BaseNodeAdapter树形列表上拉加载更多怎么刷新数据呢?根据官方的部分例子,我这样刷新不行

在loadMore回调函数我这样处理的:
@Override
public void onLoadMore() {
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
// mAdapter.nodeAddData(new FirstNode(),getEntity());
// mDatas.addAll(getEntity());
mAdapter.setList(getEntity());
mAdapter.getLoadMoreModule().loadMoreComplete();
}
},1000);
}

private List getEntity() {
//总的 list，里面放的是 FirstNode
List list = new ArrayList<>();

    for (int i = 0; i < 5; i++) {
        //SecondNode 的 list
        List<BaseNode> secondNodeList = new ArrayList<>();
        for (int n = 0; n <= 3; n++) {
            SecondNode seNode = new SecondNode("Second Node " + n);
            secondNodeList.add(seNode);
        }
        FirstNode entity = new FirstNode(secondNodeList, "First Node " + i);
        list.add(entity);
    }
    return list;
}

Start at the BaseNodeAdapter onLoadMore callback and compare the shown setList(getEntity()) call with the commented nodeAddData and mDatas.addAll approaches. Verify how the tree data is refreshed before loadMoreComplete() is called; done means newly loaded FirstNode and SecondNode entries appear in the list.
