Android 具有动态添加子行功能的自定义可扩展列表

我有我在这里发布的屏幕。在此屏幕中，有一个可展开的列表视图，其中包含子项，在0位置有“添加”按钮以添加新的子项。当我再次单击子项时，视图必须可见，并且我可以在“添加字段”按钮上为其添加子项。请告诉我怎么做，或者如果您曾经这样做过，请发布代码片段。

我认为这是一个多级可扩展的listview，您可以通过在运行时添加视图并使用do set标记和get标记来获得可见的子项，例如在可见中

private void generateList(final ArrayList<Beanclass> arrayList)
    {
        View view = null;
        ViewHolder viewHolder;

        try
        {
            llContainerremoveAllViews();

            if (arrayList != null && arrayList.size() > 0)
            {
                for (int i = 0; i < arrayList.size(); i++)
                {
                    view = LayoutInflater.from(MainActivity.this).inflate(R.layout.header_row, null, false);
                    viewHolder = new ViewHolder();

                    viewHolder.rlHeader = (RelativeLayout) view.findViewById(R.id.rlHeader);
                    viewHolder.imgUser = (ImageView) view.findViewById(R.id.imgUser);
                    viewHolder.txtName = (TextView) view.findViewById(R.id.txtName);
                    viewHolder.txtAddress = (TextView) view.findViewById(R.id.txtAddress);
                    viewHolder.llContainerChild = (LinearLayout) view.findViewById(R.id.llContainerChild);
                    view.setTag(viewHolder);

                    viewHolder.txtName.setText(arrayList.get(i).name);
                    viewHolder.txtAddress.setText(arrayList.get(i).business_address);

                    String imgUrl = arrayList.get(i).user_img_url;
                    if (imgUrl != null && !imgUrl.equalsIgnoreCase(""))
                    {
                        Picasso.with(MainAcitivity.this).load(imgUrl).into(viewHolder.imgUser);
                        viewHolder.imgUser.setScaleType(ScaleType.FIT_XY);
                    }

                    generateListChild(viewHolder.llContainerChild, arrayList.get(i).arrayListUser, arrayList.get(i).id);

                    arrayListViewHolderChilds.add(i, holderChild);
