您可以使用正则表达式,例如:

public static void main(String[]args){
    String regex = "^[_a-z0-9-]+(\\.[_a-z0-9-]+)*@[a-z0-9-]+(\\.[a-z0-9-]+)+$";

    Pattern.matches(regex,"test@test.fr"); //True
    Pattern.matches(regex,"test.test@test.fr"); //True
    Pattern.matches(regex,"testtest.fr"); //False
    Pattern.matches(regex,"test.test@testfr"); //False
    Pattern.matches(regex,"test@test."); //False
    Pattern.matches(regex,"test@te@st.fr"); //False

}

所以对你的例子来说:

String regex = "^[_a-z0-9-]+(\\.[_a-z0-9-]+)*@[a-z0-9-]+(\\.[a-z0-9-]+)+$";
    String mail = mailResponsable.getText();

    if(Pattern.matches(regex,mail)) responsableTechnique.setMail(mail);
