我已经实现了一个 Android 应用程序，并且刚刚添加了MonkeyTalk库，通过记录用户与应用程序的交互来测试系统的可用性。

使用这个库后，一切正常，但是 DatePicker！

我使用以下方法显示 DatePicker 对话框：

private void setSpecificDate() {

    int mYear = calendar.get(Calendar.YEAR);
    int mMonth = calendar.get(Calendar.MONTH);
    int mDay = calendar.get(Calendar.DAY_OF_MONTH);
    DatePickerDialog dpd = new DatePickerDialog(getActivity(), 
            new OnDateSetListener() {

                @Override
                public void onDateSet(DatePicker view, int year, int monthOfYear,
                        int dayOfMonth) {

                // part of code uses retrieved data from DataPicker...

                }
            }, mYear, mMonth, mDay);
    dpd.show();
}

然后，只要我点击显示 DatePicker，它就会崩溃，我得到运行时错误，程序失败！

当我只是注释掉dpd.show();它时它可以工作，但没有任何反应。

我还测试了使用 TimePicker 而不是 DatePicker 来检查应用程序的行为，并且成功了！

运行时错误：
