OverScrollListView is a drop-in replacement for ListView.
The OverScrollListView class implements the bounce effect & pull-to-refresh feature for ListView(this implementation can also be applied to ExpandableListView).
This pull-to-refresh implementation is inspired by XListView with the idea of adjusting height of the header view while pulling the ListView.
For the bounce effect, it simply intercepts touch events and detects if the scrolling has reached the top or bottom edge, if so, we call scrollTo() to scroll the entire the ListView off the screen, and then with a Scroller, we compute the Y scroll positions and create a smooth bounce effect.
For pull-to-refresh, it uses a header view which implements the PullToRefreshCallback interface as the indicator view for displaying "Pull to refresh", "Release to refresh", "Loading..." and an arrow image. Of course, you can implement PullToRefreshCallback and write your own PullToRefreshHeaderView, as long as you follow requirements for the layout of the header view, take the default PullToRefreshHeaderView as a referenece.
NOTE: If you do not want the pull-to-refresh feature, you can still use OverScrollListView, in that case, OverScrollListView only offers you the bounce effect, and that is why it has the name. Just remember not to call setPullToRefreshHeaderView().
- v1.1.0 - Added OverScrollListView.finishRefreshingAndHideHeaderViewWithoutAnimation(), which produces more desired effect when used in situations that needs to use "pull down & release" to load more, such as in a conversation ListView where we pull down & release to load the conversation history.
- v1.0.5 - Bugfixes
- v1.0.4 - Disabled by default the "pull to load more" feature, which must be manually enabled or disabled. Fixed a few bugs.
- v1.0.3 - Added support for "pull to load more" with a footer view.
- v1.0.2 - Rewrite the code for handling over-scroll, and some bugfixes.
- v1.0.1 - Some bugfixes.
