android - How to scroll to the bottom of ListView programmatically?

Question

After calling notifydatasetchanged(); I want to scroll to the bottom of list so that user see the last record in the Listview.

(I am writing Chat module so for that purpose I need latest record at the bottom of list to be visible)

Can any one guide me how to achieve this?

I know that this has been answered and you took the answer and it was more than a year ago. But a better way to do this is Transcript Mode. For a demo, see the Android API Demo under Views > Lists > Transcript.

You would set the following on your list view in the XML.

android:stackFromBottom="true"
android:transcriptMode="alwaysScroll"

It will always work whenever you call notifyDataSetChanged(). You can set android:transcriptMode to normal instead if you want an even better result for chat applications: it will scroll to the bottom only if the last item was already in view. That way your users can view the previous chat without interruption when other users chat.

• transcript mode
• stack from bottom
