FastAdapter
FastAdapter is a Kotlin library that lets you build RecyclerView adapters in Android with minimal boilerplate and maximum performance.
- •You need a scrolling list (RecyclerView) with complex item types and want to avoid writing repetitive ViewHolder code.
- •Your app requires fast UI updates (diffing, selections, click handling) without hand‑rolled adapters.
- •You want to integrate item extensions (drag‑&‑drop, swipe, expandable) quickly using the same adapter instance.
```kotlin
// Add a selectable, expandable item with a sub‑list in one call
val parent = SampleItem("Parent")
val child1 = SampleItem("Child 1")
val child2 = SampleItem("Child 2")
fastAdapter.itemAdapter.apply {
add(parent)
add(child1, parent) // add as child of parent
add(child2, parent)
setSelected(parent, true) // auto‑expand
}

FastAdapter is a large Kotlin project (~17k lines across 177 code files, plus 10 test files). It is a full software project: use it through its install path rather than reading it end to end. Last commit 6 months ago, Apache-2.0 license, has a test suite.
