我是新来的Andr​​oid。我创建了Media Player的服务，以便它能够持续播放歌曲，即使我关闭应用程序。我创建活动媒体播放器，它是有一个像播放，暂停，下一个，previous，搜索栏的所有功能，还包括oncompletionlistener。所有做工精良。但现在我想，所​​有应该由服务来管理。

I am new to Android. I am creating service for Media Player so that it can continue to play song even if i close the application. I have created activity for Media Player and it is having all the functionality like play , pause , next , previous , seekbar and also includes oncompletionlistener . All works excellent. But Now i want that all should be managed by service.

我已经创建的MyService类：

I have Created MyService Class :

public class MyService extends Service {

    public static MediaPlayer mp;

    @Override
    public IBinder onBind(Intent intent) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public void onCreate() {
        mp = new MediaPlayer();     
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {  
        return START_STICKY;
    }

但在我的玩家活动我创建的ArrayList为的SongList从中我正在currentsongIndex并通过它我维护所有的功能，例如接下来，previous所有。现在的服务如何获得的SongList这是还需要在我的活动？我应该在哪里创建MediaPlayer对象是指在服务或活动??

But in my player activity i have created ArrayList for Songlist from which i am taking currentsongIndex and through it i am maintaining all the functionality like next , previous and all.. Now in service how do i get songlist which is also required in my activity ?? Where should i create MediaPlayer object mean in service or activity ??

推荐答案

您是在正确的轨道上。我已经适应了从SDK样本;我这是怎么做到这一点，它的伟大工程。 从你的ArrayList（在你的活动不会从服务）的调用。

You are on the right track. I have adapted from the SDK Samples; this is how I do it and it works great. From your ArrayList (in your activity NOT from the Service) call

onListItemClick

和启动意图启动音乐服务：

and start an intent that starts the music service:

startService(new Intent(MusicService.ACTION_PLAY));

在你的清单，你将需要添加：

In your manifest you will need to add:

 <intent-filter>
            <action android:name="com.blah.blah.action.PLAY" />
           <xxx xxx> 
 </intent-filter>

当然在你的音乐服务，你需要接受的意图：

And of course in your Music Service you need to receive the Intent:

public int onStartCommand(Intent intent, int flags, int startId) {
    String action = intent.getAction();
    if (action.equals(ACTION_PLAY))
        processPlayRequest();
  }

一定要添加意图的跳跃，后退，停止等。 让我知道如果这有助于。

Be sure to add Intents for skip, rewind, stop etc. Let me know if this helps.
