我想出的解决方案是这样的：

首先,将搜索栏的最大进度设置为视频的持续时间

videoView.setOnPreparedListener(new OnPreparedListener() {

        @Override
        public void onPrepared(MediaPlayer mp) {

            seekBar.setMax(videoView.getDuration());
            seekBar.postDelayed(onEverySecond,1000);
        }
    });

这个runnable将继续更新进度条：

private Runnable onEverySecond=new Runnable() {

    @Override
    public void run() {

        if(seekBar != null) {
            seekBar.setProgress(videoView.getCurrentPosition());
        }

        if(videoView.isPlaying()) {
            seekBar.postDelayed(onEverySecond,1000);
        }

    }
};

然后,用于seekbar的setOnSeekBarChangeListener可以用于使用户在媒体上查找.通过使用fromUser布尔值,我们可以确定是否由于用户的交互或回调

seekBar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {
        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {
        }

        @Override
        public void onProgressChanged(SeekBar seekBar,int progress,boolean fromUser) {

            if(fromUser) {
                // this is when actually seekbar has been seeked to a new position
                videoView.seekTo(progress);
            }
        }
    });
