android 高仿多米音乐播放器 （有图有码有真相）

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

privatefinalstaticStringTAG="MusicPlayer";

privatefinalStringBROCAST_NAME="com.genius.musicplay.brocast";

privateMediaPlayermMediaPlayer;//播放器对象

privateList<MusicData>mMusicFileList;//音乐文件列表

privateintmCurPlayIndex;//当前播放索引

privateintmPlayState;//播放器状态

privateintmPLayMode;//歌曲播放模式

privateRandommRandom;

privateContextmContext;

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

privatefinalstaticStringTAG="ServiceManager";

privatefinalstaticStringSERVICE_NAME="com.genius.service.musicservices";

privateBooleanmConnectComplete;

privateServiceConnectionmServiceConnection;

privateMusicConnectmMusicConnect;

privateIOnServiceConnectCompletemIOnServiceConnectComplete;

privateContextmContext;

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

publicclassMusicDataimplementsParcelable{

publicfinalstaticStringKEY_MUSIC_DATA="MusicData";

privatefinalstaticStringKEY_MUSIC_NAME="MusicName";

privatefinalstaticStringKEY_MUSIC_TIME="MusicTime";

privatefinalstaticStringKEY_MUSIC_PATH="MusicPath";

privatefinalstaticStringKEY_MUSIC_ARITST="MusicAritst";

publicStringmMusicName;

publicintmMusicTime;

publicStringmMusicPath;

publicStringmMusicAritst;

publicMusicData()

{

mMusicName="";

mMusicTime=0;

mMusicPath="";

mMusicAritst="";

}

@Override

publicintdescribeContents(){

//TODOAuto-generatedmethodstub

return0;

}

@Override

publicvoidwriteToParcel(Parceldest,intflags){

//TODOAuto-generatedmethodstub

BundlemBundle=newBundle();

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);

}

publicstaticfinalParcelable.Creator<MusicData>CREATOR=newParcelable.Creator<MusicData>()

{

@Override

publicMusicDatacreateFromParcel(Parcelsource){

//TODOAuto-generatedmethodstub

MusicDataData=newMusicData();

BundlemBundle=newBundle();

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);

returnData;

}

@Override

publicMusicData[]newArray(intsize){

//TODOAuto-generatedmethodstub

returnnewMusicData[size];

}

};

}

音乐播放模式类

publicclassMusicPlayMode{

publicstaticfinalintMPM_SINGLE_LOOP_PLAY=0;//单曲循环

publicstaticfinalintMPM_ORDER_PLAY=1;//顺序播放

publicstaticfinalintMPM_LIST_LOOP_PLAY=2;//列表循环

publicstaticfinalintMPM_RANDOM_PLAY=3;//随即播放

}

音乐播放状态类

publicclassMusicPlayState{

publicstaticfinalintMPS_NOFILE=-1;//无音乐文件

publicstaticfinalintMPS_INVALID=0;//当前音乐文件无效

publicstaticfinalintMPS_PREPARE=1;//准备就绪

publicstaticfinalintMPS_PLAYING=2;//播放中

publicstaticfinalintMPS_PAUSE=3;//暂停

publicstaticfinalStringPLAY_STATE_NAME="PLAY_STATE_NAME";

publicstaticfinalStringPLAY_MUSIC_INDEX="PLAY_MUSIC_INDEX";

publicstaticfinalStringMUSIC_INVALID="MUSIC_INVALID";

publicstaticfinalStringMUSIC_PREPARE="MUSIC_PREPARE";

publicstaticfinalStringMUSIC_PLAY="MUSIC_PLAY";

publicstaticfinalStringMUSIC_PAUSE="MUSIC_PAUSE";

publicstaticfinalStringMUSIC_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

privatefinalstaticStringTAG="MusicPlayActivity";

privatefinalStringBROCAST_NAME="com.genius.musicplay.brocast";

privatefinalstaticintREFRESH_PROGRESS_EVENT=0x100;

privatefinalstaticintABOUT_DIALOG_ID=1;

privateHandlermHandler;

privateUIManagermUIManager;

privateServiceManagermServiceManager;//本地服务管理

privateMusicTimermMusicTimer;//检测歌曲进度的定时器

privateMusicPlayStateBrocastmPlayStateBrocast;//音乐播放状态的广播接收器

privateSDStateBrocastmSDStateBrocast;//SD卡变化接收器

privateList<MusicData>m_MusicFileList;//音乐列表

privateListViewAdaptermListViewAdapter;

privatebooleanmIsSdExist=false;//SD卡是否存在

privatebooleanmIsHaveData=false;//是否有音乐文件

privateintmCurMusicTotalTime=0;

privateintmCurPlayMode=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
