需求分析
在现有地点中解析其地点优先级,最小到区县,当前区县可指定作业优先级,当绑定优先级数据后的数据应在选择时优先展示。
行政优先级维护
采用百度地图数据很行行政区域编码维护,考虑到现有数据是人工维护,获取其省市区县可能不准确,所以先根据其经纬度定位后可准确获取其省市区县,然后再进行编码维护。
示例
地点北京市东城区天安门，百度坐标116.403963,39.915119

当前区域指定优先级作业后数据优先展示
例如北京市有N个区,指定了N个规划路线,当东城区指定了由最近的骑手配送时，则点击东城区商家的配送线路优先展示

bug修复
当前查询出东城区绑定优先级为1.2.3.4时，查询出来的顺序更新索引位置会变为4.3.2.1，且考虑到list会多个且可重复重新更改代码

bug再次修复终极版
当存在多个优先级相同的区域路线时，会因为本身在list的位置不同，导致最后只有第一个正确，其他元素位置不正确
