Android UI Layout with Android Studio
You can implement a UI L ayout file in Android using Android Studio. Layout Files are nothing but XML files which holds various View/Viewgroups in the form of XML Tags-Attributes. This forms the backbone of an Android Application.
Every single Android Application running should definitely have a Layout file (Maybe not everything, but 99.9%). The layout file helps give the UI for the Android Application.
Creating a Layout file in Android is very simple when you use the Android Studio IDE. Check out the Step by Step procedure below to understand how an Android Layout file is created.
Make sure you have the latest version of Android Studio IDE installed. This provides the environment for you to create your Application. I personally prefer using Android studio over other IDE’s. Find the article on How to Install Android Studio IDE for creating Android Applications to learn to set up your Engine and get going.
We will have to basically understand what the Layout here means. The layout like mentioned above is a set of XML tags, nested with one another and used to implement a layer over layer of UI widgets/elements. The UI Widget could be a Text or an Image etc.
Once you have a sample project created, we jump on to create the Layout. Make sure you have the Android Studio IDE setup and the following Steps are created using that IDE only!
Locate the res folder in the Project structure Tab like below.
On expanding this folder, you are presented with 4 different subdirectories. Our Aim at this point is to create a UI layout.
You press the layout subdirectory and will be creating the layout XML file inside this.
On right clicking the layout folder inside res. We will create the layout by navigating to the New section and navigating to the XML section in picture 2 below.
You find a mini section opening on navigating to the XML section. Click on it to open the Layout XML file.
Once you click on the Layout XML file. You open up a dialog box, wherein you will be entering some details required about the layout file.
The Layout Filename is the name to identify your XML file inside the layout section(You can also think about this as the name of the UI showing up in your application).
The Root Tag represents the different type of Layouts that are available. You can read more about the Layouts in my post about Views and ViewLayout in Android. By default, a LinearLayout file is created which you can use for the UI Layout XML that is generated.
Name the Layout file of your choice and click finish.
Upon processing, the UI Layout is created and we are done with this tutorial as well.
Good Job on creating your First Layout file. We can move forward from here and do a lot of things. For starters, you can read about the post of View & ViewLayout and know how the Layout file is created and what different View and Layouts are present.
