I am trying to swap out calligraphy (very useful library) for android fonts in xml but i dont know how to change the default font for all views like with calligraphy. Calligraphy was able to change the default font at initialization time. How can i do this with android fonts support library ?
from the fonts in xml article on android developer site i see we can apply a font family to one view like this:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:fontFamily="@font/lobster"/>
but what if i want to change the font of the entire app ?
the reason i'd like to use android xml fonts is due to this error but this is not really relevant to the question.
With the Support Library 26.1.0 I managed to have a default font for the whole app by setting the android:fontFamily attribute for the application theme:
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
...
<item name="android:fontFamily">@font/proxima_nova</item>
</style>
Where proxima_nova.xml is a font resource file:
<?xml version="1.0" encoding="utf-8"?>
<font-family xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:ignore="UnusedAttribute">
<!-- As of Android Support Library 26.0, we must declare both sets of attributes to ensure
our fonts load on devices running Android 8.0 (API level 26) or lower. -->
<font
android:font="@font/proxima_nova_light"
android:fontStyle="normal"
android:fontWeight="300"
app:font="@font/proxima_nova_light"
app:fontStyle="normal"
app:fontWeight="300" />
<font
android:font="@font/proxima_nova_semibold"
android:fontWeight="600"
app:font="@font/proxima_nova_semibold"
app:fontWeight="600" />
</font-family>
