//同步seekbar与进度条时间
        private void updateSeekBar(){
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    if (player != null){
                        int mCurrentPosition = player.getCurrentPosition() / 1000;//获取player当前进度，毫秒表示
                        int total = player.getDuration() / 1000;//获取当前歌曲总时长
                        sb.setProgress(mCurrentPosition);//seekbar同步歌曲进度
                        sb.setMax(total);//seekbar设置总时长
                        tv_total.setText(calculateTime(total));
                        tv_current.setText(calculateTime(mCurrentPosition));
                    }
                    mHandler.postDelayed(this,1000);//延迟一秒运行线程
                }
            });
        }

//计算歌曲时间
        private String calculateTime(int time){
            int minute;
            int second;
            if (time >= 60){
                minute = time / 60;
                second = time % 60;
                return minute + ":" +second;
            }else if (time < 60){
                second = time;
                return "0:" + second;
            }
            return null;
        }
    3. //拉动seekbar，同步歌曲播放
            sb.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
                @Override
                public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
                    if (player != null && fromUser){
                        player.seekTo(progress * 1000);
                    }
                }
    
                @Override
                public void onStartTrackingTouch(SeekBar seekBar) {
    
                }
    
                @Override
                public void onStopTrackingTouch(SeekBar seekBar) {
    
                }
            });
        }参考
