Avoid button multiple rapid clicks

Question

I have a problem with my app that if the user clicks the button multiple times quickly, then multiple events are generated before even my dialog holding the button disappear

Answer 1

I use this class together with databinding. Works great.

/**
 * This class will prevent multiple clicks being dispatched.
 */
class OneClickListener(private val onClickListener: View.OnClickListener) : View.OnClickListener {
    private var lastTime: Long = 0

    override fun onClick(v: View?) {
        val current = System.currentTimeMillis()
        if ((current - lastTime) > 500) {
            onClickListener.onClick(v)
            lastTime = current
        }
    }

    companion object {
        @JvmStatic @BindingAdapter("oneClick")
        fun setOnClickListener(theze: View, f: View.OnClickListener?) {
            when (f) {
                null -> theze.setOnClickListener(null)
                else -> theze.setOnClickListener(OneClickListener(f))
            }
        }
    }
}

And my layout looks like this
