android: how to set custom font for entire application

Question

I have developed a very huge application and now i have a requirement of having custom font for all controls in the application. so I want to know the better way to change the font in one shot. The application has more than a hundred XML layout. and i cant change all controls to a custom component with custom font. Please provide a solution to Change the font without altering all the controls in XML.

Answer 1

Do something like this

pacage com.prac;
class MyFontedTextView extends TextView {
    public FontedTextView(Context context) {
        super(context);
        init();
    }

    public FontedTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public FontedTextView(Context context, AttributeSet attrs, int defStyle) {
         super(context, attrs, defStyle);
         init();
    }

    private void init() {
     String otfName = "MyCustomOtfFileWhichIPutInAssetsFolder.otf";
     Typeface font = Typeface.createFromAsset(context.getAssets(), otfName);
     this.setTypeface(font);
    }
}

Now replace this all over in xml file from your TextViews

<com.prac.MyFontedTextView ....        instead of <TextView

This change you have to do all over for it to apply

also for the case of button text . Button is also subclass of TextView So the same can work for button's too

Hope this help or can lead you to the solution you are looking
