moving to first row every time I update listview. How it works right now?

                    dbWorker.fillList();
                    ArrayList<Uni> List = StaticVariables.List;
                    final listviewAdapterList adapterList = new listviewAdapterList(ListActivity.this, List);
                    lvList.setAdapter(adapterList);

I know that I can somehow use notifyDataSetChanged() but I'm not quiet sure where should I use it to not move list from row I clicked to first row.

Do not create a new adapter to begin with. Just update the list for the adapter. (The data set). Then call notifyDatasetChanged. – blackapps Apr 07 '23 at 09:41
@blackapps So it should look like that: dbworker.fillList() than list = StaticVariables.List, than adapterList.notifydatasetchanged and thats all? – JohnBaron Apr 07 '23 at 09:55
If 'list' is the data set of the adapter then yes. But i think it's not. I dont know. – blackapps Apr 07 '23 at 10:29

Also you can remember and restore first visible item of the list view. – blackapps Apr 07 '23 at 10:36
