Using   Set the head of the list to it bottom lv setStackFromBottom true    Worked for me and the list is scrolled to the bottom automatically when it is first brought into visibility  The list then scrolls as it should with TRANSCRIPT MODE ALWAYS SCROLL

You need to use these parameters in your list view    Scroll lv setTranscriptMode ListView TRANSCRIPT MODE ALWAYS SCROLL   Set the head of the list to it bottom lv setStackFromBottom true     You can also set these parameters in XML  eg  like this    lt ListView           android transcriptMode  alwaysScroll     android stackFromBottom  true    gt

Supposing you know when the list data has changed  you can manually tell the list to scroll to the bottom by setting the list selection to the last row   Something like   private void scrollMyListViewToBottom         myListView post new Runnable              Override         public void run                    Select the last row so it will scroll into view                myListView setSelection myListAdapter getCount   - 1

A combination of TRANSCRIPT MODE ALWAYS SCROLL and setSelection made it work for me  ChatAdapter adapter   new ChatAdapter this    ListView lv    ListView  findViewById R id chatList   lv setTranscriptMode AbsListView TRANSCRIPT MODE ALWAYS SCROLL   lv setAdapter adapter    adapter registerDataSetObserver new DataSetObserver          Override     public void onChanged             super onChanged            lv setSelection adapter getCount   - 1

The transcript mode is what you want and is used by Google Talk and the SMS MMS application  Are you correctly calling notifyDatasetChanged   on your adapter when you add items
