为自己打造通用的音乐播放代代码库
1.写这边文章的目的：从实习到现在两年的时间，在这段时间内学习和播放器打交道的时间算是比较多然鹅在做新的项目的时候居然发现自己还是必须重新再写一遍以前的代码，重复的干同样的一件事。感觉这样十分浪费时间，希望能封装一个比较灵活的播放器代码以后只需要集成添加对应的业务逻辑即可。因此参照着以前项目上视频播放器的东西。想要自己封装一个比较通俗易用的音视频播放模块。希望这个模块能够达到以下的功能。
a.整个模块不接触具体的业务逻辑，能够根据具体的项目需求实现定制化的功能
b.能实现播放器的任意切换（很有可能有的项目使用MediaPlayer有的使用IJK）
c.对于音频播放器而言能够定制自己的notification，能够在现在的设计下进行交互处理。
2.模块设计：
具体介绍：
AbsMusicPlayerService：后台音乐播放服务，持有逻辑控制器controller和InotificationStrage并且实现了音乐播放的事件监听IMusicPlayerEvents。
AbsPlayerController：封装了播放器相关的逻辑，具体的特殊业务逻辑需要自己在实现类中进行处理。
MusicBroadcastReceive:主要是接收notification的PendingIntent发送过来与音频相关的广播。
AbsNotification：根据不同的状态构建不同的notification通知。
AndroidMusicPlayer 实现了IMusicPlayer:音乐播放器接口抽象，封装了mediaPlayer实现音乐播放。
先看看效果图：
使用：
（1）.在自己项目build.gradle中添加 implementation'com.txl.player:player:1.0.1'
（2）.继承AbsPlayerController实现自己的业务逻辑，在具体的实现中决定使用什么类型的播放器，和如何创建对应的nitification。

@Override
public Notification createSeekNotification(long pos) {
return null;
}
@Override

}
（3）实现自己的音频播放服务，并将它注册在manifest
public class AndroidMusicPlayerService extends AbsMusicPlayerService {
@Override
protected IMusicPlayerController createPlayerController() {
return new DemoMusicPlayerController(this);
}
@Override
public boolean
onReceiveControllerCommand(String action, Object... o) {
notificationManager.createOtherNotification(action,o);
return false;
}
}
（4）在需用用到音频播放器的地方实现绑定对应的服务，获取对应的播放控制器实现逻辑控制。
public class MainActivity extends AppCompatActivity implements IMusicPlayer.IMusicPlayerEvents{
protected final String TAG = getClass().getSimpleName();
IMusicPlayerController musicPlayerController;
/**

initView();
Intent intent = new Intent();
intent.setClass(this,AndroidMusicPlayerService.class);
serviceConnection = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName name, IBinder service) {
if(service instanceof IMusicPlayerController){
musicPlayerController = (IMusicPlayerController) service;
musicPlayerController.addPlayerEventListener(MainActivity.this);
//在使用之前需要初始化一下
musicPlayerController.init(null);
}else {
Log.e(TAG,"serviceConnection musicPlayerController init error unBind service");
}
}
@Override
public void onServiceDisconnected(ComponentName name) {
musicPlayerController.removePlayerEventListener(MainActivity.this);
}
};
bindService(intent, serviceConnection,Context.BIND_AUTO_CREATE);

musicPlayerController.seek(pos);
}
}
});
}
private void togglePlayerUi(boolean isPlay){
if(isPlay){
imageToggleMusic.setImageResource( R.drawable.image_pause );
}else {
imageToggleMusic.setImageResource( R.drawable.image_play );
}
}
@Override
protected void onDestroy() {
super.onDestroy();
unbindService(serviceConnection);
musicPlayerController = null;
}
private void changePageUi(MusicData musicData){
tvMusicName.setText(musicData.getMusicName());
imageMusicAuthorIcon.setImageResource(musicData.getPlayerUserIconResId());
}
@Override
public boolean onError(IMusicPlayer xmp, int code, String msg) {
togglePlayerUi(false);
return false;
}
@Override
public boolean onPrepared(IMusicPlayer player) {
return false;
}
@Override
public boolean onSeekComplete(IMusicPlayer player, long pos) {
return false;
}
@Override
public boolean onComplete(IMusicPlayer player) {
togglePlayerUi(false);
return false;
}
@Override
public boolean onBuffering(IMusicPlayer player, boolean buffering, float percentage) {
return false;
}
@Override
public boolean onProgress(IMusicPlayer player, long pos, long total) {
if(total != 0){
duration = total/1000;
seekBar.setMax((int) (total/1000));
seekBar.setProgress((int) (pos/1000));
}else {
duration = musicPlayerController.getDuration();
}
return false;
}
@Override
public void onMusicServiceDestroy(IMusicPlayer player) {
}
@Override
public boolean onPlay(IMusicPlayer player) {
togglePlayerUi(true);
return false;
}
@Override
public boolean onPause(IMusicPlayer player) {
togglePlayerUi(false);
return false;
}
@Override
public boolean onStop(IMusicPlayer player) {
togglePlayerUi(false);
return false;
}
@Override
public boolean onReceiveControllerCommand(String action, Object... o) {
switch (action){
case DemoMusicPlayerController.ACTION_PLAY_NEXT:
case DemoMusicPlayerController.ACTION_PLAY_PRE:
if(o != null && o.length > 0){
MusicData musicData = (MusicData) o[0];
changePageUi(musicData);
}
break;
default:
break;
}
return false;
}
@Override
public void onBackPressed() {
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addCategory(Intent.CATEGORY_HOME);
startActivity(intent);
}
}
这样一款简单的音乐播放器就实现了。
最后附上demo地址。https://github.com/xiaolutang/AndroidPlayer
2019第的以一个flag：继续完成封装通用的视频播放代码。还有，2018年末在鸿洋大神的wanandroid上面看了许多的2018的年度总结，希望2019我也要有一个漂亮的年度总计。
