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()}

    
    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Style
        myLocationStyle.isMyLocationShowing
        mBindingView.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

 
    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_FORECAST
    private 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()
    }
    
    override fun onWeatherLiveSearched(p0: LocalWeatherLiveResult?, p1: Int) {
        if (p1 == 1000) {
            if (p0 != null) {
                val weatherLive = p0.liveResult
                toast("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

    
    private fun mapping() {
        //绘制marker
        if (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)
        )
    }

好了基本上就这些 还有很多功能高德开放平台有很多接入实列 也很清楚 所以这里只是一点点皮毛 大家也可以去看看官方文档！也希望大家多多支持点赞，谢谢。
