如何将数据从IntentService发送到Non-Activity类

Question

我有两个服务类。 一个是WebsocketService(extends Service)来管理Websocket related function ，一个是SocketMessageProcessing(extends IntentService)来process response Received in WebSocketService 。 从Non-Activity(SocketImpl)类我成功地能够将数据发送到WebsocketService 。 但是我在从SocketMessageProcessing类发送响应回SocketImpl类时遇到了麻烦。

//Common Class To send data to WebsocketService and Receive response from SocketMessageProcessing Service When Work Done. I am using this class as callback.
public class SocketImpl{

    private String json;
    private Context mContext;
    private WebServiceResponseListener mListener;

    public SocketImpl(Context context, String json, WebServiceResponseListener mListener){
    //Initilize variables
    }

    public void execute() {
        //Send request to websocket 
        WebSocketService.sendMessage(mAdapter.getContxet(), json);
    }

    public void onResponse(String resp, String tag) {
    //Here I would like to receive response from IntenService Class.
    }

}

//This class will perform Websocket related function and it will send response to SocketMessageProcessing once response received.
public class WebSocketService extends Service {
      ...

      private void processResponse(String message){
              Intent intent = new Intent(mContext, SocketMessageProcessing.class);
              intent.putExtra("DATA", message);
              mContext.startService(intent);
      }
}


//Intent service to Process the incoming websocket response, And Send response Back to Class Where Its originate(SocketImpl).
public class SocketMessageProcessing extends IntentService{

    @Override
    protected void onHandleIntent(Intent intent) {
        String json = intent.getStringExtra("DATA");
        //Process json and send data back to class from where request originate?
    }

}

以下我到目前为止尝试过的事情。

1. LocalBroadcastManager
   因为我想在Non-Activity类中接收响应，所以我不知道如何管理register并unregister BroadcastReceiver 。

2. 缓存SocketImpl对象并在SocketMessageProcessing获取该对象并尝试调用onResponse() 。 但我确实得到了"sending message to a handler on a dead thread"异常，所以认为这不是一个好主意。 因为onResponse方法执行许多与UI相关的操作。

任何帮助表示赞赏。 提前致谢！

您建议的选项＃1是标准方式。 而且您只需要一个上下文对象即可注册和取消注册

LocalBroadcastManager.getInstance(context).registerReceiver(...

我刚刚在我的应用程序中尝试了非Activity类（使用它需要的活动上下文）并且它工作正常。 我不确定你的意思

我不知道如何管理寄存器并取消注册BroadcastReceiver
