Andriod实战项目开发之十四----树形结构，增加节点后如何处理页面的刷新机制

效果图

 public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        initData();
        LinearLayoutManager manager = new LinearLayoutManager(mActivity);
        mTreeListRecy = view.findViewById(R.id.mTreeListRecy);
        if (mTreeListRecy != null) {
            mTreeListRecy.setLayoutManager(manager);
            mTreeListRecy.setAdapter(adapter);
            //Tree2HeaderView tree2HeaderView = new Tree2HeaderView(mActivity);
            treeHeaderView = new TreeHeaderView(mActivity,dataList);
            adapter.addHeaderView(treeHeaderView);
            //ArrayList<String> list = new ArrayList<>();
            //for (int i = 0; i < 30; i++) {
                //list.add("数据" + i);
            //}
            //adapter.addData(list);
            initNode();

        } else {
            Log.e("GoodItemTreeFragment", "mTreeListRecy is null");
        }
    }

二、关键代码 initNode函数

public void initNode(){
        treeHeaderView.getAdapter().setTreeCheckedChangeListener(new TreeRecyclerViewAdapter.OnTreeCheckedChangeListener() {
            @Override
            public void onAddItem(N
