In Kotlin Language you can do like this

tv_search.addTextChangedListener(mTextWatcher)

private val mTextWatcher: TextWatcher = object : TextWatcher {
        private var timer = Timer()
        private val DELAY: Long = 1000L

        override fun afterTextChanged(s: Editable?) {
            timer.cancel()
            timer = Timer()
            timer.schedule(object : TimerTask() {
                override fun run() {
                         //DO YOUR STUFF HERE
                }
            }, DELAY)
        }

        override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {
        }

        override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {
        }

    }
