Question

我尝试了以下代码来设置PickerComponent的startDate和endDate：

CSS：

    Form f = new Form(new TextModeLayout(1, 1));
    int MINAGE = 13;

    Calendar minAge = Calendar.getInstance(); // it's not a singleton, https://stackoverflow.com/questions/6055112/why-can-i-have-only-one-instance-of-calendar-object
    minAge.setTime(new Date()); // current time
    int year = minAge.get(Calendar.YEAR) - MINAGE;
    minAge.set(Calendar.YEAR, year);
    Date endDate = minAge.getTime();

    Calendar maxAge = Calendar.getInstance();
    maxAge.setTime(new Date());
    maxAge.set(Calendar.YEAR, 1930);
    maxAge.set(Calendar.MONTH, 1);
    maxAge.set(Calendar.DAY_OF_MONTH, 1);
    Date startDate = maxAge.getTime();

    PickerComponent inputCmp = PickerComponent.createDate(endDate).label("Birthday");
    Log.p("startDate: " + startDate.toString());
    Log.p("endDate: " + endDate.toString());
    inputCmp.getPicker().setStartDate(startDate);
    inputCmp.getPicker().setEndDate(endDate);

    f.add(inputCmp);
    f.show();

MainClass：

[EDT] 0:0:0,293 - startDate: Sat Feb 01 12:30:58 CET 1930
[EDT] 0:0:0,307 - endDate: Fri Dec 02 12:30:58 CET 2005
[EDT] 0:0:2,227 - Exception: java.lang.ArrayIndexOutOfBoundsException - Index out of bounds

但是当我尝试在选择器中选择日期时，我得到了：

{{1}}

在模拟器中测试。

Answer 1

这是Picker中的错误，我过去曾要求用户对此提交问题，但似乎他没有。似乎picker的默认行为是将1970显示为最早的日期。这显然是有问题的，应该解决。

代号一个PickerComponent setStartDate和setEndDate的用法
