我要创建横向菜单的机器人。 Android支持扩展列表视图纵向伸长，但我想水平扩展菜单。请参考图片

I want to create horizontal menu in android. Android supports expandable list view that expands vertically but i want to expand menus horizontally. Please refer image

说明：

在图像菜单1，MENU2，菜单3是主菜单和S1，S2，S3是菜单1的子项如果我点击主菜单上的它的子项必须扩大。

In the images Menu1,menu2,menu3 are main menus and s1,s2,s3 are sub items of menu 1. If i clicked on main menu its sub items must be expand.

您可以将子菜单中的LinearLayout，并添加玩View.VISIBLE / View.GONE在onClickListener
