一个Android无限级树菜单的实践代码,详细演示了一个树形菜单的制作过程,用到的关键点都附加了注释,学习制作树形菜单是完美的范例。可了解到如何设置父节点、获得父节点、设置节点文本、设置节点图标文件、清除所有子节点、删除指定位置的子节点、设置是否拥有复选框、是否为叶节点,即没有子节点的节点、递归判断所给的节点是否当前节点的父节点、递归判断父节点是否处于折叠状态,有一个父节点折叠则认为是折叠状态等。-An Android Unlimited practice-level tree menu code, detailed demonstration of the process of making a tree menu, use the key points are appended notes, learn how to make tree menu is the perfect example. Can learn how to set the parent node' s parent node, setting the node text, set the node icon file, remove all child nodes of the child node to delete the specified location, check whether you have set, is a leaf node, the node has no children nodes recursively determine whether the current node of the given node' s parent node, recursively determine whether the parent node is collapsed, there is a parent node is considered to be folded collapsed status.
