GL音乐播放器--代码实现

今天，我就把我的musicService类贴出来，这个是播放器能运行的主要机制。由于昨天才将博客搬家过来，其实现在我的软件项目已经完成，本打算边写项目边写博客，看样子是做不到了，接下来的几篇博客会将我的主要功能代码贴出来，如果大家想直接看代码，就去我的资源那去下载，如果想看看具体解释，讲解，就继续跟我的博客，因为快开学的缘故，我会尽快完成。

话不多说，上代码：

 

 

首先是 MusicService类主要获取文件状态，这是我总的，你可以有选择的看，里面好多我会在后面的博客里提到

package com.genius.service;

import java.util.List;

import com.genius.aidl.MusicConnect;
import com.genius.aidl.MusicConnect.Stub;

public class MusicService extends Service{

	}

	@Override

        registerReceiver(mSDStateBrocast, intentFilter);
		
	}

			}
		}

		@Override

		}


	};
	
	
	//自定义的BroadcastReceiver，负责监听从Service传回来的广播 
	class  SDStateBrocast extends BroadcastReceiver
	{

		@Override
		public void onReceive(Context context, Intent intent) {
			// TODO Auto-generated method stub
			 String action = intent.getAction(); 
			  if (action.equals(Intent.ACTION_MEDIA_MOUNTED))//插入SD卡并且已正确安装（识别）

			  }else if (action.equals(Intent.ACTION_MEDIA_UNMOUNTED))//SD卡存在，但是还没有被挂载 
			  {
				 
			  }else if (Intent.ACTION_MEDIA_SCANNER_FINISHED.equals(action))//已经扫描SD的目录

			  }else if (Intent.ACTION_MEDIA_EJECT.equals(action))//已拔掉SD卡
			  {
				  m_mMusicPlayer.exit();

		}
	}
}

接下来是MusicPlayer，主要控制播放状态模式改变对应的响应
