活动未保存在日历中 [英] Event not saved in Calendar
本文介绍了活动未保存在日历中的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想直接在日历中保存事件，而无需打开日历应用程序。我发现在某些设备中，该事件未保存在日历中，但在logcat中没有出现任何错误。这是我正在使用的代码，
I want to save an event in the calendar directly, without openning the calendar app. I have found that in some devices the event is not saved in calendar, but I am not getting any error in the logcat. This is the code that I am using,
ContentResolver cr = getContentResolver();
ContentValues values = new ContentValues()
values.put(CalendarContract.Events.DTSTART, DateBuilder.getStartDayCalendar());
values.put(CalendarContract.Events.DTEND, DateBuilder.getEndDayCalendar());
values.put(CalendarContract.Events.TITLE, "Title");
values.put(CalendarContract.Events.DESCRIPTION, "description");
values.put(CalendarContract.Events.CALENDAR_ID, 1);
values.put(CalendarContract.Events.EVENT_TIMEZONE, TimeZone.getDefault().getID());
Uri uri = cr.insert(CalendarContract.Events.CONTENT_URI, values);
有人知道发生了什么吗？
Does anyone know what is happening?
谢谢！
更新
在同一设备上，您需要设置状态， Events.STATUS，Events.STATUS_CONFIRMED ，就是问题所在
In same devices you need to set up the status,Events.STATUS, Events.STATUS_CONFIRMED, that was the problem
推荐答案
找到解决方案：
直接按照以下步骤创建事件：
Follow the steps it will create event directly :
Manifest.xml
Manifest.xml
在清单中添加权限
<uses-permission android:name="android.permission.WRITE_CALENDAR" />
<uses-permission android:name="android.permission.READ_CALENDAR" />
activity_main.xml
