How to insert an email in android application in android version 8

In the next step, select the activity_main.xml file to access the front-end side of the android application.

Step 4: Go to the design tab and select email under text.

Step 5: Drag and drop email on your android application preview.

After getting the email edit text XML file will look like this:-

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
    android:id="@+id/layout">


    <EditText
        android:id="@+id/editText3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_marginTop="173dp"
        android:ems="10"
        android:inputType="textEmailAddress" />
</RelativeLayout>

android:inputType="textEmailAddress"

This line represents an Edit text as an textEmailAdress i.e. this Edit Text will be used to insert email from the user.

After the step 5, front-end work is completed, you can take a button for 'submit' according to your requirement. You can also go through my android Button tutorial to understand the working of button in android application.

Step 6: Insert the following code in your Main Activity file:

import android.widget.EditText;

Step 7: Insert the following code in your MainActivity class:

private EditText email;

This will create an instance variable of class EditText as email.

Step 8: Inside the onCreate method of your MainActivity class, insert the following code:

email=findViewById(R.id.editText);
String mail=email.getText().toString();

This will initialize the email instance.

Step 9: In the final step, you can use the String mail to get the email inserted by the user.

Developer may check the email-address entered by the user against the email in his database via mail String.

I would suggest you to take a button to insert the email from the user.

Insert the following code on your onCreate method inside the

MainActivity.java file:

if(mail==HR@javatpoint.com){
Toast.makeText(MainActivity.this,"Welcome HR@javatpoint.com",Toast.LENGTH_SHORT).show();
}
else{
Toast.makeText(MainActivity.this,"Not a valid user",Toast.LENGTH_SHORT).show();
}
