package com.pratap.cardviews1;

import java.io.Serializable;

public class Student implements Serializable {

 /**

  */
 private static final long serialVersionUID = 1L;

 private String name;

 private String emailId;

 private boolean isSelected;

 public Student() {

 }

 public Student(String name, String emailId) {

  this.name = name;
  this.emailId = emailId;

 }

 public Student(String name, String emailId, boolean isSelected) {

  this.name = name;
  this.emailId = emailId;
  this.isSelected = isSelected;
 }

 public String getName() {
  return name;
 }

 public void setName(String name) {
  this.name = name;
 }

 public String getEmailId() {
  return emailId;
 }

 public void setEmailId(String emailId) {
  this.emailId = emailId;
 }

 public boolean isSelected() {
  return isSelected;
 }

 public void setSelected(boolean isSelected) {
  this.isSelected = isSelected;
 }

}


 Step: 2
======
Now Create an Activity with Recycler with button in the xml layout file.
