Answer 1

嘗試thsi代碼

Intent intent = new Intent(Intent.ACTION_EDIT); 
intent.setType("vnd.android.cursor.item/event"); 
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
startActivityForResult(intent,0); 

Answer 2

由於android日曆通常連接到Google日曆，爲什麼不使用Google Calendar API呢？看看這裏：

http://code.google.com/intl/de-DE/apis/calendar/

取而代之的是谷歌API，你也可以使用的CalDAV協議，這使得它更容易切換到其他一些日曆後端以後。
