How to force EditText to accept only specific alphanumerical characters?

Question

I want from my EditText to accept only certain characters. I don`t want to filter them in listener, I want to set it in XML permanently.

I want to use only these characters: 0123456789abcdefghijklmnopqrstuvwyzABCDEFGHIJKLMNOPQRSTUVWYZ

So I made string and add that to android:digits. I want to convert each lowercase letter to uppercase (I dont want to disable typing without shift just convert them)

I used android:textAllCaps="true" but this doesnt work.

you can put validation string for this in your class file – niceumang Jun 07 '19 at 14:14 — niceumang, Jun 07 '19 at 14:14
