Answer 1

You may employ RxAndroid in that case in Kotlin it shall be like this:

yourView.clicks().buffer(500, TimeUnit.MILLISECONDS, 2).filter {
    it.size >= 2
}.subscribe {
    // Handle double click
}

1. We apply clicks() extension function on a given view which creates an RX observable sequence.
2. We tell RX to emit an event after either 500 ms or 2 consecutive clicks take place within 500 ms.
3. We tell RX to take only the events only with 2 consecutive click
4. Last but not least we subscribe to the event sequence which is our DoubleClick handler
