Letter or numbers in keyboard

[cla721]

I want my program to display a keyboard, when I touch an EditText.

The keyboard input type shall be Numbers (as selected in the EditText designer).
But, the keyboard shall also allow a single letter (A), (B), (C) etc. to be entered.
Multiple letters, or letters and numbers is not accepted.

Example:
Input OK: 3453
Input OK: D
Input not OK: D3455
Input not OK: DART

Any great ideas how to program that???

Best regards

You will have to use Regular Expresions (Regex + matcher)
