设置初始时间问题

picker.setRangeStart(2016, 8, 29); DatePicker中这个设置起始时间的貌似不太管用啊，不管设置多少 最早时间都是2010年的，我获取当前的year,month,day想设置成下面这样的
picker.setRangeEnd(year + 2, month, day);
picker.setRangeStart(year, month, day);
picker.setSelectedItem(year, month, day);

Start with the DatePicker implementation and the setRangeStart, setRangeEnd, and setSelectedItem entry points. Reproduce the reported setup using the current date and verify why the earliest selectable date remains 2010; done means the configured start date limits the picker as expected.
