1，創建MusicPlayService繼承Service

public class MusicPlayService extends Service{ } |
2, 在MusicPlayService中創建內部類Mybinder繼承Binder

|
public final class Mybinder extends Binder{ public MusicPlayService getService() { return MusicPlayService.this; } } |
3, 重寫onBinder()方法，反回內部類Mybinder實例對象
|

|
public IBinder onBind(Intent arg0) { // TODO Auto-generated method stub return new Mybinder(); } |
4，重寫onCreate()

public void onCreate() { // TODO Auto-generated method stub Toast.makeText(this, "MusicSevice onCreate()" , Toast.LENGTH_SHORT).show(); Log.e("test", "--->onCreate()"); //musicplay=BackgroundMusicPlay.getBackgroundMusicPlay(this); super.onCreate(); } |
5，在activity中綁定service

MusicPlayService service;//聲明服務對象 //綁定服務Intent intent2=new Intent(ShorMusicPlay.this, MusicPlayService.class);bindService(intent2, conn, BIND_AUTO_CREATE);//調用服務，通過第6步中的 service=((Mybinder)arg1).getService();得到實例對象service.playMusic();//playMusic可自行在MusicPlayService中添加 |
6，在ServiceConnection的onServiceConnected得到MusicPlayService的實例對象

private ServiceConnection conn=new ServiceConnection() { @Override public void onServiceConnected(ComponentName arg0, IBinder arg1) { // TODO Auto-generated method stub Log.e("test", " on Service Connected"); service=((Mybinder)arg1).getService();//得到MusicPlayService實例對象 } @Override public void onServiceDisconnected(ComponentName arg0) { // TODO Auto-generated method stub Log.e("test", " on Service Disconnected"); } }; |
7，在onDestroy()方法中解除綁定

protected void onDestroy() { // TODO Auto-generated method stub super.onDestroy(); unbindService(conn); } |
