In the last Article you learnt about MainActivity class. Let’s look at the Layout XML file.
The Layout file is responsible for the User Interface (UI). It’s what you see when you Launch an App.
The File can have Text, Buttons and other elements. Just like a website.
Go ahead an open the content_main.xml file in the new Project. As you can see this XML file contains two primary XML tags:
1. RelativeLayout : This Element tells Android to put elements relative to each other.
2. TextView : This Element is used to display Text.
The android:text attribute in the TextView element is used to display Text. Go ahead and modify this. Save and test. In the next Video we will add a Button to this Layout file.
