我的问题是，如果我输入用户名，密码，电子邮件注册失败Toast消息，那么任何人都可以在后台任务类和主要活动中解决这个问题吗？

请任何一个人进入它看起来像注册成功吗？

 public void submitDetails(View v) 

{




        String username = et.getText().toString();
        String password = et1.getText().toString();
        String email = et2.getText().toString();

        String emailpatern = "^[_A-Za-z0-9-\\+]+(\\.[_A-Za-z0-9-]+)*@"
                + "[A-Za-z0-9-]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$";
        if (username.equals("")) {
            et.setError("pls enter name");
        } else if (password.equals("")) {
            et1.setError("pls enter last name");
        } else if (email.equals("")) {
            et2.setError("Pls Enter Valid Email");
        } else if (!email.matches(emailpatern)) {
            et2.setError("Pls Enter Valid email charcters");
        }
