android exoplayer实现左右滑动屏幕快进快退

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。
