首先切记利用到地图，万物归结于经纬度

效果图：

1.基于高德的经纬度（也是基于高德坐标系）

配置：导入AMap_Location_Vxxx.jar和AMap_Search_Vxxx.jar。这里编辑器文件，应该看得懂的
高德一些其他配置就不说了，按高德定位SDK配置就行

先根据地址获取高德地图的经纬度

private fun getLatlon(context:Context,cityName: String,selectItem:String) {
    val geocodeSearch = GeocodeSearch(context)
    geocodeSearch.setOnGeocodeSearchListener(object : GeocodeSearch.OnGeocodeSearchListener {

        override fun onRegeocodeSearched(p0: RegeocodeResult?, p1: Int) {

        }

        override fun onGeocodeSearched(geocodeResult: GeocodeResult?, i: Int) {
            if (i == 1000) {
                if (geocodeResult?.geocodeAddressList != null && geocodeResult.geocodeAddressList.size > 0) {
                    val geocodeAddress: GeocodeAddress = geocodeResult.geocodeAddressList.get(0)
                    val latitude: Double = geocodeAddress.latLonPoint.getLatitude() //纬度
                    val longititude: Double = geocodeAddress.latLonPoint.getLongitude() //经度
                    val adcode: String = geocodeAddress.getAdcode() //区域编码
                    Log.e("lgq地理编码", geocodeAddress.getAdcode().toString() + "")
                    Log.e("lgq纬度latitude", latitude.toString() + "")
                    Log.e("lgq经度longititude", longititude.toString() + "")
                    Log.i("lgq", "dddwww====$longititude")
                    when(selectItem){
                        "高德地图" -> {
                            MapUtil.openGaoDeNavi(context,0.0,0.0,null,latitude,longititude,cityName)
                            //MapUtil.openGaoDeNavi(mActivity,0.0,0.0,null,)
                        }
                        "百度地图" -> {
                            MapUtil.openBaiDuNavi(context,0.0,0.0,null,latitude,longititude,cityName)
                        }
                        "腾讯地图" -> {
                            MapUtil.openTencentMap(context,0.0,0.0,null,latitude,longititude,cityName)
                        }
                    }

                    //getCityAddress(longititude, latitude)
                } else {
                    ToastUtils.showCustomToast("地名出错")

                }
            }
        }

    })
    val geocodeQuery = GeocodeQuery(cityName.trim { it <= ' ' }, "29")
    geocodeSearch.getFromLocationNameAsyn(geocodeQuery)
}

2.完整关键的的MapUtil

public class MapUtil {

public static final String PN_GAODE_MAP = "com.autonavi.minimap";// 高德地图包名
public static final String PN_BAIDU_MAP = "com.baidu.BaiduMap"; // 百度地图包名
public static final String PN_TENCENT_MAP = "com.tencent.map"; // 腾讯地图包名

/**

    return isInstallPackage(PN_GAODE_MAP);
}

public static boolean isBaiduMapInstalled(){
    return isInstallPackage(PN_BAIDU_MAP);
}

public static boolean isTencentMapInstalled(){
    return isInstallPackage(PN_TENCENT_MAP);
}

private static boolean isInstallPackage(String packageName) {
    return new File("/data/data/" + packageName).exists();
}

    double x = bd_lon - 0.0065, y = bd_lat - 0.006;
    double z = Math.sqrt(x * x + y * y) - 0.00002 * Math.sin(y * PI);
    double theta = Math.atan2(y, x) - 0.000003 * Math.cos(x * PI);
