Answer 1

This looks to be an elegant solution as well: http://benjii.me/2010/08/endless-scrolling-listview-in-android/

It also implements an AbsListView.OnScrollListener, and uses an AsyncTask to load more content as soon as a certain threshold of remaining items in the current scroll view is reached.

Ok i have seen that this is a common problem, so i have made a SMALL LIBRARY with custom load more and pull to refresh ListView in github, please check this at here, all is very explained in the repository.

Answer 3

You can implement an AbsListView.OnScrollListener, that gets informed and which allows you to load more data.

See e.g.

....
ListView.setOnScrollListener(this);
....

And then have a look at https://github.com/pilhuhn/ZwitscherA/blob/master/src/de/bsd/zwitscher/TweetListActivity.java#L287

Or take a look at the List9 example from the sdk examples.
