How to return to OnClickListener from inside a function that gets invoked by a click on Button?

I have some lines code that prevents multiple quick click on a button. If I use that code every time inside Button.OnClickListener, it works fine. But calling the same code every time is not a good idea, so I wanted to keep the code as a global function and call the function when needed.

Here is my code:

lastClickTime = 0L
MyButton.setOnClickListener {
     if (SystemClock.elapsedRealtime() - lastClickTime < 1000) {
          return@setOnClickListener
     }
     lastClickTime = SystemClock.elapsedRealtime()

I am trying to make a global method to call from every Button.OnClickListener. But I couldn't figure it out what code can replace return@setOnClickListener.

var lastClickTime = 0L
fun preventMultiQuickClick() {
    if (SystemClock.elapsedRealtime() - lastClickTime < 1000) {
        //I WANT TO RETURN TO THE button.setOnClickListener 
        //OF THE BUTTON WHICH INVOKES THIS FUNCTION LIKE IN ABOVE CODE
    }
    lastClickTime = SystemClock.elapsedRealtime()
}


Button.setOnClickListener {
    preventMultiQuickClick()
    //do other stuffs
}

How can I achieve this? Any help will be highly appreciated.

You can do it like this:

var lastClickTime = 0L
fun preventMultiQuickClick(): Boolean  {
    return if (SystemClock.elapsedRealtime() - lastClickTime < 1000) {
        false
    }
    lastClickTime = SystemClock.elapsedRealtime()
    true
}


Button.setOnClickListener {
    if(!preventMultiQuickClick()) {
        //do other stuffs
    }
}
