android程序更换字体,Android更改应用程序的字体类型？

我在我的应用程序中需要字体字体Helvetica并适用于所有活动.有什么来源吗&＃xff1f;

我在资产文件夹中有Helvetica.ttf文件但是当我尝试时

TextView text2 &＃61;(TextView)findViewById(R.id.textView2);

Typeface font &＃61; Typeface.createFromAsset(getAssets(), "helvetica.ttf");

text2.setTypeface(font);

但错误是::

通过手动捆绑应用程序中的字体并手动将其应用于每个TextView(或子类),是的.
