Question

那我怎么办才能“打开”我的约会对象数组列表？我尝试了迭代，但是它得到2个正确的显示，或重复最后一个条目。我需要将文本字段设置为对象数组内的变量。我该怎么办？这是一个将约会保存到数组列表中的日历，该列表是该列表的对象类型，称为约会。我已经快要完成了，以至于无法在文本字段中显示或设置信息。

代码写得不好。只需考虑所有天的代码有多相似。为什么要重复自己，而不是想出一个合适的数据结构来让您更方便地访问对象？当您可以创建2个并使用循环重复该过程时，为什么还要创建2个x 7 TextField呢？

您需要做的另一件事实际上是将星期几存储在您的Appointment中。

以下代码中的open实现假定date列表中的内容已经包含正确的值，即使当前代码仅恢复最后提交的值（如果用户编辑了{{1 }}。
