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

I would suggest extending TextView, and always using your custom TextView within your XML layouts or wherever you need a TextView. In your custom TextView, override setTypeface

@Override
public void setTypeface(Typeface tf, int style) {
    //to handle bold, you could also handle italic or other styles here as well
    if (style == 1){
        tf = Typeface.createFromAsset(getContext().getApplicationContext().getAssets(), "MuseoSans700.otf");
    }else{
        tf = Typeface.createFromAsset(getContext().getApplicationContext().getAssets(), "MuseoSans500.otf");
    }
    super.setTypeface(tf, 0);
}
