kotlin版高德地图集成实现夜景切换，卫星图，英文切换，当前天气，地图位置标记等基础实现.

上图为实现后效果默认+地图标点> 英文>夜景地图>卫星地图>获取当前天气

接下来我们集成地图

1.我们去高德地图开放平台注册（高德开放平台 | 高德地图API）申请key(可以用QQ ，邮箱等注册登录)

在这里创建应用会让你输入名字和应用类型（自己看需求填写测试的话没什么特殊要求）完成后如图：

我们点击添加添加

获取sha1

这样我就吧对应的sha1复制到高德key申请页面确定后会生成对应的key 如图

2.在代码中添加高德地图配置

具体配置看高德开发文档吧：Android Studio 配置工程-创建工程-开发指南-Android 地图SDK | 高德地图API：

3.代码实现主要功能

3.1地图基础设置

private val mLocationClient:AMapLocationClient by lazy { AMapLocationClient(this) }
private val mLocationOption:AMapLocationClientOption by lazy {AMapLocationClientOption()}/*** 地图基础设置*/private fun mapBasicSettings() {//设置定位回调监听mLocationClient.setLocationListener(this)//设置为高精度定位模式mLocationOption.locationMode = AMapLocationMode.Hight_Accuracy//设置定位参数mLocationClient.setLocationOption(mLocationOption)// 此方法为每隔固定时间会发起一次定位请求，为了减少电量消耗或网络流量消耗，// 注意设置合适的定位时间的间隔（最小间隔支持为2000ms），并且在合适时间调用stopLocation()方法来取消定位请求// 在定位结束后，在合适的生命周期调用onDestroy()方法// 在单次定位情况下，定位无论成功与否，都无需调用stopLocation()方法移除请求，定位sdk内部会移除mLocationClient.startLocation() //启动定位val myLocationStyle = MyLocationStyle()//连续定位、且将视角移动到地图中心点，定位点依照设备方向旋转，并且会跟随设备移动。（1秒1次定位）如果不设置myLocationType，默认也会执行此种模式。myLocationStyle.myLocationType(MyLocationStyle.LOCATION_TYPE_MAP_ROTATE_NO_CENTER)//设置连续定位模式下的定位间隔，只在连续定位模式下生效，单次定位模式下不会生效。单位为毫秒。myLocationStyle.interval(2000)//设置定位蓝点的StylemyLocationStyle.isMyLocationShowingmBindingView.mapView.map.myLocationStyle = myLocationStyle// 显示实时交通状况mBindingView.mapView.map.isTrafficEnabled = true//true：显示室内地图；false：不显示；mBindingView.mapView.map.showIndoorMap(true)//设置默认定位按钮是否显示，非必需设置。mBindingView.mapView.map.uiSettings.isMyLocationButtonEnabled = true// 设置为true表示启动显示定位蓝点，false表示隐藏定位蓝点并不进行定位，默认是false。mBindingView.mapView.map.isMyLocationEnabled = true}

3.2 实现上图中左侧点击后功能

 /*** 点击事件*/private fun setListener() {//导航地图mBindingView.tvNavigation.setOnClickListener {mBindingView.mapView.map.mapType = AMap.MAP_TYPE_NAVI}//夜景地图mBindingView.tvNightView.setOnClickListener {mBindingView.mapView.map.mapType = AMap.MAP_TYPE_NIGHT}//白昼地图（即普通地图）mBindingView.tvDay.setOnClickListener {mBindingView.mapView.map.mapType = AMap.MAP_TYPE_NORMAL}//卫星图mBindingView.tvSatellite.setOnClickListener {mBindingView.mapView.map.mapType = AMap.MAP_TYPE_SATELLITE}//获取当前定位城市天气mBindingView.tvWeather.setOnClickListener {lifecycleScope.launch {searchWeather(mLocation?.city.toString())}}//切换中英文mBindingView.tvLanguage.text = getString(R.string.switch_english)mBindingView.tvLanguage.setOnClickListener {if (mBindingView.tvLanguage.text.toString() == getString(R.string.switch_english)) {mBindingView.mapView.map.setMapLanguage("en")mBindingView.tvLanguage.text = getString(R.string.switch_chinese)} else {mBindingView.mapView.map.setMapLanguage("zh_cn")mBindingView.tvLanguage.text = getString(R.string.switch_english)}}}//检索参数为城市和天气类型，实况天气为WEATHER_TYPE_LIVE、天气预报为WEATHER_TYPE_FORECASTprivate fun searchWeather(text: String) {val mQuery = WeatherSearchQuery(text, WeatherSearchQuery.WEATHER_TYPE_LIVE)val mWeatherSearch = WeatherSearch(this)mWeatherSearch.setOnWeatherSearchListener(this)mWeatherSearch.query = mQuery//异步搜索mWeatherSearch.searchWeatherAsyn()}/*** 获取天气查询结果*/override fun onWeatherLiveSearched(p0: LocalWeatherLiveResult?, p1: Int) {if (p1 == 1000) {if (p0 != null) {val weatherLive = p0.liveResulttoast("今天天气： " + weatherLive.weather + "\n今天温度:  " + weatherLive.getTemperature() + "°")} else {toast("获取天气数据出错：$p0")}}}override fun onWeatherForecastSearched(p0: LocalWeatherForecastResult?, p1: Int) {}

3.3实现地图标点

    /*** 地图绘制* markerLocation数据是经纬度的一个list集合*/private fun mapping() {//绘制markerif (markerLocation.size > 0) {mBindingView.mapView.map.moveCamera(CameraUpdateFactory.changeLatLng(LatLng(markerLocation[0].Laitude!!,markerLocation[0].Longitude!!)))for (map in 0 until markerLocation.size) {mBindingView.mapView.map.addMarker(MarkerOptions().position(LatLng(markerLocation[map].Laitude!!,markerLocation[map].Longitude!!)).title(markerLocation[map].HotelName).snippet(markerLocation[map].HotelAddress + "\n" + "维度:" + markerLocation[map].Laitude + "/" + "经度：" + markerLocation[map].Longitude).icon(BitmapDescriptorFactory.fromBitmap(BitmapFactory.decodeResource(resources,R.mipmap.icon_site))).draggable(true))}}// 绘制曲线mBindingView.mapView.map.addPolyline(PolylineOptions().add(LatLng(43.828, 87.621), LatLng(45.808, 126.55)).geodesic(true).color(Color.RED))}

部分功能其实很简单主要代码也就贴在上面了下面我把全部代码贴出来
