当RecyclerView为空时显示单独视图(image+text)

public class EmptyViewHolder extends RecyclerView.ViewHolder {
    private ImageView imageView;
    private TextView textView;

    public EmptyViewHolder(View itemView) {
        super(itemView);
        imageView = itemView.findViewById(R.id.empty_image);
        textView = itemView.findViewById(R.id.empty_text);
    }

    public void bindData(int imageResId, String text) {
        imageView.setImageResource(imageResId);
        textView.setText(text);
    }
}

@Override
public int getItemCount() {
    if (dataList.isEmpty()) {
        return 1; // 如果数据为空，则返回1，显示空视图
    }
    return dataList.size();
}

@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    if (viewType == VIEW_TYPE_EMPTY) {
        View emptyView = LayoutInflater.from(parent.getContext()).inflate(R.layout.empty_view, parent, false);
        return new EmptyViewHolder(emptyView);
    }

    // 创建其他类型的ViewHolder
    // ...

    return null;
}

@Override
public int getItemViewType(int position) {
    if (dataList.isEmpty()) {
        return VIEW_TYPE_EMPTY; // 返回空视图的View类型
    }

    // 返回其他类型的View类型
    // ...

    return super.getItemViewType(position);
}

@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
    if (holder instanceof EmptyViewHolder) {
        EmptyViewHolder emptyViewHolder = (EmptyViewHolder) holder;
        emptyViewHolder.bindData(R.drawable.empty_image, "列表为空");
    } else {
        // 绑定其他类型的数据
        // ...
    }
}
