Send Object from one Activity to Another Activity using Serializable We will make a POJO class Person that needs to be sent from ActivityOne to ActivityTwo. The Person class just needs to implement the serializable interface.

However if you need Gender to be generic and u want to use it with animals also, then you might want to keep this enum in a separate class. package com.ekiras.demo; public class User { public enum Gender{ MALE, FEMALE } private String name; private String address; private String email; private String password; private Gender gender = Gender.MALE; } You can also use the enums with parameters inside class as shown below. package com.ekiras.demo; public class User { public enum Gender{ MALE("male"), FEMALE("female"); String value; Gender(String value){ this.value=value; } } private String name; private String address; private String email; private String password; private Gender gender = Gender.MALE; }

How to implement Material Design Tab Layout Android Material Design Tab Layout with toolbar Android Material Design Tab Layout without toolbar looks like the following. You can implement the Tab Layout in android by using the following steps. Step 1 : Add the design dependency in the project dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) testCompile 'junit:junit:4.12' compile 'com.android.support:appcompat-v7:23.1.0' compile 'com.android.support:design:23.1.0' } After adding the dependency, synchronize your project so that gradle downloads and add the dependency. Step 2 : Layout Structure for the activity Your activity structure should be like following. --CoordinatorLayout ----AppBarLayout ------TabLayout ----ViewPager Now let's understand why we need to follow this hierarchy to create the tab layout. CoordinatorLayout provides an additional layer of control over the touch events between child views. It is ...
