Android日期选择器月份为数字 [英] Android Date Picker month as number

问题描述

在Android DatePicker中，在某些操作系统上，其月份显示为"Jan，Feb，Mar ... Dec"，在其他操作系统上，其显示为1,2,3..12

In Android DatePicker, in some OS it shows Month as "Jan, Feb, Mar...Dec", on other it shows as 1,2,3..12

有没有办法使它始终保持一致，以使其始终以月为单位显示1,2,3 .. 12?

Is there a way to make it consistent througthout so that it should display 1,2,3.. 12 always as month?

显示1,2,3..12而不是字符串的原因是对各种语言的本地化支持.

Reason for displaying 1,2,3..12 instead of string is the localization support for various kind of languages.

也建议这样做吗? 谢谢.

Also is it advisable to do so? Thanks.
