RecyclerView Adapter for RxJava, separates list's model from Android framework dependencies

Download Maven Central


Supports RxJava2 and automatic adapter notify dispatching (via DiffUtils comparison)


First, import the library via gradle dependency

compile 'sk.teamsoft:observablecollection:{latest_version}'

Check Sample app for both simple and advanced use-cases.

Simple case

  1. Create source (here, Data is the model class)
val source = SimpleAdapterSource<Data>(emptyList(), R.layout.view_data)
  1. Create Adapter and set to RecyclerView
recyclerView.adapter = ObservableAdapter(source)
  1. Prepare View
<sk.teamsoft.observableadapterdemo.simple.DataView ...>
    <TextView android:id="@+id/data" .../>
class DataView @JvmOverloads constructor(
    context: Context,
    attrs: AttributeSet? = null,
    defStyleAttr: Int = 0
) : LinearLayout(context, attrs, defStyleAttr), BindableView<Data> {

    private val label: TextView by lazy { findViewById( }
    private val detail: TextView by lazy { findViewById( }

    override val observableEvent: Observable<Any>?
        get() = RxView.clicks(this)

    override fun bindTo(item: Data) {
        label.text = item.label
        detail.text = item.detail
  1. Set data = listOf(data1, data2, data3)
