我知道，你可以在Android的应用自定义字体到一个TextView是这样的：

I am aware you can apply a custom TypeFace to a TextView in Android like this:

TextView tv = findViewById(R.id.textview01);
Typeface tf = Typeface.createFromAsset(getAssets(), "fonts/BLACKROSE.TTF");
tv.setTypeface(tf);

有没有什么办法可以做到这一点的一个datepicker？

Is there any way possible to do this for a DatePicker?

推荐答案

在服用一看来源，日期选择器插件拥有3 NumberPicker部件（为日，月，年）这又抱一个TextView。所以，你会需要设置的字体为的DatePicker内NumberPickers内部的TextView的。

After taking a look at the source, the Datepicker widget holds 3 NumberPicker widgets (for day, month, year)which in turn hold a TextView. So you are going have to set the Typeface for the TextView inside the NumberPickers inside the DatePicker.

我认为你必须获得源为NumberPicker和的DatePicker和修改源来实现这一点，谈何容易我害怕。

I think you'll have to get the source for both NumberPicker and DatePicker and modify the source to achieve this, easier said than done I'm afraid.
