回收器适配器中的 2 视图支架

Question

我是 android 开发的新手。很抱歉，如果这是一个无用的问题。我有 RecyclerView，就像我想在 RecyclerView 中显示来自 Firebase 的图像和视频。

我有两个ViewHolder。我想要的是，适配器检查 post "type"。如果
1)"type"=photo。我要充气 PhotoViewHolder.
2) 如果 "type"= 视频我想膨胀 VideoHolder.

我怎样才能做到这一点？。请帮帮我！

我在谷歌上搜索了几个小时，我得到了这段代码，它只会膨胀 VideoHolder

@NonNull
@Override
public RecyclerView.ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
    //findViewById...
    mContext = parent.getContext();
    switch (viewType) {
        case VIDEO_TYPE:
            View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.video_type, parent, false);
            return new VideoHolder(v);
        case IMAGE_TYPE:
            View i = LayoutInflater.from(parent.getContext()).inflate(R.layout.main_list, parent, false);
            return new PhotoHolder(i);

    }
    return null;
}
@Override
public void onBindViewHolder(@NonNull final RecyclerView.ViewHolder holder, final int position) {
    mHolder = holder;
    photo = moviesList.get(position);
    //  final VideoHolder viewHolder2 = (VideoHolder)holder;
    int viewType = getItemViewType(position);
    switch ( viewType ) {
        case IMAGE_TYPE:
            PhotoHolder photoview = (PhotoHolder) holder;
            final ImageLoader imageLoader =  ImageLoader.getInstance();
            imageLoader.displayImage(getItem(position).getImage_path(),photoview.image);
            break;
        case VIDEO_TYPE:
            final VideoHolder viewHolder2 = (VideoHolder)holder;
            //viewHolder2.users = new StringBuilder();
            viewHolder2.bind(Uri.parse(photo.getImage_path()),moviesList);
            break;
    }


}

@Override
public int getItemCount() {
    return moviesList.size();
}
public Photo getItem(int position) {
    return moviesList.get(position);
}
@Override
public int getItemViewType ( int position ) {
    int viewType;
    if if (moviesList.get(position).getType().equals("Photo")) {
        viewType = IMAGE_TYPE;
    } else{
        viewType = VIDEO_TYPE;
    }
    return viewType;
}

Answer 1

将 .equals() 更改为 .contains()

 @Override
public int getItemViewType ( int position ) {
    int viewType;
    if (moviesList.get(position).getType_post().contains("Photo")) {
        viewType = IMAGE_TYPE;
    } else{
        viewType = VIDEO_TYPE;
    }
    return viewType;
}
