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

public void play(){
        player.reset();
        try{
            player.setDataSource(musics.get(binder.getCurMusicIndex()));
            player.prepare();
            player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                @Override
                public void onPrepared(MediaPlayer mediaPlayer) {
                    player.start();
                }
            });
            player.seekTo(binder.getPausePosition());
            binder.setTotalMusicTime(player.getDuration());
        }catch (IOException e){
            e.printStackTrace();
        }
    }

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

if (curMusicIndex<0) {
            binder.setCurMusicIndex(musics.size() - 1);
            binder.setPausePosition(0);
            play();
        }else{
            binder.setCurMusicIndex(curMusicIndex);
            binder.setPausePosition(0);
            play();
        }

实现进度条以及进度条快进

handler = new Handler(){
            @Override
            public void handleMessage(Message msg) {
                String playTime = msg.getData().getString("playTime");
                String totalTime = msg.getData().getString("totalTime");
                textCur.setText(playTime);
                textTotal.setText(totalTime);
            }
        }

实现音乐目录的遍历

private void initLiseView(){
        String path = Environment.getExternalStorageDirectory().getAbsolutePath()+"/music/";
        File mp3dir = new File(path);
        if (mp3dir.isDirectory()){
            File[] files = mp3dir.listFiles();
            for(File f:files){
                musics.add(f.getAbsolutePath());
                simpleMusics.add(f.getName());
            }
        }
        binder.setMusics(musics);
        binder.setSimpleMusics(simpleMusics);
    }
