Android API 21 22 datepicker年度选择错误? [英] Android API 21 22 datepicker year selection bug?

问题描述

我已经实现了日历视图"，即Android的Datepicker的棒棒糖版本. Android API 21&当我单击"2015"以更改年份时，在所述日期选择器的年份选择中选择22:

I've implemented the "calendar view", i.e., lollipop version of Android's Datepicker. There's a difference between Android API 21 & 22 in the year selection of said datepicker when I click on "2015" to change the year:

使用API​​21

使用API​​22

我正在使用Nexus 5模拟器.我仅在API22中看到当前(2015年)条目，而在API21中，我可以从〜1950滚动到〜2100.据我所知，相同的代码和相同的仿真设置.

I'm using a Nexus 5 simulator. I'm only seeing the current (2015) year entry in API22, whereas in API21, I can scroll through from ~1950 to ~2100. Same code and, as far as I can tell, same simulation settings.

我想知道这是否只是一个bug，是否有人遇到过bug，或有任何解决方法的提示?我真的很喜欢Lollipop提供的日历视图，如果我能正确地使用它的话，它是如此可取.将使用我发现的任何新信息进行更新.

I'm wondering if this is just a bug, if anyone else has encountered it, or has any tips for a workaround? I really like the calendar view that Lollipop offers so preferable if I can get this working right. Will update with any new information I find.

推荐答案

找到了快速解决方案.以编程方式设置DatePickerDialog对象的最小和最大日期.我是在 DatePickerFragment静态类定义中这样做的，所以每个DatePickerDialog实例都会被设置:

Found a quick fix. Programmatically set the min and max dates of the DatePickerDialog object. I did so in the DatePickerFragment static class definition, so every instance of DatePickerDialog gets set:

DatePickerDialog datePickerDialog = new DatePickerDialog(getActivity(), YourActivityHere, year, month, day);
datePickerDialog.getDatePicker().setMinDate(datePickerDialog.getDatePicker().getMinDate());
datePickerDialog.getDatePicker().setMaxDate(datePickerDialog.getDatePicker().getMaxDate());

如果您在XML活动中定义了DatePickerDialog，也可以进行设置，但是我不确定该错误是否存在.

You can also set this if you defined DatePickerDialog in an XML activity, but I'm not sure if the bug exists there.
