Extensions.kt

fun Activity.hideKeyboard(event: MotionEvent) {
    if (event.action == MotionEvent.ACTION_DOWN){
        val view = currentFocus
        if (view != null) {
            view.clearFocus()
            val outRect = Rect()
            view.getGlobalVisibleRect(outRect)
            if (!outRect.contains(event.rawX.toInt(), event.rawY.toInt())) {
                val inputMethodManager =
                    getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager

                inputMethodManager.hideSoftInputFromWindow(
                    view.windowToken,
                    InputMethodManager.HIDE_NOT_ALWAYS
                )
            }
        }
    }
}

YouActivity

override fun dispatchTouchEvent(event: MotionEvent): Boolean {
        hideKeyboard(event)
        return super.dispatchTouchEvent(event)
    }
