First let’s add the latest support library.
If you start the quiz you’ll get a series of 5 questions which ask you to guess the font of the text.īut wait – the text is always in the same (default) font! We’ll get to that shortly. Once the project is open and synced, build and run the project. Select the location where you extracted the starter project and click Open on the dialog. Open up Android Studio and import the starter project with File\Open. You can download the starter project here. Your first task will be to switch to the latest support library. Install Android Studio by following the instructions in our Beginning Android development tutorial. This is important as some of the features are not supported on Android Studio 2.x – for example the font resource directory. To work with custom fonts you’ll first have to install the latest Android Studio 3.x. Not to mention that it felt wrong extending a TextView just for setting a custom font.
In some cases things could get messy – for example if you had to change the font on Toolbar. On some devices loading from assets could take a long time so you had to cache fonts in memory. You had to extend every type of View you wanted to apply a custom font to. That was a little bit better but there were still issues: To remedy that you could extend your view classes and add a custom attribute for passing the font file from layout. Val myTypeface = Typeface.createFromAsset(assets, "fonts/myFont.ttf") The main disadvantage in this approach was that you couldn’t set the font in layout files – you had to do it in code: Set that Typeface to your view using setTypeface(). 
Load the font from the asset file into a Typeface object. Put your font files in the assets folder. Up until recently, to use a custom font on a View, you had to do several things: If you are new to Android development, check out our Android Tutorials first. If you are new to Kotlin check out our Kotlin introduction tutorial. Note: This tutorial assumes you know the basics of Android development with Kotlin.
