一、获取高德平台key
【1】基于application包名sha1值在高德控制台获取key值详情参考 获取Key-创建工程-开发指南-Android 地图SDK | 高德地图API
【2】在manifest中声明权限
【3】将拿到的key值在manifest中进行声明 !--允许程序打开网络套接字--
uses-permission android:nameandroid.permission.INTERNET /
!--允许程序设置内置sd卡的写权限--
uses-permission android:nameandroid.permission.WRITE_EXTERNAL_STORAGE /
!--允许程序获取网络状态--

!--允许程序访问CellID或WiFi热点来获取粗略的位置--
uses-permission android:nameandroid.permission.ACCESS_COARSE_LOCATION /
meta-dataandroid:namecom.amap.api.v2.apikeyandroid:valuexxxxxxxxxxxx /
二、集成依赖
在app build.gradle文件中增加高德地图依赖
implementation(com.amap.api:3dmap:9.8.2)
三、显示地图
概述-Android 地图SDK | 高德地图API
在xml文件中声明MapView控件并在class中重写 onCreate 方法此方法必须重写注意生命周期的管理
com.amap.api.maps.MapViewandroid:idid/mapandroid:layout_widthmatch_parentandroid:layout_heightmatch_parent /
private var mapView: MapView? nulloverride fun onCreate(savedInstanceState: Bundle?) {super.onCreate(savedInstanceState)setContentView(R.layout.test_activity)mapView findViewById(R.id.map)mapView?.onCreate(savedInstanceState)
}override fun onResume() {super.onResume()mapView?.onResume()
}override fun onPause() {super.onPause()mapView?.onPause()
}override fun onDestroy() {super.onDestroy()mapView?.onDestroy()
}override fun onSaveInstanceState(outState: Bundle) {super.onSaveInstanceState(outState)mapView?.onSaveInstanceState(outState)
} 地图默认中心点为北京天安门 四、高德地图具体使用 以下对于地图的控制使用之前需要拿到AMap对象 map mapView?.map
1、切换城市中心点
private fun moveCenterTo(latLng: LatLng) {val cameraUpdate CameraUpdateFactory.newLatLng(latLng)map?.moveCamera(cameraUpdate)
} Android高德地图切换城市中心点展示 2、设置缩放级别
moveCamera(CameraUpdateFactory.zoomTo(14.0f)) 3、绘制marker
companion object {private val MARKER1 LatLng(40.02855349893361, 116.3052948784071)private val MARKER2 LatLng(41.093445392798934, 116.11030767409169)
}val marker1: MarkerOptions MarkerOptions().apply {position(MARKER1)
}
val marker2: MarkerOptions MarkerOptions().apply {position(MARKER2)
}val list ArrayListMarkerOptions()
list.add(marker1)
list.add(marker2)
map?.addMarkers(list, false)
如下图所示不设置icon默认展示蓝色定位图标。

针对marker可以设置的属性
position在地图上标记位置的经纬度值必填参数title点标记的标题snippet点标记的内容draggable点标记是否可拖拽visible点标记是否可见anchor点标记的锚点alpha点的透明度 public final java.util.ArrayListMarker addMarkers(java.util.ArrayListMarkerOptions options, boolean moveToCenter) 在地图上添一组图片标记marker对象并设置是否改变地图状态以至于所有的marker对象都在当前地图可视区域范围内显示。 参数: options - 多个markerOptions对象它们分别定义了对应marker的属性信息。 moveToCenter - 是否改变地图状态默认为false。 返回: 返回一组被添加的marker对象。 4、绘制折线
val latLngList ArrayListLatLng()
latLngList.add(MARKER1)
latLngList.add(MARKER2)
map?.addPolyline(PolylineOptions().addAll(latLngList).width(3f).color(Color.RED)
) 5、轨迹
SmoothMoveMarker(map).apply {
setDescriptor(BitmapDescriptorFactory.fromResource(R.drawable.smooth))setPoints(latLngList)setTotalDuration(5)startSmoothMove()}
6、两点之间距离计算
AMapUtils.calculateLineDistance(latLng1,latLng2)
7、切换地图图层
【1】预设模式
mapType AMap.MAP_TYPE_NIGHT
【2】在线自定义模式
val options CustomMapStyleOptions().apply {isEnable truestyleId
}
map?.setCustomMapStyle(options)
8、手势交互
map?.uiSettings.let {it.isRotateGesturesEnabled falseit.isZoomControlsEnabled falseit.isTiltGesturesEnabled false
}
更多设置可参考https://a.amap.com/lbs/static/unzip/Android_Map_Doc/3D/index.html?overview-summary.html 9、地图状态监听 setOnMapLoadedListener(object : AMap.OnMapLoadedListener {override fun onMapLoaded() {Log.e(TAG, onMapLoaded...)}})//自带放大缩小接口setOnCameraChangeListener(object : AMap.OnCameraChangeListener {override fun onCameraChange(p0: CameraPosition?) {//Log.e(TAG, onCameraChange ${p0?.toString()})}override fun onCameraChangeFinish(p0: CameraPosition?) {Log.e(TAG, onCameraChangeFinish ${p0?.toString()})}})//map point点击事件addOnMapClickListener(object : AMap.OnMapClickListener {override fun onMapClick(p0: LatLng?) {Log.e(TAG, onMapClick ${p0?.toString()})}})//地图自带poi点击事件addOnPOIClickListener(object : AMap.OnPOIClickListener {override fun onPOIClick(p0: Poi?) {Log.e(TAG, onPOIClick ${p0?.toString()})}})addOnMarkerClickListener(object : AMap.OnMarkerClickListener {override fun onMarkerClick(p0: Marker?): Boolean {Log.e(TAG, onMarkerClick ${p0?.id})return true}}) 10、截图功能
拿到bitmap对象进行处理
map?.getMapScreenShot(object : AMap.OnMapScreenShotListener {override fun onMapScreenShot(p0: Bitmap?) {TODO(Not yet implemented)}override fun onMapScreenShot(p0: Bitmap?, p1: Int) {TODO(Not yet implemented)}})
