Android基础教程(五)之 ------ Andorid播放音频文件服务（MP3）

1.在raw目录放一个mp3文件：test.mp3;

2.建一个MediaPlay的Service文件MusicService.java

public class MusicService extends Service
{
//MediaPlayer对象
private MediaPlayer player;

public IBinder onBind(Intent arg0)
{
  return null;
}

public void onStart(Intent intent, int startId)
{
  super.onStart(intent, startId);
  //这里可以理解为装载音乐文件
  player = MediaPlayer.create(this, R.raw.test);
  //开始播放
  player.start();
}

public void onDestroy()
{
  super.onDestroy();
  //停止音乐-停止Service
  player.stop();
}

}

3.主文件

public void onCreate(Bundle savedInstanceState)
{
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);
 
  //从main.xml布局中获得Button对象
  Button button_start = (Button)findViewById(R.id.start);
  Button button_stop = (Button)findViewById(R.id.stop);
  //设置按钮（Button）监听
  button_start.setOnClickListener(start);
        button_stop.setOnClickListener(stop);

}

//开始按钮
private OnClickListener start = new OnClickListener()
    {
        public void onClick(View v)
        {  
         //开启Service
            startService(new Intent("com.yarin.Android.MUSIC"));
        }
    };
   //停止按钮
    private OnClickListener stop = new OnClickListener()
    {
        public void onClick(View v)
        {
         //停止Service
            stopService(new Intent("com.yarin.Android.MUSIC"));      
        }
    };
