How about something like this:

import android.app.Activity
import android.content.Context
import android.view.View
import android.view.inputmethod.InputMethodManager
import android.widget.EditText
import androidx.fragment.app.Fragment

/**
 * Hide the soft keyboard if visible
 */
fun Fragment.hideKeyboard() {
    view?.let { activity?.hideKeyboard(it) }
}

/**
 * Hide the soft keyboard if visible
 */
fun Activity.hideKeyboard() {
    hideKeyboard(currentFocus ?: View(this))
}

/**
 * Hide the soft keyboard if visible
 */
fun Context.hideKeyboard(view: View) {
    val inputMethodManager = getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
    view.clearFocus()
    inputMethodManager.hideSoftInputFromWindow(view.windowToken, 0)
}

/**
 * Show the soft keyboard for this EditText.
 * Will request focus and move the cursor to the end.
 */
fun EditText.showKeyboard() {
    if (this.requestFocus()) {
        val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
        this.setSelection(this.text.length);
        imm.showSoftInput(this, 0)
    }
}
