# Pull To Refresh Views for Android  This project aims to provide a reusable Pull to Refresh widget for Android. It was originally based on Johan Nilsson's [library](https://github.com/johannilsson/android-pulltorefresh) (mainly for graphics, strings and animations), but these have been replaced since. ## Features * Supports both Pulling Down from the top, and Pulling Up from the bottom (or even both). * Animated Scrolling for all devices. * Over Scroll supports for devices on Android v2.3+. * Currently works with: * **ListView** * **ExpandableListView** * **GridView** * **WebView** * **ScrollView** * **HorizontalScrollView** * **ViewPager** * Integrated End of List Listener for use of detecting when the user has scrolled to the bottom. * Maven Support. * Indicators to show the user when a Pull-to-Refresh is available. * Support for **ListFragment**! * Lots of [Customisation](https://github.com/chrisbanes/Android-PullToRefresh/wiki/Customisation) options! Repository at <https://github.com/chrisbanes/Android-PullToRefresh>. ## Sample Application The sample application (the source is in the repository) has been published onto Google Play for easy access: [](http://play.google.com/store/apps/details?id=com.handmark.pulltorefresh.samples) ## Usage To begin using the library, please see the [Quick Start Guide](https://github.com/chrisbanes/Android-PullToRefresh/wiki/Quick-Start-Guide) page. ### Customisation Please see the [Customisation](https://github.com/chrisbanes/Android-PullToRefresh/wiki/Customisation) page for more information on how to change the behaviour and look of the View. ### Pull Up to Refresh By default this library is set to Pull Down to Refresh, but if you want to allow Pulling Up to Refresh then you can do so. You can even set the View to enable both Pulling Up and Pulling Down using the 'both' setting. See the [Customisation](https://github.com/chrisbanes/Android-PullToRefresh/wiki/Customisation) page for more information on how to set this. ## Apps Want to see which Apps are already using Android-PullToRefresh?
