java - 验证电子邮件不适用于 textInputLayout

Question

我有 textInputLayout，我为其添加了监听器。我正在尝试检查输入的电子邮件是否有效。为此，我编写了以下代码。但它不起作用。即使我提供正确的电子邮件 ID，它也会显示有效的电子邮件 ID。

package com.hari.ga.activities;

import android.content.Intent;
import android.os.Bundle;
import android.support.design.widget.Snackbar;
import android.support.design.widget.TextInputLayout;
import android.support.v7.app.AppCompatActivity;
import android.text.Editable;
import android.text.TextUtils;
import android.text.TextWatcher;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

import com.hari.ga.lending.R;

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

        return EMAIL_ADDRESS_PATTERN.matcher(email).matches();
    }
}

Answer 1

这应该可以，

android.util.Patterns.EMAIL_ADDRESS.matcher(emailText.getText().toString()).matches())
