Services 后台播放音乐

1.界面主要代码段:

private OnClickListener startIt = new OnClickListener() {
		public void onClick(View v) {
			startService(new Intent(
					"com.iceskysl.PlayService.START_AUDIO_SERVICE"));
		}
	};

	private OnClickListener stopIt = new OnClickListener() {
		public void onClick(View v) {
			stopService(new Intent(
					"com.iceskysl.PlayService.START_AUDIO_SERVICE"));
			finish();
		}
	};

2.Service类代码:

public class Music extends Service {
    private MediaPlayer player;

	@Override
	public IBinder onBind(Intent intent) {
		// TODO Auto-generated method stub
		return null;
	}
	
	public void onStart(Intent intent, int startId) {       
        super.onStart(intent, startId);
        player = MediaPlayer.create(this, R.raw.gequ);
        player.start();
    }
   
    public void onDestroy() {
        super.onDestroy();
        player.stop();
        player.release();
    }

}

3.配置文件中申明:

<application android:icon="@drawable/icon" android:label="@string/app_name">
		<activity android:name=".PlayService" android:label="@string/app_name">
			<intent-filter>
				<action android:name="android.intent.action.MAIN" />
				<category android:name="android.intent.category.LAUNCHER" />
			</intent-filter>
		</activity>
		<service android:name=".Music">
			<intent-filter>
				<action android:name="com.iceskysl.PlayService.START_AUDIO_SERVICE" />
				<category android:name="android.intent.category.default" />
			</intent-filter>
		</service>
	</application>
