Based on above answers like this it works in KOTLIN as long as you have the context.
fun Context.showKeyboard(editText: EditText) {
editText.requestFocus()
editText.setSelection(editText.text.length)
GlobalScope.launch {
delay(200L)
val inputMethodManager: InputMethodManager =
getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
inputMethodManager.toggleSoftInputFromWindow(
editText.applicationWindowToken,
InputMethodManager.SHOW_IMPLICIT, 0
)
}
}
Then you can call it in your fragment for example as follows
requireContext().showKeyboard(binding.myEditText)
