如何将自定义可绘制添加到数组中，然后添加到RecyclerView？

// 创建自定义可绘制对象
Drawable drawable1 = getResources().getDrawable(R.drawable.drawable1);
Drawable drawable2 = getResources().getDrawable(R.drawable.drawable2);
Drawable drawable3 = getResources().getDrawable(R.drawable.drawable3);

// 创建数组并添加可绘制对象
ArrayList<Drawable> drawableList = new ArrayList<>();
drawableList.add(drawable1);
drawableList.add(drawable2);
drawableList.add(drawable3);

// 创建RecyclerView适配器
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private ArrayList<Drawable> drawableList;

    public MyAdapter(ArrayList<Drawable> drawableList) {
        this.drawableList = drawableList;
    }

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

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        Drawable drawable = drawableList.get(position);
        holder.imageView.setImageDrawable(drawable);
    }

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

    public class ViewHolder extends RecyclerView.ViewHolder {
        ImageView imageView;

        public ViewHolder(View itemView) {
            super(itemView);
            imageView = itemView.findViewById(R.id.image_view);
        }
    }
}

// 设置RecyclerView的适配器
RecyclerView recyclerView = findViewById(R.id.recycler_view);
MyAdapter adapter = new MyAdapter(drawableList);
recyclerView.setAdapter(adapter);
