如何在RecyclerView中为多个进度条设置进度

// 适配器类
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<Item> itemList;

    public MyAdapter(List<Item> itemList) {
        this.itemList = itemList;
    }

    @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) {
        Item item = itemList.get(position);
        holder.progressBar.setProgress(item.getProgress());
    }

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

    // ViewHolder类
    public static class ViewHolder extends RecyclerView.ViewHolder {
        public ProgressBar progressBar;

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

// 数据源类
public class Item {
    private int progress;

    public Item(int progress) {
        this.progress = progress;
    }

    public int getProgress() {
        return progress;
    }

    public void setProgress(int progress) {
        this.progress = progress;
    }
}

// 在Activity或Fragment中使用RecyclerView
public class MainActivity extends AppCompatActivity {
    private RecyclerView recyclerView;
    private MyAdapter adapter;
    private List<Item> itemList;

    @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));

        itemList = new ArrayList<>();
        itemList.add(new Item(50));
        itemList.add(new Item(75));
        itemList.add(new Item(30));

        adapter = new MyAdapter(itemList);
        recyclerView.setAdapter(adapter);
    }
}
