Android 向系统日历中添加提醒（踩坑）
代码：

//控制是否事件触发报警，提醒如下

calendarUri = calendarUri.buildUpon()
.appendQueryParameter(CalendarContract.CALLER_IS_SYNCADAPTER, "true")
.appendQueryParameter(Calendars.ACCOUNT_NAME, "[email protected]")
.appendQueryParameter(Calendars.ACCOUNT_TYPE, "com.android.exchange")
.build();
getContentResolver().insert(calendarUri, value);
}
}布局文件：
这里说一下有两个地方需要注意：
1、设置提前几分钟提醒时，如果是准时提醒的话需要设置为0
// 提前5分钟有提醒(提前0分钟时，值为0)
values.put(CalendarContract.Reminders.MINUTES, 5);2、需要设置 提醒的次数
values.put(CalendarContract.Reminders.METHOD, 1);
