NOTE: Smoothie is currently just a draft API. Do not rely on it for production code. Feedback is very welcome.

What is it?

Easy async loading for Android's ListView/GridView.

Features

• Tiny API to implement asynchonous loading of items in Android's ListView and GridView.
• Tight integration between user interaction and async loading of items i.e. stops loading items on fling, enables loading when panning with finger down, etc.
• Prefetch items beyond the currently visible items to reduce the number of placeholder items while scrolling.

How do I use it?

1. Add Smoothie's jar as a dependency to your project.

2. Implement an ItemEngine. You're only required to implement two methods: loadItem() and displayItem().

3. On Activity/Fragment creation, attach a Smoothie instance to your ListView/GridView passing the target view and your engine:

   Smoothie smoothie = new Smoothie(yourListOrGridView, new YourItemEngine());

4. On your adapter's getView(), call Smoothie's loadItem() passing the item view and the loading parameters necessary to load the item asynchronously.

Here's a list of pending stuff on the library:

• Proper prefetch support with a custom priority queue on ItemLoader's executor service.
