Android OnClickListener Prevent multiple clicks

 * A Debounced OnClickListener
 * Rejects clicks that are too close together in time.
 * This class is safe to use as an OnClickListener for multiple views, and will debounce each one separately.
 * This class allows a single click and prevents multiple clicks on
 * the same button in rapid succession. Setting unclickable is not enough
 * because click events may still be queued up.
 *
 * Override onOneClick() to handle single clicks. Call reset() when you want to
 * accept another click.

///////USAGE
view.findViewById(R.id.cancelBtn).setOnClickListener(new SafeOnClickListener() {

“Thanks for this class; you helped a lot. I recreated this class in Kotlin, and I’ll share it along with some extension functions for Android in Kotlin.”

Extension

fun View.setSafeOnClickListener(onSafeClick: (View?) -> Unit) {
    this.setOnClickListener(object : SafeOnClickListener() {
        override fun onOneClick(v: View?) {
            onSafeClick(v) // Llamada a la acción segura definida en la extensión
        }
    })
}

Use

binding.reprintTicketsDateRangeEditText.setSafeOnClickListener { view ->
   view?.let { showDatePicker() }
 }
