经纬度转换为地址信息

小编今天介绍两种方案：

一、高德地图

　　1、在build.gradle添加依赖：compile 'com.amap.api:search:latest.integration'

　　2、编写java代码

　　

  private fun setAddress(lat: Double?, lon: Double?) {

        if (lat == null || lon == null) {
            tv_adress.text = "暂无"
        } else {
            val latLng = LatLng(lat, lon)
            val gs = GeocodeSearch(this)
            //逆地理编码查询条件：逆地理编码查询的地理坐标点、查询范围、坐标类型。
            val latLonPoint = LatLonPoint(latLng.latitude, latLng.longitude)
            val query = RegeocodeQuery(latLonPoint, 500f, GeocodeSearch.AMAP)
            //异步查询
            gs.getFromLocationAsyn(query)
            gs.setOnGeocodeSearchListener(object : GeocodeSearch.OnGeocodeSearchListener {
                override fun onGeocodeSearched(p0: GeocodeResult?, p1: Int) {

                }

                override fun onRegeocodeSearched(regeocodeResult: RegeocodeResult?, p1: Int) {
                    if (p1 == 1000) {
                        val regeocodeAddress = regeocodeResult!!.regeocodeAddress
                        val formatAddress = regeocodeAddress.formatAddress
                        if (formatAddress != null) {
                            tv_adress.text = formatAddress
                        }
                    }


                }
            })
        }
    }

二、百度地图api

　　1、api的官方文档：http://lbsyun.baidu.com/index.php?title=webapi/guide/webservice-geocoding 

　　2、例如：http://api.map.baidu.com/geocoder/v2/?location=30.572998,104.067046&output=json&pois=0&ak=YBqIaSUHGsebc76AiGPGWkE0YGbELfAG
