半年前写了个音乐播放器，仿的是多米的UI界面
之前发表在eoe社区，今天也发到csdn上来
不罗嗦，先上效果图：
下面简单介绍下代码：
MusicPlayer 播放音乐的核心类，该类有以下成员变量
private final static String TAG = "MusicPlayer";
private final String BROCAST_NAME = "com.genius.musicplay.brocast";
private MediaPlayer mMediaPlayer; // 播放器对象
private List<MusicData> mMusicFileList; // 音乐文件列表
private int mCurPlayIndex; // 当前播放索引
private int mPlayState; // 播放器状态
private int mPLayMode; // 歌曲播放模式
private Random mRandom;
private Context mContext;
其实该类就是将MediaPlayer做了一层封装，提供出一些播放音乐的相关操作如播放，暂停，上一曲，下一曲等等
MusicService 是播放音乐的服务继承自service，MediaPlayer作为它的成员变量
所以对MediaPlayer的操作就委托给了MusicService
ServiceManager，管理服务的对象，采用AIDL接口方式实现远程操作，对AIDL熟悉的童鞋你懂得
private final static String TAG = "ServiceManager";
private final static String SERVICE_NAME = "com.genius.service.musicservices";
private Boolean mConnectComplete;
private ServiceConnection mServiceConnection;
private MusicConnect mMusicConnect;
private IOnServiceConnectComplete mIOnServiceConnectComplete;
private Context mContext;
MusicConnect就是AIDL接口对象
MusicData音乐歌曲的信息，由于要在AIDL接口传递，所以需要实现Parcelable接口
public class MusicData implements Parcelable{
public final static String KEY_MUSIC_DATA = "MusicData";
private final static String KEY_MUSIC_NAME = "MusicName";
private final static String KEY_MUSIC_TIME = "MusicTime";
private final static String KEY_MUSIC_PATH = "MusicPath";
private final static String KEY_MUSIC_ARITST = "MusicAritst";
public String mMusicName;
public int mMusicTime;
public String mMusicPath;
public String mMusicAritst;
public MusicData()
{
mMusicName = "";
mMusicTime = 0;
mMusicPath = "";
mMusicAritst = "";
}
@Override
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
// TODO Auto-generated method stub
Bundle mBundle=new Bundle();
mBundle.putString(KEY_MUSIC_NAME, mMusicName);
mBundle.putInt(KEY_MUSIC_TIME, mMusicTime);
mBundle.putString(KEY_MUSIC_PATH, mMusicPath);
mBundle.putString(KEY_MUSIC_ARITST, mMusicAritst);
dest.writeBundle(mBundle);
}
public static final Parcelable.Creator<MusicData> CREATOR = new Parcelable.Creator<MusicData>()
{
@Override
public MusicData createFromParcel(Parcel source) {
// TODO Auto-generated method stub
MusicData Data = new MusicData();
Bundle mBundle=new Bundle();
mBundle = source.readBundle();
Data.mMusicName = mBundle.getString(KEY_MUSIC_NAME);
Data.mMusicTime = mBundle.getInt(KEY_MUSIC_TIME);
Data.mMusicPath = mBundle.getString(KEY_MUSIC_PATH);
Data.mMusicAritst = mBundle.getString(KEY_MUSIC_ARITST);
return Data;
}
@Override
public MusicData[] newArray(int size) {
// TODO Auto-generated method stub
return new MusicData[size];
}
};
}
音乐播放模式类
public class MusicPlayMode {
public static final int MPM_SINGLE_LOOP_PLAY = 0; // 单曲循环
public static final int MPM_ORDER_PLAY = 1; // 顺序播放
public static final int MPM_LIST_LOOP_PLAY = 2; // 列表循环
public static final int MPM_RANDOM_PLAY = 3; // 随即播放
}
音乐播放状态类
public class MusicPlayState {
public static final int MPS_NOFILE = -1; // 无音乐文件
public static final int MPS_INVALID = 0; // 当前音乐文件无效
public static final int MPS_PREPARE = 1; // 准备就绪
public static final int MPS_PLAYING = 2; // 播放中
public static final int MPS_PAUSE = 3; // 暂停
public static final String PLAY_STATE_NAME = "PLAY_STATE_NAME";
public static final String PLAY_MUSIC_INDEX = "PLAY_MUSIC_INDEX";
public static final String MUSIC_INVALID = "MUSIC_INVALID";
public static final String MUSIC_PREPARE = "MUSIC_PREPARE";
public static final String MUSIC_PLAY = "MUSIC_PLAY";
public static final String MUSIC_PAUSE = "MUSIC_PAUSE";
public static final String MUSIC_STOP = "MUSIC_STOP";
}
MusicPlayActivity，应用程序主界面，该类代码也最多，不过里面细分了几个内部类，如UIManager里面就包含了很多控件对象以及对它们的操作
private final static String TAG = "MusicPlayActivity";
private final String BROCAST_NAME = "com.genius.musicplay.brocast";
private final static int REFRESH_PROGRESS_EVENT = 0x100;
private final static int ABOUT_DIALOG_ID = 1;
private Handler mHandler;
private UIManager mUIManager;
private ServiceManager mServiceManager; // 本地服务管理
private MusicTimer mMusicTimer; // 检测歌曲进度的定时器
private MusicPlayStateBrocast mPlayStateBrocast; // 音乐播放状态的广播接收器
private SDStateBrocast mSDStateBrocast; // SD卡变化接收器
private List<MusicData> m_MusicFileList; // 音乐列表
private ListViewAdapter mListViewAdapter;
private boolean mIsSdExist = false; // SD卡是否存在
private boolean mIsHaveData = false; // 是否有音乐文件
private int mCurMusicTotalTime = 0;
private int mCurPlayMode = MusicPlayMode.MPM_LIST_LOOP_PLAY;
MySlidingDrawer，自定义抽屉控件，属于UIManager的一部分
MusicTimer，用于定时获取歌曲进度的定时器
其它的东东就不多说了，有兴趣的童鞋自个儿下代码（有注释）看吧
