本文详细介绍如何使用VirtualLayoutManager和DelegateAdapter进行复杂UI布局管理，包括初始化布局管理器、添加数据及设置适配器的过程。通过示例代码，展示了如何添加标题栏和功能按钮，实现动态调整的列表布局。

1.初始化布局管理器

VirtualLayoutManager layoutManager = new VirtualLayoutManager(this);
recyclerView.setLayoutManager(layoutManager);

2.添加数据，设置适配器

DelegateAdapter delegateAdapter = new DelegateAdapter(layoutManager, false);
List<DelegateAdapter.Adapter> adapters = new LinkedList<>();
for (int i = 0; i < mlist.size(); i++) {
    //添加标题栏
    addTitle(adapters,mlist.get(i).getCardBankName());
    //添加功能按钮
    addButton(adapters,mlist.get(i).getCardListItemInfo());
}
delegateAdapter.setAdapters(adapters);
recyclerView.setAdapter(delegateAdapter);

/**
 * 添加标题栏
 *
 * @param adapters
 * @param title
 */
private void addTitle(List<DelegateAdapter.Adapter> adapters, String title) {
    LinearLayoutHelper layoutHelper = new LinearLayoutHelper();
    layoutHelper.setPadding(10, 10, 10, 10);
    adapters.add(new AllFuncTitleAdapter(this, layoutHelper, 1, title));
}

/**
     * 添加功能按钮
     *
     * @param adapters
     * @param cardListItemInfo
     */
    private void addButton(List<DelegateAdapter.Adapter> adapters,List<CardListItemInfo> cardListItemInfo) {
//        GridLayoutHelper layoutHelper = new GridLayoutHelper(4);
        LinearLayoutHelper layoutHelper = new LinearLayoutHelper();
        layoutHelper.setBgColor(Color.WHITE);
//        layoutHelper.setAutoExpand(false);
        layoutHelper.setPadding(10, 10, 10, 10);
        adapters.add(new AllFuncButtonAdapter(this, layoutHelper, cardListItemInfo));
    }

private Context mContext;
private LayoutHelper layoutHelper;
private VirtualLayoutManager.LayoutParams mLayoutParams;
private List<CardListItemInfo> mList;

new VirtualLayoutManager.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,100)
