1、在项目中用到了这个控件【展示并选择某公司的部门】，但是在使用过程中又出一个问题——我并不知道该公司有几个部门，部门下面是否有子部门？
2、实现步骤如下：【开发工具：Android studio】
① 在项目中添加依赖：compile 'com.github.bmelnychuk:atv:1.2.+' 【是GitHub上的一个框架,搜索AndroidTreeView】
② 跟着GitHub上的介绍来做就可以了【如果是已知的部门结构的话，照着GitHub上写就能完成了，问题：不知道多少部门，不知道到部门层级】
③ 具体代码如下：【注意看注释，会有你想要的】

④ 代码执行过程：进入该Activity添加根节点，根节点添加parent节点【公司】，得到parent下面的子部门，判断子部门下还有子部门则继续请求，没有则不请求。
开始请求就弹出“加载中..”的progressdialog【cancelable=false】，返回则取消，直到最后一次返回才dialog消失。这个时候可以点节点点出子级部门
