Detect animation finish in Android's RecyclerView

Question

The RecyclerView, unlike to ListView, doesn\'t have a simple way to set an empty view to it, so one has to manage it manually, making empty view vi

Answer 1

Here's a little Kotlin extension method that builds on the answer by nibarius.

fun RecyclerView.executeAfterAllAnimationsAreFinished(
    callback: (RecyclerView) -> Unit
) = post(
    object : Runnable {
        override fun run() {
            if (isAnimating) {
                // itemAnimator is guaranteed to be non-null after isAnimating() returned true
                itemAnimator!!.isRunning {
                    post(this)
                }
            } else {
                callback(this@executeAfterAllAnimationsAreFinished)
            }
        }
    }
)
