android - 当我回到上一个 View ViewPager2 时，ExoPlayer 不播放 onViewRecycled

Question

我正在使用带有回收器 View 适配器的 ViewPager2 并设置以下内容，如下所示
当我滑动屏幕并更改索引时，它对新索引的工作正常，但是当我转到上一个索引时，它不会播放任何视频，为什么？有什么建议？？
RecyclerViewAdapter.java

@Override
public void onViewDetachedFromWindow(@NonNull VideoPlayerViewHolder holder) {
    super.onViewDetachedFromWindow(holder);
    holder.pausePlayer();
    holder.releasePlayer();
}

@Override
public void onViewAttachedToWindow(@NonNull VideoPlayerViewHolder holder) {
    super.onViewAttachedToWindow(holder);
    holder.startPlayer();
}

  @Override
public void onViewRecycled(@NonNull VideoPlayerViewHolder holder) {
    super.onViewRecycled(holder);
    holder.startPlayer();
}


 @Override
public void onBindViewHolder(@NonNull VideoPlayerViewHolder holder, int position) {
    holder.setExoplayer(getItem(position).getUrl());
}

ViewHolderr.java

  public void startPlayer() {
    player.setPlayWhenReady(true);
    player.getPlaybackState();
}

public void pausePlayer() {
 
    player.setPlayWhenReady(false);
    player.getPlaybackState();
}


public void setExoplayer(String url) {
    player = new SimpleExoPlayer.Builder(itemView.getContext()).build();
    player.setRepeatMode(Player.REPEAT_MODE_ONE);
    dataSourceFactory = new DefaultDataSourceFactory(itemView.getContext(),"exo-player");
    mediaSource = new ProgressiveMediaSource.Factory(dataSourceFactory).createMediaSource(Uri.parse(url));
    player.prepare(mediaSource);
    playerView.setPlayer(player); //need to transfer
    player.seekTo(playbackPosition);
    player.addListener(this);
}

public void releasePlayer() {
    player.setPlayWhenReady(false);
    player.release();
    player.stop(true);
}

像这样附加 View 时设置 Exoplayer

@Override
public void onViewAttachedToWindow(@NonNull VideoPlayerViewHolder holder) {
    super.onViewAttachedToWindow(holder);
    holder.setExoplayer();
    holder.startPlayer();
}
