Question

我有一个小模块来列出android中的文件夹结构。如果用户单击一个节点（此节点是图标集合，即文件夹图标，箭头图标等），则会列出所选文件夹中的子文件夹。现在我想在一开始就显示根文件夹的子文件夹。现有的只显示根文件夹。如果我可以在一开始就调用节点项的单击侦听器，我可以轻松地完成此操作。我怎么能这样做。

public static void callFolderSection(Context context,int mailBox,Fragment fragment)
{
    AndroidTreeView tView;
    //selectedMailBox = mailBox;
    final Dialog dialog = new Dialog(context);
    dashContext = context;
    fragmentName = fragment;
    selectedMailBox = mailBox;

    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
    dialog.setContentView(R.layout.layout_default);
    ((DashboardActivity) context).dialogFolder = dialog;
    ViewGroup containerView = (ViewGroup) dialog.findViewById(R.id.container);

    MailServices mailServices = new MailServices();
    ArrayList<FolderSection> folderSectionList ;
    folderSectionList = mailServices.listFoldersAndSections("0",mailBox);

//获取根文件夹

    TreeNode root = TreeNode.root();
    TreeNode computerRoot = new TreeNode(new IconTreeItemHolder.IconTreeItem(GlobalVariables.getGsLoginProjectNo(),"0","0",fragment,0,0,folderSectionList.get(0).get_childCount()));
    for (int count = 0;count < folderSectionList.size();count++)
    {
        TreeNode treeNode = new TreeNode(new IconTreeItemHolder.IconTreeItem(folderSectionList.get(count).get_title(),Integer.toString(folderSectionList.get(count).get_int_Key()),Integer.toString(folderSectionList.get(count).get_int_parent()),fragmentName,folderSectionList.get(count).get_isSmartSection(),folderSectionList.get(count).get_itemCount(),folderSectionList.get(count).get_childCount()));
        computerRoot.addChildren(treeNode);
    }

    root.addChildren(computerRoot);

    tView = new AndroidTreeView(context, root);
    tView.setDefaultAnimation(true);
    tView.setDefaultContainerStyle(R.style.TreeNodeStyleCustom);
    tView.setDefaultViewHolder(IconTreeItemHolder.class);

//设置点击监听器

    tView.setDefaultNodeClickListener(nodeClickListener);

    containerView.addView(tView.getView());

    Window window = dialog.getWindow();
    if (GlobalVariables.getGsDevice().equals("tab")) {


    dialog.show();

}

//点击监听器

 private  static TreeNode.TreeNodeClickListener nodeClickListener = new TreeNode.TreeNodeClickListener() {
    @Override
    public void onClick(TreeNode node, Object value) {
        IconTreeItemHolder.IconTreeItem item = (IconTreeItemHolder.IconTreeItem) value;
        ((DashboardActivity) dashContext).folderIntKey = Integer.parseInt(item.int_Key);

        MailServices mailServices = new MailServices();
        DocumentServices documentServices = new DocumentServices();

        try {


            if (Integer.parseInt(item.int_Key) != 0) {
                if (node.getChildren().size() == 0) {

                    ArrayList<FolderSection> folderSectionList;
                    if(((DashboardActivity) dashContext).isFolderDoc)
                    {
                        folderSectionList = documentServices.listFoldersAndSections(item.int_Key);

                    }
                    else
                    {
                         folderSectionList = mailServices.listFoldersAndSections(item.int_Key, selectedMailBox);

                    }

                    for (int count = 0; count < folderSectionList.size(); count++) {
                        TreeNode treeNode = new TreeNode(new IconTreeItemHolder.IconTreeItem(folderSectionList.get(count).get_title(), Integer.toString(folderSectionList.get(count).get_int_Key()), Integer.toString(folderSectionList.get(count).get_int_parent()), fragmentName,folderSectionList.get(count).get_isSmartSection(),folderSectionList.get(count).get_itemCount(),folderSectionList.get(count).get_childCount()));
                        node.addChildren(treeNode);
                    }
                }
            }
        }
        catch (Exception ex)
        {

        }

    }
};

编辑：编辑代码snipets以适当的方式工作。

Answer 1

试试这个

nodeClickListener.onClick(node,value);

Node =您想要的节点。
值=它具有的值。

编辑：我读了库的代码，也许你可以使用

expandNode(TreeNode node)

Answer 2

使用 performClick（）方法。

因为你有根视图。

执行单击事件而不单击android listview
