如何在安卓系统中更改回收站onCreateViewHolder中特定LinearLayout的子项的颜色

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<DataItem> mDataList;

    public MyAdapter(List<DataItem> dataList) {
        mDataList = dataList;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_layout, parent, false);
        return new ViewHolder(itemView);
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        DataItem item = mDataList.get(position);
        holder.setColor(item.getColor());
    }

    @Override
    public int getItemCount() {
        return mDataList.size();
    }

    public static class ViewHolder extends RecyclerView.ViewHolder {
        private LinearLayout mLinearLayout;

        public ViewHolder(View itemView) {
            super(itemView);
            mLinearLayout = itemView.findViewById(R.id.linear_layout);
        }

        public void setColor(int color) {
            mLinearLayout.setBackgroundColor(color);
        }
    }
}
