如何在特定的時間和日期開始鬧鐘，我在哪裏得到時間和日期使用TimePicker和DatePicker。即使我可以在用戶指定的時間開始鬧鐘，但我無法在用戶指定的日期進行鬧鐘。我怎樣才能達到我的目標？ 我已經完成的代碼。如何在特定日期和時間啓動鬧鐘？

例如： 我想設置鬧鐘在2013年5月4日下午12:00 ..我怎樣才能做到這一點？
使用'Calendar（）方法''Calendar'實例。告訴我們你有什麼，所以我們可以幫助 – codeMagic
@codeMagic如果我得到日曆實例它會得到設備時間正確嗎？ ？所以用這個設備時間我不能做任何事情，除了顯示。 –
不，您可以使用'日曆'API – codeMagic
