Question

我已经在我的应用程序中实现了电子邮件验证，但问题是应用程序接受超过64个字符的本地域部分，当我写..nnn .. @ gmail.com应用程序也接受这个以及根据RFC 3696规范＃section 3，句点（“。”）不得用于开始或结束本地部分，也不得出现两个或多个连续句点。

请帮帮我

Answer 1

Android SDK有一个内置的正则表达式，用于检查电子邮件。

Patterns JavaDoc

Matcher matcher = Patterns.EMAIL_ADDRESS.matcher(email);
return matcher.matches();

Answer 2

试试这段代码。如果电子邮件有效，则返回true。

android.util.Patterns.EMAIL_ADDRESS.matcher(email).matches();

Answer 3

public final static boolean isValidEmail(CharSequence target) {
    if (TextUtils.isEmpty(target)) {
        return false;
    } else {
        return android.util.Patterns.EMAIL_ADDRESS.matcher(target).matches();
    }
}

Answer 4

试试这个，

String expression = "[a-zA-Z0-9._-]+@[a-z]+\\.+[a-z]+";

Answer 5

尝试这个

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class EmailValidation {
private Pattern pattern;
private Matcher matcher;

private static final String EMAIL_PATTERN = 
    "^[_A-Za-z0-9-\\+]+(\\.[_A-Za-z0-9-]+)*@"
    + "[A-Za-z0-9-]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$";

public EmailValidation() {
    pattern = Pattern.compile(EMAIL_PATTERN);
}

public boolean isValidate(final String hex) {
    matcher = pattern.matcher(hex);
    return matcher.matches();
  }
}

Answer 6

我建议在所有这些答案中提供一个简单的解决方案

public static boolean isEmail(String email){
  return android.util.Patterns.EMAIL_ADDRESS.matcher(inputData.trim()).matches()
}

阅读有关模式的this文档。

Answer 7

我建议您查看此库以进行Android客户端验证
