You will now see a dialog where you can give a name to the style and also select the attributes that should be included in it. To create a new style for the first view, right click on it and select Refactor > Extract > Style. Therefore, let's start by creating a new empty activity and adding two views to its layout XML file.Īs you can see in the above code, properties such as layout_width and layout_margin are explicitly included in the definition of each view. Styles are obviously applied to UI components. You'll also learn how to use Android Studio's tools and shortcuts that facilitate style creation. In this tutorial, you'll learn how to create custom styles and themes for your Android apps. If you are familiar with web development, the first approach is akin to using inline CSS styles, and the second approach is akin to using style sheets. The second approach involves creating and using custom styles and themes. This approach is feasible only if you are working on a simple app that has a small number of views and activities. The first approach involves directly modifying the properties of views in layout XML files. There are two approaches to modifying the look of Android apps. If you find that hard to believe, I suggest you take a quick look at the apps in the Top Charts section of Google Play.
On Google Play, which hosts well over a million apps today, looks are just as important as functionality, if not more. Functionality alone, however, is rarely enough. As Android developers, we tend to focus primarily on the functionality of our apps.
