我的BroadcastReceiver没有收到任何东西.很可能是我的设置错了,因为我无法在此找到任何好的例子.我需要我的接收器在我的MainActivity中接收一些东西,并更改一个视图.我在 Android项目中有几乎相同的代码,并且它在这里工作,但是在Xamarin中,BroadcastReceivers似乎实现了一点点不同(在Android中,我可以使新的BroadcastReceiver几乎像一个对象,但在Xamarin或C#中,似乎我必须创建自己的类,因此没有相同的可能性直接引用视图).如果我让这个工作,我也会为每个人发布一个完整的工作示例.

以下是我尝试设置它的方法：

[Activity(Label = "GetLocation.Droid",MainLauncher = true,Icon = "@drawable/icon")]
public class MainActivity : Activity
{
    Button button;
    protected override void OnCreate(Bundle bundle)
    {
        // ... varIoUs OnCreate() code

        LocationBroadcastReciever lbr = new LocationBroadcastReciever();
        RegisterReceiver(lbr,new IntentFilter("test"));

    }

    public void SetButtonText(string text)
    {
        button.Text = text;
    }
}

[BroadcastReceiver]
public class LocationBroadcastReciever : BroadcastReceiver
{
    public override void OnReceive(Context context,Intent intent)
    {
        /* My program never get this far,so I have not been able
           to confirm if the bellow code works or not (its from
           another example I saw). */
        //EDIT: It does NOT work. See my answer for a working example
        string text = intent.GetStringExtra("title");
        ((MainActivity)context).SetButtonText(text);
        InvokeAbortBroadcast();
    }
}

在我的IntentService中,我有这个实际运行的方法,但从未到达我的接收器.

private void SendBroadcast(double lat,double lng,string activity)
    {
        Intent intent = new Intent("test");
        intent.PutExtra("title","Updated");
        LocalBroadcastManager.GetInstance(this).SendBroadcast(intent);
    }

这与我工作的Android中的代码几乎相同(只调整了BroadcastReceiver和微调以使其编译).

任何人都可以看到什么错？

编辑
最后得到了这整件事.你可以看到我的答案,一个完整,干净的例子.

LocalBroadcastManager.GetInstance(this).RegisterReceiver(lbr,filter);

var intent = new Intent(this,typeof(LocationBroadcastReciever));

this.SendBroadcast(intent);

[IntentFilter(new []{ "test" })]
[BroadcastReceiver]
public class LocationBroadcastReciever : BroadcastReceiver { ... }
