Android的广播从服务到活动 [英] Android Broadcast from Service To Activity

问题描述

我想从一个服务出来发送一个广播到活动中。我可以确认的广播从服务中发送，但活动不拿起任何东西。

I am trying to send a Broadcast from a service out to an Activity. I can verify the broadcast is sent from within the service, but the Activity doesn't pick up anything.

下面是相关服务code：

Here is the relevant service code:

   Intent i = new Intent(NEW_MESSAGE);  
   i.putExtra(FriendInfo.USERNAME, StringUtils.parseBareAddress(message.getFrom()));
   i.putExtra(FriendInfo.MESSAGE, message.getBody());
   i.putExtra("who", "1");
   sendBroadcast(i);

而在活动类接收端：

And the receiving end in the activity class:

public class newMessage extends BroadcastReceiver 
{
@Override
   public void onReceive(Context context, Intent intent) 
   {    
    String action = intent.getAction();
       if(action.equalsIgnoreCase(IMService.NEW_MESSAGE)){    
          Bundle extra = intent.getExtras();
          String username = extra.getString(FriendInfo.USERNAME);   
          String message = extra.getString(FriendInfo.MESSAGE);
          String who = extra.getString("who");
         }
   }
}

该BroadcastReceiver的是一个活动中定义的。我注册了接收器在活动的onCreate方法，而不是在清单文件。

The BroadcastReceiver is defined within an Activity. I am registering the receiver in the onCreate method of the Activity, not in the Manifest file.

我难倒，为什么它不会拍摄。任何事情。

I'm stumped as to why it won't rec. anything.

任何见解？

修改的
注册方式如下：

EDIT
Registering takes place as follows:

 registerReceiver(messageReceiver, new IntentFilter(IMService.NEW_MESSAGE));

在哪里的messageReceiver被定义为

Where "messageReceiver" is defined as

private newMessage messageReceiver = new newMessage();

IMService.NEW_MESSAGE仅仅是一个字符串=NewMessage作为

IMService.NEW_MESSAGE is merely a string = "NewMessage"

推荐答案

我不知道这是否是特定的设置，或者如果它是在普通的修复，但移动寄存器/注销到 onResume /的onPause _respectively _ ，而不是注册在的onCreate 解决了这个问题对我来说。

I'm not sure if it is specific to the set up, or if it is a fix in general, but moving the register/unregister to the onResume/onPause _respectively_ and not registering in the onCreate solved the problem for me.
