我一直在尝试运行一个适用于monodroid的玩具意图服务,基本上是根据这个资料来源,但我遇到了一些问题,最终发现是广播接收器的问题。最重要的是,我怀疑ACTION_RESP
字符串是否正确。如果没有其他问题,我可能需要确认一下这一点,以及设置接收器可以看到的操作的正确方法。
所以,到目前为止,这就是我拥有的...

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);

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<Button>(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<TextView>(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<TextView>(Resource.Id.status);
txtView.Text = intent.GetStringExtra(TestIntentService.PARAM_OUT_MSG).ToString();
Toast.MakeText(context, "On Receive complete!", ToastLength.Short).Show();
}
}
}
}
- 我做错了吗?我离正确还差多远呢?我认为我很接近了,但如果我错了,请务必告诉我...
- 如果是这样的话,发送和接收广播的正确方法是什么?
