当使用不同的viewholders时，RecyclerView不能顺畅滚动

我正在创建一个聊天应用程序，根据收到的消息类型，该应用程序将具有不同的布局类型。每个视图持有者都有自己的布局和实现。该应用程序工作正常，但在滚动时会滞后，尤其是在布局类型更改时。

@Override public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) { final int itemType = getItemViewType(position); switch (itemType) { case Const.CHAT_NOTIFICATION_TYPE_NOTIFY: ((NotifyViewHolder) holder).bindData(position); break; case VIEW_TYPE_DATE_HEADER: ((DefaultDateHeaderViewHolder) holder).bindData(position); break; case VIEW_TYPE_TEXT_MESSAGE: ((OutgoingViewHolder) holder).bindData(position); break; case -VIEW_TYPE_TEXT_MESSAGE: ((IncomingViewHolder) holder).bindData(position); break; case VIEW_TYPE_IMAGE_MESSAGE: ((OutgoingImageViewHolder) holder).bindData(position); break; case -VIEW_TYPE_IMAGE_MESSAGE: ((IncomingImageViewHolder) holder).bindData(position); break; case VIEW_TYPE_ATTACHMENT: ((OutgoingAttachmentViewHolder) holder).bindData(position); break; case -VIEW_TYPE_ATTACHMENT: ((IncomingAttachmentViewHolder) holder).bindData(position); break; } throw new IllegalStateException("Wrong message view type. Please, report this issue on GitHub with full stacktrace in description."); }

@Override public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { View row; switch (viewType) { case Const.CHAT_NOTIFICATION_TYPE_NOTIFY: row = LayoutInflater.from(context).inflate(R.layout.notify_bubble, parent, false); return new NotifyViewHolder(row); case VIEW_TYPE_DATE_HEADER: row = LayoutInflater.from(context).inflate(R.layout.item_date_header, parent, false); return new NotifyViewHolder(row); case VIEW_TYPE_TEXT_MESSAGE: row = LayoutInflater.from(context).inflate(R.layout.outgoing_bubble, parent, false); return new OutgoingViewHolder(row); case -VIEW_TYPE_TEXT_MESSAGE: row = LayoutInflater.from(context).inflate(R.layout.incoming_bubble, parent, false); return new IncomingViewHolder(row); case VIEW_TYPE_IMAGE_MESSAGE: row = LayoutInflater.from(context).inflate(R.layout.item_outcoming_image_message, parent, false); return new OutgoingImageViewHolder(row); case -VIEW_TYPE_IMAGE_MESSAGE: row = LayoutInflater.from(context).inflate(R.layout.item_incoming_image_message, parent, false); return new IncomingImageViewHolder(row); case VIEW_TYPE_ATTACHMENT: row = LayoutInflater.from(context).inflate(R.layout.item_outcoming_attachment, parent, false); return new OutgoingAttachmentViewHolder(row); case -VIEW_TYPE_ATTACHMENT: row = LayoutInflater.from(context).inflate(R.layout.item_incoming_attachment, parent, false); return new IncomingAttachmentViewHolder(row); }

return null;

}

有没有办法实现一个平滑的滚动布局
