//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) {            }        });    }
