RecyclerView List Adapter for Kotlin

RecyclerViewListAdapter is a tiny Kotlin library that makes the creation of a simple RecyclerView Adapter, its ViewHolders, and their Views as easy as possible.

Usage

In order to create a RecyclerViewListAdapter, you need to supply a function that creates a View or a View subclass, and another function that takes a View or View subclass and an Item and updates that View.

One line example

val listAdapter = RecyclerViewListAdapter.create({ MyListItemView() }, {view, item -> view.update(item)})

Larger example

class MyListItemView(context: Context): LinearLayout(context) {

    val title: TextView

    init {
        title = TextView(context)
        addView(title)
    }

    fun update(title: String) {
        this.title.text = title
    }
}

class MyBiggerView(context: Context): LinearLayout(context) {
    val listAdapter: RecyclerViewListAdapter<MyListItemView, String>
    
    init {
        val createView = fun(): MyListItemView {
            return MyListItemView()
        }
        
        val updateView = fun(view: MyListItemView, item: String) {
            view.update(item)
        }
        
        listAdapter = RecyclerViewListAdapter.create(createView, updateView)
        val recyclerView = RecyclerView(context)
        recyclerView.layoutManager = LinearLayoutManager(context)
        recyclerView.adapter = listAdapter
        addView(recyclerView)
    }
}
