                                    在使用到百度地图经纬度和地址相互转换的时候，我们最最最首先需要的是集成百度地图，让我们的APP能够拥有百度的jar包功能，然后在我们所需要转换的activity或者fragment中implements OnGetGeoCoderResultListener，这样我们就可以进行下一步的操作开发了(╹▽╹)private GeoCoder mSearch = null; // 搜索模块，也可去掉地图...
                                    1.地理编码查询接口是单列模式的,我们需要调用让它自己实例化// 在OnCreate方法里创建地理编码检索实例GeoCoder geoCoder = GeoCoder.newInstance();2.调用这个方法把你想要的经纬度传入/** * 经纬度或地址相互转换** @param latlng*/private void latlngToAddress(LatLng latlng) {// 设置...

一、定位介绍
在不使用第三方地图SDK的情况下，也可以借助Android
本身的定位API来实现相关地理位置功能更，官方介绍见这里（需要翻墙）：https://developer.android.com/reference/android/locatio...
android:name="android.permission.ACCESS_COARSE_LOCATION"
android:name="android.permission.ACCESS_FINE_LOCATION"
1.1其次最重要的是，申请权限，一直真机调试不成功，折磨死我啦，放在protected void o
       实现经纬度转为地址信息，主要用到的类是GeoCoder，通过newInstance获得类的实例。
       用到的方法为 public boolean reverseGeoCode(ReverseGeoCodeOption option)即反向解析，发起反地理编码请求(经纬度->地址信息)
       与其对应的是方法为 public boolean
