android - 在 Android Xamarin 中使用我的日历的权限

Question

我想在我用 Xamarin 制作的安卓应用程序中向我的日历添加一个事件。但我不断收到错误消息“需要 android.permission.READ_CALENDAR 或 android.permission.WRITE_CALENDAR”。有人可以帮我吗？这是我的代码......谢谢!!!

    using System;
    using MyApp;
    using MyApp.Droid;

    using Android.Content;
    using Android.Provider;
    using Xamarin.Forms;


    [assembly: Xamarin.Forms.Dependency (typeof (CalendarManager))]

    namespace MyApp.Droid
    {
        public class CalendarManager : ICalendarManager
        {
            public CalendarManager () {}

            //public const string WRITE_CALENDAR = "android.permission.WRITE_CALENDAR";
            //public const string READ_CALENDAR = "android.permission.READ_CALENDAR";


            //android.permission.WRITE_CALENDAR

            public void SaveEvent(DateTime start, DateTime end, string title, string notes, string location, bool allday) 
            {

                ContentValues eventDetails = new ContentValues();

                eventDetails.Put (CalendarContract.Events.InterfaceConsts.Dtstart, start.ToUniversalTime ().ToString ()); 
                eventDetails.Put (CalendarContract.Events.InterfaceConsts.Dtend, end.ToUniversalTime ().ToString ()); 
                eventDetails.Put(CalendarContract.Events.InterfaceConsts.Title, title);
                eventDetails.Put(CalendarContract.Events.InterfaceConsts.EventLocation, location);
                eventDetails.Put(CalendarContract.Events.InterfaceConsts.AllDay, allday);


            eventDetails.Put(CalendarContract.Events.InterfaceConsts.EventTimezone, "UTC");
            eventDetails.Put(CalendarContract.Events.InterfaceConsts.EventEndTimezone, "UTC");

            var ctx = Forms.Context;
            ctx.ContentResolver.Insert(CalendarContract.Events.ContentUri, eventDetails);
        }
    }
}

在AndroidManifest.xml ，您必须声明您的应用需要哪些权限，以便 Android 可以在用户安装该应用时通知用户。

设置读取日历和写入日历权限应该可以解决您的问题。
