A CustomTextView class which removes the need for applying the custom fonts for each TextView

==============

Implementation:

1. Under /res/values/ folder create attrs.xml file with the following cotents:

    <?xml version="1.0" encoding="utf-8"?>
   

     <declare-styleable name="CustomTextView">
        <attr name="fontAssetName" format="string"/>
    </declare-styleable>
   

2. Add your desired fonts in /assets folder like "Politica XT.otf" font

==============

Usage:

Simply set the fontAssetName attribute to an EXISITING font file name in your assets folder

<?xml version="1.0" encoding="utf-8"?>

<com.my.app.CustomTextView
        xmlns:custom="http://schemas.android.com/apk/res/com.my.app"            
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Test text"
        android:id="@+id/testcustomview" 
        
        custom:fontAssetName="Politica XT.otf"
        />
<Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Back"
        android:id="@+id/button"/>
