我的代码写的比较乱，不好意思拿上来，但是我个人亲测过，还是可以实现快进快退的功能的。截取一部分供大家参考

simpleExoPlayerView.setOnTouchListener(new View.OnTouchListener() {            @Override            public boolean onTouch(View view, MotionEvent event) {                int action = event.getAction();                switch (action) {                    case MotionEvent.ACTION_DOWN:                        x = (int) event.getRawX();                        y = (int) event.getRawY();                        break;                    case MotionEvent.ACTION_UP:                        int upX = (int) event.getRawX();                        int upY = (int) event.getRawY();                        int disX = upX - x;                        int dixY = upY - y;                        if (Math.abs(disX) > Math.abs(dixY) && Math.abs(disX) > 10) {                            long fastLength = unitLength * disX;                            long currentLength = (simpleExoPlayer.getCurrentPosition() + fastLength);                            if (currentLength >= 0 && currentLength <= totalTime) {                                simpleExoPlayer.seekTo(currentLength);                            }                        }                        break;                }                return true;            }        });

private long unitLength;    private long totalTime;        @Override    public void onPlayerStateChanged(boolean playWhenReady, int playbackState) {        switch (playbackState) {            case PlaybackState.STATE_PLAYING:                // 获取总时长，然后计算                if (totalTime == 0) {                    totalTime = (simpleExoPlayer.getDuration());                    int width = MobileScreenUtils.getScreenWidth(mContext);                    if (totalTime < width) {                        unitLength = (totalTime % width);                    } else {                        unitLength = (totalTime / width);                    }                    LogUtils.e("总时长是:" + totalTime + "--" + width);                }                initPlayVideo();                break;            case PlaybackState.STATE_BUFFERING:                System.out.println("播放状态: 缓存完成 playing");                break;            case PlaybackState.STATE_CONNECTING:                System.out.println("播放状态: 连接 CONNECTING");                break;            case PlaybackState.STATE_ERROR://错误                System.out.println("播放状态: 错误 STATE_ERROR");                break;            case PlaybackState.STATE_FAST_FORWARDING:                System.out.println("播放状态: 快速传递");                pausePlay();//暂停播放                break;            case PlaybackState.STATE_NONE:                System.out.println("播放状态: 无 STATE_NONE");                break;            case PlaybackState.STATE_PAUSED:                System.out.println("播放状态: 暂停 PAUSED");                break;            case PlaybackState.STATE_REWINDING:                System.out.println("播放状态: 倒回 REWINDING");                break;            case PlaybackState.STATE_SKIPPING_TO_NEXT:                System.out.println("播放状态: 跳到下一个");                break;            case PlaybackState.STATE_SKIPPING_TO_PREVIOUS:                System.out.println("播放状态: 跳到上一个");                break;            case PlaybackState.STATE_SKIPPING_TO_QUEUE_ITEM:                System.out.println("播放状态: 跳到指定的Item");                break;            case PlaybackState.STATE_STOPPED:                System.out.println("播放状态: 停止的 STATE_STOPPED");                break;        }    }

这个方法是实现了Player.EventListener接口实现的。unitLength是根据屏幕宽度和视频总时长来计算出来的。
