Navigating through an app

In this section, we will cover how to navigate between fragments in your app. To keep things simple for the chapter, we will build upon our existing SampleActivity example and show how to add simple navigation to our application.

Activity navigation

Navigating between activities is one of the simplest actions that you can perform and is very commonly used. In the following example, we will show how to move from one instance of our SampleActivity (which we will refer to as activity A) to another instance of SampleActivity (which we will refer to as activity B). As we have already added the SampleActivity to our Android app manifest, we do not need to add an additional entry.

First, we will start by modifying the layout file to add an extra view. This view is a Button, and we will hook up this button to perform the activity navigation. The updated layout file should look like this:

<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res...
