:bool contentKey(String)      /判断key是否相同
:String getDisplayItem()       //返回显示字符串
:String setDeviceParam(int)    //输入list下标，设置真实key和value到设备中
另外，三个子类ParamNode分别用于确定枚举类型或范围类型或单值类型，包括：
枚举类型ParamNode，后缀为“-values”…；
范围类型ParamNode，后缀为“-min”，“-step”…，前缀为“max-”，“min-”…；
单值类型ParamNode，isNodeType永远返回true。
图3为实现相机参数读写方法的逻辑图，在系统中运行上述代码，则可以实现如图3所示的逻辑：
首先，通过代码mDevice＝Camera.open实现相机初始化，通过代码Parameters p＝Camera.getParameters()；
String str＝p.flatten()；
读取相机参数类，获得字符串。
进而，判断是否可以读取字符串中的一对参数，即键和键值，若是，则顺序遍历所有类型的子类ParamNode，isNodeType(key)为真时，确定nCurType类为当前类型，否则，遍历链表节点调用prepareValueList类。
其中，在确定nCurType为当前类型之后，遍历链表节点，判断是否有contentKey(key)为真的节点，若是，则插入该节点，进而在查询到的该节点为单值类型，则将节点转为nCurType的ParamNode，若否则调用nCurType类createNode(key)，链接节点到链表中。然后，通过代码setData(value)进行赋值，并返回执行判断是否可以读取字符串中的一对参数的步骤。
从而，执行图3所示的逻辑之后，顺序读取节点链接，添加到应用的界面菜单中，主菜单显示列表为遍历链表查到的所有节点显示字符串getDisplayItem，设置主菜单onItemClicked响应事件，显示二级菜单列表为选中主菜单列表项节点的getValues。设置二级菜单onItemClicked响应事件，调用节点的setDeviceParam。
