Is it possible to set a custom font for entire of application?

Question

I need to use certain font for my entire application. I have .ttf file for the same. Is it possible to set this as default font, at application start up and then use it else

Answer 1

There is a great library for custom fonts in android:Calligraphy

here is a sample how to use it.

in Gradle you need to put this line into your app's build.gradle file:

dependencies {
    compile 'uk.co.chrisjenx:calligraphy:2.2.0'
}

and then make a class that extends Application and write this code:

public class App extends Application {
    @Override
    public void onCreate() {
        super.onCreate();

        CalligraphyConfig.initDefault(new CalligraphyConfig.Builder()
                        .setDefaultFontPath("your font path")
                        .setFontAttrId(R.attr.fontPath)
                        .build()
        );
    }
} 

and in the activity class put this method before onCreate:

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

and the last thing your manifest file should look like this:

and it will change the whole activity to your font! it's simple and clean!
