Try following code in onCreate()
int titleId = getResources().getIdentifier("action_bar_title", "id",
"android");
TextView txtTitle = (TextView) findViewById(titleId);
txtTitle.setTextColor(getResources().getColor(R.color.title_color));
txtTitle.setTypeface((Typeface.createFromAsset(this.getAssets(),"FuturaBoldBT.ttf")));
Hope this helps
