一、播放器截图

当某一首歌播放的时候使用绿色为他的底部，同时我这个音乐播放器支持进度条拖拽快进。

二、播放器关键代码

设置绑定功能

public int getPlayPosition() {
return playPosition;
}

public void setPlayPosition(int playPosition) {
this.playPosition = playPosition;
}

public MyBinder(MusicService musicService) {
this.musicService = musicService;
}

public List<String> getSimpleMusics() {
return simpleMusics;
}

public void setSimpleMusics(List<String> simpleMusics) {
this.simpleMusics = simpleMusics;
}

public void setMusicService(MusicService musicService) {
this.musicService = musicService;
}

public boolean isPause() {
return isPause;
}

public void setPause(boolean pause) {
isPause = pause;
}

public MusicService getMusicService() {
return musicService;
}

public List<String> getMusics() {
return musics;
}

public void setMusics(List<String> musics) {
this.musics = musics;
}

public int getCurMusicIndex() {
return curMusicIndex;
}

public void setCurMusicIndex(int curMusicIndex) {
this.curMusicIndex = curMusicIndex;
}

public int getPausePosition() {
return pausePosition;
}

public void setPausePosition(int pausePosition) {
this.pausePosition = pausePosition;
}

public int getTotalMusicTime() {
return totalMusicTime;
}

public void setTotalMusicTime(int totalMusicTime) {
this.totalMusicTime = totalMusicTime;
}

播放功能实现

1 public void play(){
2         player.reset();
3         try{
4             player.setDataSource(musics.get(binder.getCurMusicIndex()));
5             player.prepare();
6             player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
7                 @Override
8                 public void onPrepared(MediaPlayer mediaPlayer) {
9                     player.start();
10                 }
11             });
12             player.seekTo(binder.getPausePosition());
13             binder.setTotalMusicTime(player.getDuration());
14         }catch (IOException e){
15             e.printStackTrace();
16         }
17     }

暂停功能

if (player.isPlaying()){
player.pause();
binder.setPause(true);
binder.setPausePosition(player.getCurrentPosition());
}

下一首功能

if (curMusicIndex >=musics.size()){
binder.setCurMusicIndex(0);
binder.setPausePosition(0);
play();
}
else{
binder.setCurMusicIndex(curMusicIndex);
binder.setPausePosition(0);
play();
}

上一首功能

1 if (curMusicIndex<0) {
2             binder.setCurMusicIndex(musics.size() - 1);
3             binder.setPausePosition(0);
4             play();
5         }else{
6             binder.setCurMusicIndex(curMusicIndex);
7             binder.setPausePosition(0);
8             play();
9         }

实现进度条以及进度条快进

1 handler = new Handler(){
2             @Override
3             public void handleMessage(Message msg) {
4                 String playTime = msg.getData().getString("playTime");
5                 String totalTime = msg.getData().getString("totalTime");
6                 textCur.setText(playTime);
7                 textTotal.setText(totalTime);
8             }
9         }

实现音乐目录的遍历

1 private void initLiseView(){
2         String path = Environment.getExternalStorageDirectory().getAbsolutePath()+"/music/";
3         File mp3dir = new File(path);
4         if (mp3dir.isDirectory()){
5             File[] files = mp3dir.listFiles();
6             for(File f:files){
7                 musics.add(f.getAbsolutePath());
8                 simpleMusics.add(f.getName());
9             }
10         }
11         binder.setMusics(musics);
12         binder.setSimpleMusics(simpleMusics);
13     }
