我使用Liferay 6.2并使用Media Gallery Portlet显示放置在多个文件夹中的图像。我有多个文件夹，其中包含多个图像，但文件夹按字母顺序排列，但我的要求是安排最近更新的文件夹（即，最近更新的文件夹必须位于顶部）所以任何人都可以提供解决方案如何实现这一目标。

先谢谢。

Answer 1

通过hook或ext覆盖view.jsp /html/portlet/image_gallery_display并在{＃1}}对象的初始化下面的第11行添加以下两行：

SearchContainer

这将按照修改日期对您的媒体库的文件夹和图片进行排序。

<强>更新如果要从首选项控制此行为，则：

在OrderByComparator orderByComparator = DLUtil.getRepositoryModelOrderByComparator("modifiedDate", "desc"); searchContainer.setOrderByComparator(orderByComparator);：
中声明并初始化这些属性

init.jsp

在中添加以下用于值选择的下钻   String sortByCol = portletPreferences.getValue("sortByCol", "title"); String sortByOrder = portletPreferences.getValue("sortByOrder", "desc");：

configuration.jsp

在<div class="aui-column left-selector-column"> <aui:select label="Sort By" name="preferences--sortByCol--"> <aui:option label="Title" value="title" selected="<%= sortByCol.equals("title") %>" /> <aui:option label="Create Date" value="creationDate" selected="<%= sortByCol.equals("creationDate") %>"/> <aui:option label="Modified Date" value="modifiedDate" selected="<%= sortByCol.equals("modifiedDate") %>" /> </aui:select> </div> <div class="aui-column right-selector-column"> <aui:select label="Order" name="preferences--sortByOrder--"> <aui:option label="Ascending" value="asc" selected="<%= sortByOrder.equals("asc") %>"/> <aui:option label="Descending" value="desc" selected="<%= sortByOrder.equals("desc") %>"/> </aui:select> </div>下面添加这两行   SearchContainer初始化：

view.jsp
