I repurposed the DebouncingOnClickListener from Butterknife to debounce clicks within a specified time, in addition to preventing clicks on multiple views.

To use, extend it and implement doOnClick.

DebouncingOnClickListener.kt

import android.view.View

/**
 * A [click listener][View.OnClickListener] that debounces multiple clicks posted in the
 * same frame and within a time frame. A click on one view disables all view for that frame and time
 * span.
 */
abstract class DebouncingOnClickListener : View.OnClickListener {

    final override fun onClick(v: View) {
        if (enabled && debounced) {
            enabled = false
            lastClickTime = System.currentTimeMillis()
            v.post(ENABLE_AGAIN)
            doClick(v)
        }
    }

    abstract fun doClick(v: View)

    companion object {
        private const val DEBOUNCE_TIME_MS: Long = 1000

        private var lastClickTime = 0L // initially zero so first click isn't debounced

        internal var enabled = true
        internal val debounced: Boolean
            get() = System.currentTimeMillis() - lastClickTime > DEBOUNCE_TIME_MS

        private val ENABLE_AGAIN = { enabled = true }
    }
}
