How to change the default font in an Android app?

  • 772

I have an example of how to change the font to a text, but what I need is to apply it globally so I don't have to put it on each TextView:

public class ActividadEjemplo extends AppCompatActivity {

TextView text;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_ejemplo);
    text = (TextView)findViewById(R.id.txt1);
    String font_path = "font/Quicksand-Regular.ttf";
    Typeface fuente = Typeface.createFromAsset(getAssets(),font_path);
    text.setTypeface(fuente);
}
}
java

    To use Calligraphy quickly, create your project and add the reference to the library

    dependencies {
   compile 'uk.co.chrisjenx:calligraphy:2.1.0'
}

    Then you create a class that does an extends to the Application class

    MyApplication.java

    public class MiAplicacion extends Application {

  @Override
  public void onCreate() {
      super.onCreate();
      CalligraphyConfig.initDefault(new CalligraphyConfig.Builder()
                    .setDefaultFontPath("fonts/Roboto-Regular.ttf")
                    .setFontAttrId(R.attr.fontPath)
                    .build()
      );
  }
}

    Then in your AndroidManifest.xml file, inside the application tag in the android:name property, you put the name of your previously created class, looking like this:

    <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.brandot">

  <application
    android:name=".MiAplicacion"
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/title_name"        
    android:theme="@style/AppTheme">
    <activity
        android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>        
  </application>
</manifest>

    Then inside your project in the assets directory you place your fonts, in my case I have assets/fonts/Roboto-Regular.ttf . And then in your Main class you add the following:

    public class MainActivity extends AppCompatActivity {

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

  @Override
  protected void attachBaseContext(Context newBase) {
    super.attachBaseContext(CalligraphyContextWrapper.wrap(newBase));
  }
}

    This way you make all your components inside the activity load the default font, which in this case is Roboto-Regular.ttf .

  2. To do it globally I recommend using Calligraphy . You can define global fonts for the entire application or even assign fonts found in your assets within the XML.

    UPDATE

    First you need to add it to your gradle file as a dependency:

    dependencies {
    compile 'uk.co.chrisjenx:calligraphy:2.1.0'
}

    You must have a class that extends from Applicationto which you must add the following code in its method onCreate():

    CalligraphyConfig.initDefault(new CalligraphyConfig.Builder()
                .setDefaultFontPath("fonts/Raleway-Light.ttf") //Fuente agregada en los assets dentro de la carpeta fonts
                .setFontAttrId(R.attr.fontPath)
                .build());

    Finally in each Activityone that you want to have the default fonts, you have to add the following code:

     @Override
 protected void attachBaseContext(Context newBase) {
        super.attachBaseContext(CalligraphyContextWrapper.wrap(newBase));   
 }

    All this information is also available in the Github repository of this library.
