我已经实现了API提供的HelloDatePicker的演示版.

I have implemented the Demo version of HelloDatePicker provided by the API.

但是，旋转屏幕后，我无法保持其值.有人可以张贴示例或说明如何做到这一点.

However I cannot maintain its value after rotating the screen. Can someone post an example or indicate how one can do this.

谢谢

推荐答案

使用 onRetainNonConfigurationInstance()保存日期，在onCreate中使用

Use onRetainNonConfigurationInstance() to save the date, and in onCreate use getLastNonConfigurationInstance() to load and set the date.
