Call this function to hide the system keyboard:

fun View.hideKeyboard() {
    val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    imm.hideSoftInputFromWindow(windowToken, 0)
}

I slightly modify response of @Serj Ardovic

private fun hideKeyboard(view: View) {
    view?.apply {
        val imm = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
        imm.hideSoftInputFromWindow(view.windowToken, 0)
    }
}

as its really works for my requirement

You can extend all EditText with new function, which will be hide soft keyboard always when focus for EditText is lost. If you want hide keyboard, when focus for some EditText is lost, just use this line of code for this EditText

editText.hideSoftKeyboardOnFocusLostEnabled(true)

In extension for EditText we just add or remove our own OnFocusLostListener

fun EditText.hideSoftKeyboardOnFocusLostEnabled(enabled: Boolean) {
    val listener = if (enabled)
        OnFocusLostListener()
    else
        null
    onFocusChangeListener = listener
}

Here is implementation of OnFocusLostListener which hides keyboard if focus for attached View is lost.

class OnFocusLostListener: View.OnFocusChangeListener {
    override fun onFocusChange(v: View, hasFocus: Boolean) {
        if (!hasFocus) {
            val imm = v.context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
            imm.hideSoftInputFromWindow(v.windowToken, 0)
        }
    }
}

fun hideSoftKeyboard(mActivity: Activity) {
        // Check if no view has focus:
        val view = mActivity.currentFocus
        if (view != null) {
            val inputManager = mActivity.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
            inputManager.hideSoftInputFromWindow(view.windowToken, 0)
        }
    }

    fun showKeyboard(yourEditText: EditText, activity: Activity) {
        try {
            val input = activity
                    .getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
            input.showSoftInput(yourEditText, InputMethodManager.SHOW_IMPLICIT)
        } catch (e: Exception) {
            e.printStackTrace()

        }
    }
