将项目添加到在其他活动中使用baseAdapter的listView

public class ProjectAdapter extends BaseAdapter {
    private ArrayList<Project> projectList;
    // 其他成员变量和方法
    
    @Override
    public int getCount() {
        return projectList.size();
    }
    
    @Override
    public Object getItem(int position) {
        return projectList.get(position);
    }
    
    @Override
    public long getItemId(int position) {
        return position;
    }
    
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // 复用convertView以提高性能
        if (convertView == null) {
            convertView = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_project, parent, false);
        }
        
        // 设置item布局和数据
        Project project = projectList.get(position);
        TextView nameTextView = convertView.findViewById(R.id.nameTextView);
        TextView descriptionTextView = convertView.findViewById(R.id.descriptionTextView);
        nameTextView.setText(project.getName());
        descriptionTextView.setText(project.getDescription());
        
        return convertView;
    }
}

// 在活动中的使用示例
ListView listView = findViewById(R.id.listView);
ProjectAdapter adapter = new ProjectAdapter();
listView.setAdapter(adapter);

// 添加项目到数据结构中
projectList.add(new Project("项目名称", "项目描述"));

// 通知适配器数据发生变化
adapter.notifyDataSetChanged();
