    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)
    }

    if you are using Jetpack Compose;

    @Composable
fun MainScreenView(){

    val keyboardController = LocalSoftwareKeyboardController.current
    keyboardController.hide()

    You can make an Extenstion function on the edit text that would do that for you

    fun EditText.hideKeyboard() {
    clearFocus()
    val imm = context.getSystemService(INPUT_METHOD_SERVICE) as InputMethodManager
    imm.hideSoftInputFromWindow(getWindowToken(), 0)
}

    I haven’t tested it out yet, please test that one out and tell me if it does work.

    // on below line getting current view.
    val view: View? = this.currentFocus

            // on below line checking if view is not null.
        if (view != null) {
            // on below line we are creating a variable
            // for input manager and initializing it.
            val inputMethodManager =
                getSystemService(INPUT_METHOD_SERVICE) as InputMethodManager
             
            // on below line hiding our keyboard.
            inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(), 0)
             
            // displaying toast message on below line.
            Toast.makeText(this, "Key board hidden", Toast.LENGTH_SHORT).show()
