Monodroid Intent Service的BroadcastReciever没有触发OnReceive

Question

好吧，所以我一直在尝试为monodroid essentially going off of this source material运行玩具意图服务而且我遇到了一些问题而且我已经把它归结为广播接收器了。更重要的是我对ACTION_RESP字符串的怀疑。如果没有别的，我当然可以确认这一点，也许正确的方式来设置接收者可以看到的动作 所以，这就是我迄今为止所拥有的......

我的意图服务

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using Android.App;
using Android.Content;
using Android.OS;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using Android.Util;

namespace Mono_For_Android_Intent_Service
{
    [Service]
    public class TestIntentService : IntentService
    {
        public static String PARAM_IN_MSG = "imsg";
        public static String PARAM_OUT_MSG = "omsg";

        #region Constructor
        public TestIntentService()
            : base("TestIntentService")
        {
        }
        #endregion

        protected override void OnHandleIntent(Intent intent)
        {
            string msg = intent.GetStringExtra(PARAM_IN_MSG);
            //Do Stuff
            string result = msg + " " + DateTime.Now.ToString();
            Intent BroadcastIntent = new Intent(this,typeof(Mono_For_Android_Intent_Service.MainActivity.MyBroadcastReceiver));
            BroadcastIntent.SetAction(Mono_For_Android_Intent_Service.MainActivity.MyBroadcastReceiver.ACTION_RESP);
            BroadcastIntent.AddCategory(Intent.CategoryDefault);
            BroadcastIntent.PutExtra(PARAM_OUT_MSG,result);
            SendBroadcast(BroadcastIntent);
        }
    }
}

主要活动和广播接收器

using System;

using Android.App;
using Android.Content;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using Android.OS;

namespace Mono_For_Android_Intent_Service
{
    [Activity(Label = "Mono_For_Android_Intent_Service", MainLauncher = true, Icon = "@drawable/icon")]
    public partial class MainActivity : Activity
    {
        private MyBroadcastReceiver Receiver;
        protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);

            // Set our view from the "main" layout resource
            SetContentView(Resource.Layout.Main);

            IntentFilter filter = new IntentFilter(MyBroadcastReceiver.ACTION_RESP);
            filter.AddCategory(Intent.CategoryDefault);
            Receiver = new MyBroadcastReceiver();
            RegisterReceiver(Receiver, filter);

            var button = FindViewById(Resource.Id.start);
            button.Click += (s,e)=>
            {
                Intent msgIntent= new Intent(this,typeof(TestIntentService));
                msgIntent.PutExtra(TestIntentService.PARAM_IN_MSG,"Me message, arh");
                Toast.MakeText(this, "Starting intent service!", ToastLength.Short).Show();
                StartService(msgIntent);

            };

            TextView txtView = FindViewById(Resource.Id.status);
        }

        public class MyBroadcastReceiver : BroadcastReceiver
        {
            public static readonly string ACTION_RESP = "Mono_For_Android_Intent_Service.Intent.Action.MESSAGE_PROCESSED";
            public override void OnReceive(Context context, Intent intent)
            {
                Toast.MakeText(context, "Firing On Receive!", ToastLength.Short).Show();
                var activity = (MainActivity)context;
                TextView txtView = activity.FindViewById(Resource.Id.status);
                txtView.Text = intent.GetStringExtra(TestIntentService.PARAM_OUT_MSG).ToString();
                Toast.MakeText(context, "On Receive complete!", ToastLength.Short).Show();
            }
        }
    }
}

1. 我做错了吗？我接近了吗？我想我非常接近但是，无论如何，如果我在timbucktoo，我想知道......
2. 如果是这样，发送和接收该广播的正确方法是什么？

如果您希望在系统中注册广播接收器，则需要添加[BroadcastReceiver]属性。
