目前已经实现3级之内的任意级树形结构展示（如果想增加更多级，需要扩展排序算法），并支持单选和多选（使用不同的适配器）。
实现使用的控件：ListView
首先，最重要的应该是数据源的格式，支持树形结构的数据源，每条数据应该都要指明它的父级是谁，本文为parent_org，并把每条数据都存放在一个HashMap里面。这里使用的除了parent_org（父营业部），还有org_name（营业部名称），org_code（营业部编号）。
其次，对数据进行排序。因为只使用ListView实现，所以需要实现层次结构的树形结构，需要对数据按父级->2级->3级->父级->2级->父级->2级->父级->2级->3级这样的顺序排序。
接着，实现适配器，展现树形结构。
最后，调用适配器，并调用适配器里的方法获取选择结果。
排序算法：
