如何在从数据库接收数据时设置Listview

// 数据模型类
public class Item {
    private String name;
    private String description;
    
    // 构造函数、getter和setter方法
    
    // ...
}

// 自定义适配器
public class CustomAdapter extends ArrayAdapter<Item> {
    private Context context;
    private List<Item> itemList;
    
    public CustomAdapter(Context context, List<Item> itemList) {
        super(context, 0, itemList);
        this.context = context;
        this.itemList = itemList;
    }
    
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView == null) {
            convertView = LayoutInflater.from(context).inflate(R.layout.list_item_layout, parent, false);
        }
        
        // 获取当前位置的数据项
        Item currentItem = itemList.get(position);
        
        // 在布局中找到对应的控件，将数据填充进去
        TextView nameTextView = convertView.findViewById(R.id.nameTextView);
        TextView descriptionTextView = convertView.findViewById(R.id.descriptionTextView);
        
        nameTextView.setText(currentItem.getName());
        descriptionTextView.setText(currentItem.getDescription());
        
        return convertView;
    }
}

// 在Activity中使用适配器设置ListView
public class MainActivity extends AppCompatActivity {
    private ListView listView;
    private CustomAdapter adapter;
    private List<Item> itemList;
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        listView = findViewById(R.id.listView);
        itemList = new ArrayList<>();
        
        // 从数据库中获取数据，将数据存储到itemList中
        
        // ...
        
        adapter = new CustomAdapter(this, itemList);
        listView.setAdapter(adapter);
    }
}
