Validation not to take Special Character only character in Uppercase

Question

I want to restrict special character when user type on edittext, how I can achieve it, I tried:

public boolean validateBuisnessName(EditText et, String name, TextInputLayout textInputLayout) {
  String alphaRegex = ".*[A-Z0-9].*";

  // Check if pattern matches
  if (name.matches(alphaRegex)) {
     textInputLayout.setErrorEnabled(false);
  } else {
     textInputLayout.setError("Invalid Buisness Name");
     return false;
  }
  return true;
}
