Custom Fonts

In android, you can define your own custom fonts for the strings in your application. You just need to download the required font, and then place it in assets/fonts folder. Y ou can access it in your java code through Typeface class. - Use setTypeface() method TextView textView = (TextView) findViewById(R.id. TextView1 ) ; Typeface custom_font = Typeface. createFromAsset (getAssets() , "fonts/font name.ttf" ) ; textView.setTypeface(custom_font) ;
