首先切記利用到地圖，萬(wàn)物歸結(jié)于經(jīng)緯度

效果圖：

效果圖.png

1.基于高德的經(jīng)緯度（也是基于高德坐標(biāo)系）

配置：導(dǎo)入AMap_Location_Vxxx.jar和AMap_Search_Vxxx.jar。這里編輯器文件，應(yīng)該看得懂的
高德一些其他配置就不說(shuō)了，按高德定位SDK配置就行

先根據(jù)地址獲取高德地圖的經(jīng)緯度

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() //緯度
                    val longititude: Double = geocodeAddress.latLonPoint.getLongitude() //經(jīng)度
                    val adcode: String = geocodeAddress.getAdcode() //區(qū)域編碼
                    Log.e("lgq地理編碼", geocodeAddress.getAdcode().toString() + "")
                    Log.e("lgq緯度latitude", latitude.toString() + "")
                    Log.e("lgq經(jīng)度longititude", longititude.toString() + "")
                    Log.i("lgq", "dddwww====$longititude")
                    when(selectItem){
                        "高德地圖" -> {
                            MapUtil.openGaoDeNavi(context,0.0,0.0,null,latitude,longititude,cityName)
                            //MapUtil.openGaoDeNavi(mActivity,0.0,0.0,null,)
                        }
                        "百度地圖" -> {
                            MapUtil.openBaiDuNavi(context,0.0,0.0,null,latitude,longititude,cityName)
                        }
                        "騰訊地圖" -> {
                            MapUtil.openTencentMap(context,0.0,0.0,null,latitude,longititude,cityName)
                        }
                    }

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

                }
            }
        }

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

2.完整關(guān)鍵的的MapUtil
