使用picasso将图像从数据库加载到recyclerview

implementation 'com.squareup.picasso:picasso:2.71828'

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<String> imageUrls; // 图像URL列表

    public MyAdapter(List<String> imageUrls) {
        this.imageUrls = imageUrls;
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull 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(@NonNull ViewHolder holder, int position) {
        String imageUrl = imageUrls.get(position);
        Picasso.get()
                .load(imageUrl)
                .placeholder(R.drawable.placeholder) // 加载中显示的占位图
                .error(R.drawable.error) // 加载失败显示的错误图
                .into(holder.imageView);
    }

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

    public static class ViewHolder extends RecyclerView.ViewHolder {
        ImageView imageView;

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

public class MainActivity extends AppCompatActivity {
    private RecyclerView recyclerView;
    private MyAdapter adapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        recyclerView = findViewById(R.id.recycler_view);
        recyclerView.setLayoutManager(new LinearLayoutManager(this));

        List<String> imageUrls = getImageUrlsFromDatabase(); // 从数据库获取图像URL列表
        adapter = new MyAdapter(imageUrls);
        recyclerView.setAdapter(adapter);
    }

    private List<String> getImageUrlsFromDatabase() {
        // 从数据库获取图像URL列表的逻辑
        // ...
