归纳下最近做的仿微信地理位置选择，T^T。避免下次再遇上类似功能需求又得重新去看高德开发文档。（此次这下本文也是基于本人刚删完代码就遇上需求，又重新看了一遍开发文档）。
先上效果图:

本文使用的是高德地图，jar包如下图，若高德以后更新版本可能会有些方法改变，所以本文只只对当前版本。

接下来归纳下本文所使用功能。
1.地图（这是必须的）
2.定位
3.添加标注(mark)
4.poi索引（地图下面的列表，PoiSearch）
5.逆地理编码(坐标转地址，用于移动地图后poi检索出周边，GeocodeSearch)
ok大概就这些了。
接下来上布局预览:

，这里的重新定位是自己定义的一个按钮，并不是用地图自带的(自带的在地图的右上角)，自定义的原因是自己之前封装好了一个定位，这里只要重新调用就行，纯属为了自己方便
地图跟定位是相对简单的，这里就不介绍了，
定位后把地图移动到当前地理位置，

重点看POI 和地理的逆编码

下面上一张poiItems的返回参数图，供参考

地理的逆编码：

只需传入经纬度，范围，第三个参数表示是火系坐标系还是GPS原生坐标系（具体的参考开发文档）
OK ，至此地图+地理列表页完成，剩下的就是手动输入地址检索出附近地址列表了（poi）因为这里已有类似代码，就不再介绍。
