How to set Custom Font in whole Application in Android

Question

I want to show my own custom font ".ttf" in my whole application

Please Note... I don't need to change only, "Text view", "Edit text" and "Button" text font by creating Typeface

Answer 1

The only way out is to extend the Android UI widgets and create custom views. But that's a tedious process. Instead, you can use Calligraphy Project:

Are you fed up of Custom views to set fonts? Or traversing the ViewTree to find TextViews? Yeah me too.

Answer 2

You can declare a custom font style in your manifest.xml file under your application tag. For Example:-

    <application
            android:name="com.digimedia.icouch.bean.AppContext"
            android:icon="@drawable/app_logo"
            android:label="@string/app_name"
            android:theme="@style/CustomActionBarTheme" >
