如何使用volley在可扩展ListView中映射childView

dependencies {
    implementation 'com.android.volley:volley:1.2.0'
}

public class MyExpandableListAdapter extends BaseExpandableListAdapter {
    // 其他必要的方法

    @Override
    public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {
        // 创建或复用一个childView
        if (convertView == null) {
            LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = inflater.inflate(R.layout.child_view_layout, null);
        }

        // 获取当前child的数据
        ChildData childData = getChild(groupPosition, childPosition);

        // 在childView中设置数据
        TextView childTextView = convertView.findViewById(R.id.childTextView);
        childTextView.setText(childData.getText());

        // 返回childView
        return convertView;
    }
}

ExpandableListView expandableListView = findViewById(R.id.expandableListView);
MyExpandableListAdapter adapter = new MyExpandableListAdapter();
expandableListView.setAdapter(adapter);

// 创建一个请求队列
RequestQueue requestQueue = Volley.newRequestQueue(context);

// 创建一个GET请求
String url = "http://example.com/data";
StringRequest request = new StringRequest(Request.Method.GET, url,
        new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {
                // 解析服务器响应的数据
                List<GroupData> groupDataList = parseResponse(response);

                // 更新Adapter的数据源
                adapter.setGroupDataList(groupDataList);

                // 通知Adapter数据已更新
                adapter.notifyDataSetChanged();
            }
        },
        new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                // 处理请求错误
            }
        });

// 将请求添加到队列中
requestQueue.add(request);
