How to insert "+" into TextInputEditText permanently while dialing?

Question

Android

I need when dialing a number so that "+" is already displayed in the TextInputEditText and applies to all digits

Answer 1

Well, add this "+" symbol to the field of your TextInputEditText after initialization and actually before showing it to the user.
Either to the left of the TextInputEditText , in a separate TextView , write this "+" symbol to inform the user that it is no longer necessary to write it, and then do a simple validation, controlling the correctness of the entered number, or removing the extra "+" from there, etc.
