我想直接在日历中保存活动，而无需打开日历应用。我发现在某些设备中，事件不会保存在日历中，但我没有在logcat中收到任何错误。这是我正在使用的代码，
Events.STATUS, Events.STATUS_CONFIRMED有谁知道发生了什么事？
谢谢！

在相同的设备中，您需要设置状态Content-Type，这是问题

找到解决方案：
按照直接创建活动的步骤：
的Manifest.xml
在Manifest中添加权限
<uses-permission android:name="android.permission.WRITE_CALENDAR" />
<uses-permission android:name="android.permission.READ_CALENDAR" />
activity_main.xml中
<?xml version="1.0" encoding="utf-8"?>
