【问题描述】:
我有我为其添加了侦听器的 textInputLayout。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。即使我提供了正确的电子邮件 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;
