I like to do it as an extension to Context so you can call it anywhere
fun Context.showKeyboard(editText: EditText) {
val inputMethodManager: InputMethodManager =
getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
inputMethodManager.toggleSoftInputFromWindow(
editText.applicationWindowToken,
InputMethodManager.SHOW_IMPLICIT, 0
)
editText.requestFocus()
editText.setSelection(editText.text.length)
}
fun Context.hideKeyboard(editText: EditText) {
val imm = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(editText.windowToken, 0)
}
