I have an Activity that starts and binds to a service. It sends an intent with a List of data and the service is responsible for periodically updating that data. This is done in the handleIntent (Intent) method. What I want to do is send the updated data back to the activity. Both the activity and the service are in the same application. How can I "listen" for requests from my service? Do I have to use a Messenger and/or Broadcast Receiver? what's the cleanest, easiest, most efficient way of doing this? Thanks.

推荐答案

我建议您检查 EventBus .它可以让您发送本地广播接收器之类的事件.从活动中，您可以监听特定事件并显示结果.您甚至还可以使用接口从服务中获取回调.

I suggest you check EventBus. it will allow you to send events like local broadcast receiver. And from that in activity you can listen specific event and display result. you can even use interface to get callback from service also.

没有任何库，您可以使用LocalBroadcastManager来实现. http://developer.android.com/reference/android/support/v4/content/LocalBroadcastManager.html

Without any library you can achieve this with LocalBroadcastManager. http://developer.android.com/reference/android/support/v4/content/LocalBroadcastManager.html
