A full example of custom fonts in XML using data binding and including font caching.

fontbinding

Easy custom fonts in XML using data binding.

No setup required, no extra Java code, and no custom views.

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:font="@{`alegreya`}"
    />

This example includes a simple font cache that automatically loads names from your assets/fonts folder and lazy-loads typefaces. Just drag and drop font files and use them in XML by their normal or lowercase filenames (e.g. "Roboto-Italic" or "roboto-italic" for Roboto-Italic.otf). That's it!

###Data binding Make sure to use the data binding framework to inflate your layout.

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        DataBindingUtil.setContentView(this, R.layout.activity_main);
    }
}

###Custom naming You can set custom names for your fonts, but you don't have to.

FontCache.getInstance().addFont("alegreya", "Alegreya-Regular.ttf");

##Note: It's not currently possible to define custom attributes in styles using data binding. If you require this, check out Calligraphy by Chris Jenx.
