将相同的可点击的孩子添加到每个组的顶部可展开列表视图- android

// 创建数据源
List<String> groupList = new ArrayList<>();
groupList.add("Group 1");
groupList.add("Group 2");

List<List<String>> childList = new ArrayList<>();
List<String> child1 = new ArrayList<>();
child1.add("Child 1");
child1.add("Child 2");
childList.add(child1);

List<String> child2 = new ArrayList<>();
child2.add("Child 3");
child2.add("Child 4");
childList.add(child2);

// 创建适配器
ExpandableListAdapter adapter = new ExpandableListAdapter() {
    @Override
    public int getGroupCount() {
        return groupList.size();
    }

    @Override
    public int getChildrenCount(int groupPosition) {
        return childList.get(groupPosition).size();
    }

    @Override
    public Object getGroup(int groupPosition) {
        return groupList.get(groupPosition);
    }

    @Override
    public Object getChild(int groupPosition, int childPosition) {
        return childList.get(groupPosition).get(childPosition);
    }

    // 其他方法的实现...

    @Override
    public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {
        // 处理子项的布局和点击事件
        if (convertView == null) {
            // 创建子项布局
            convertView = LayoutInflater.from(parent.getContext()).inflate(R.layout.child_item_layout, parent, false);
        }

        // 设置子项内容
        TextView childTextView = convertView.findViewById(R.id.childTextView);
        childTextView.setText(childList.get(groupPosition).get(childPosition));

        // 添加相同的可点击的孩子到每个组的顶部
        if (childPosition == 0) {
            TextView sameChildTextView = new TextView(parent.getContext());
            sameChildTextView.setText("Same Child");
            parent.addView(sameChildTextView, 0);
        }

        return convertView;
    }
};

// 设置可展开列表视图
ExpandableListView expandableListView = findViewById(R.id.expandableListView);
expandableListView.setAdapter(adapter);
