向多级可扩展LisView的每个ChildItem添加Toast

// 创建多级可扩展ListView
ExpandableListView expandableListView = findViewById(R.id.expandableListView);

// 创建适配器
ExpandableListAdapter adapter = new ExpandableListAdapter() {
    // 实现适配器的其他方法...

    @Override
    public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {
        // 获取ChildItem的视图
        View childView = LayoutInflater.from(context).inflate(R.layout.child_item_layout, parent, false);

        // 为ChildItem的视图添加点击事件监听器
        childView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // 显示Toast消息
                Toast.makeText(context, "点击了ChildItem " + childPosition, Toast.LENGTH_SHORT).show();
            }
        });

        // 返回ChildItem的视图
        return childView;
    }
};

// 设置适配器
expandableListView.setAdapter(adapter);
