Answer 1

嗨，使用此代码，我认为这将对您有所帮助

String str_newEmail = "Bharath@in.com,bharath@appsforbb.co.in";
    String[] test = str_newEmail.split(",");
    for (int i = 0; i < test.length; i++) {
        if (!validEmail(test[i])) {
            System.out.println("This is not a vaild email");
            break;
        }
    }

电子邮件方法的验证。

    public boolean validEmail(String str_newEmail) {

    return str_newEmail.matches("^[_A-Za-z0-9-\\+]+(\\.[_A-Za-z0-9-]+)*@"
            + "[A-Za-z0-9-]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$");
}

Answer 2

private boolean isValidEmail(CharSequence target) {
    boolean emailflag = false;
    String emailArr[] = target.toString().split("[,]");
    for (int i = 0; i < emailArr.length; i++) {
        emailflag = android.util.Patterns.EMAIL_ADDRESS.matcher(
                emailArr[i].trim()).matches();
    }
    return emailflag;
}

您还可以使用 StringTokenizer：

String emails = "Bharath@in.com,bharath@appsforbb.co.in";
StringTokenizer st = new StringTokenizer(emails, ",");

while (st.hasMoreElements()) {
  String email = st.nextToken();
  if (!validEmail(email)) {
      System.out.println("Invalid email:" + email);
  }
}
