Android 使用高德地图

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

  1. <!--允许程序打开网络套接字-->
  2. <uses-permission android:name="android.permission.INTERNET" />
  3. <!--允许程序设置内置sd卡的写权限-->
  4. <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />   
  5. <!--允许程序获取网络状态-->
  6. <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 
  7. <!--允许程序访问WiFi网络信息-->
  8. <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> 
  9. <!--允许程序访问CellID或WiFi热点来获取粗略的位置-->
  10. <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> 
  1. <meta-data
  2.             android:name="com.amap.api.v2.apikey"
  3.             android:value="xxxxxxxxxxxx" />

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

  1. <com.amap.api.maps.MapView
  2.         android:id="@+id/map"
  3.         android:layout_width="match_parent"
  4.         android:layout_height="match_parent" />
  1. private var mapView: MapView? = null
  2.  
  3. override fun onCreate(savedInstanceState: Bundle?) {
  4.     super.onCreate(savedInstanceState)
  5.     setContentView(R.layout.test_activity)
  6.     mapView = findViewById(R.id.map)
  7.     mapView?.onCreate(savedInstanceState)
  8. }
  9.  
  10. override fun onResume() {
  11.     super.onResume()
  12.     mapView?.onResume()
  13. }
  14.  
  15. override fun onPause() {
  16.     super.onPause()
  17.     mapView?.onPause()
  18. }
  19.  
  20. override fun onDestroy() {
  21.     super.onDestroy()
  22.     mapView?.onDestroy()
  23. }
  24.  
  25. override fun onSaveInstanceState(outState: Bundle) {
  26.     super.onSaveInstanceState(outState)
  27.     mapView?.onSaveInstanceState(outState)
  28. }

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

  1. private fun moveCenterTo(latLng: LatLng) {
  2.     val cameraUpdate = CameraUpdateFactory.newLatLng(latLng)
  3.     map?.moveCamera(cameraUpdate)
  4. }

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

  1. companion object {
  2.     private val MARKER1 = LatLng(40.02855349893361, 116.3052948784071)
  3.     private val MARKER2 = LatLng(41.093445392798934, 116.11030767409169)
  4. }
  5.  
  6.  
  7. val marker1: MarkerOptions = MarkerOptions().apply {
  8.     position(MARKER1)
  9. }
  10. val marker2: MarkerOptions = MarkerOptions().apply {
  11.     position(MARKER2)
  12. }
  13.  
  14. val list = ArrayList<MarkerOptions>()
  15. list.add(marker1)
  16. list.add(marker2)
  17. map?.addMarkers(list, false)

如下图所示，不设置icon默认展示蓝色定位图标。

11

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.ArrayList<Marker> addMarkers(java.util.ArrayList<MarkerOptions> 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

  1. val latLngList = ArrayList<LatLng>()
  2. latLngList.add(MARKER1)
  3. latLngList.add(MARKER2)
  4. map?.addPolyline(
  5.     PolylineOptions().addAll(latLngList).width(3f).color(Color.RED)
  6. )

5、轨迹

  1. SmoothMoveMarker(map).apply {
  2. setDescriptor(BitmapDescriptorFactory.fromResource(R.drawable.smooth))
  3.                 setPoints(latLngList)
  4.                 setTotalDuration(5)
  5.                 startSmoothMove()
  6.             }

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

  1. val options = CustomMapStyleOptions().apply {
  2.     isEnable = true
  3.     styleId = ""
  4. }
  5. map?.setCustomMapStyle(options)

8、手势交互

  1. map?.uiSettings.let {
  2.     it.isRotateGesturesEnabled = false
  3.     it.isZoomControlsEnabled = false
  4.     it.isTiltGesturesEnabled = false
  5. }

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

  1.             setOnMapLoadedListener(object : AMap.OnMapLoadedListener {
  2.                 override fun onMapLoaded() {
  3.                     Log.e(TAG, "onMapLoaded...")
  4.                 }
  5.  
  6.             })
  7.             //自带放大缩小接口
  8.             setOnCameraChangeListener(object : AMap.OnCameraChangeListener {
  9.                 override fun onCameraChange(p0: CameraPosition?) {
  10.                     //Log.e(TAG, "onCameraChange + ${p0?.toString()}")
  11.                 }
  12.  
  13.                 override fun onCameraChangeFinish(p0: CameraPosition?) {
  14.                     Log.e(TAG, "onCameraChangeFinish + ${p0?.toString()}")
  15.                 }
  16.  
  17.             })
  18.             //map point点击事件
  19.             addOnMapClickListener(object : AMap.OnMapClickListener {
  20.                 override fun onMapClick(p0: LatLng?) {
  21.                     Log.e(TAG, "onMapClick + ${p0?.toString()}")
  22.                 }
  23.  
  24.             })
  25.             //地图自带poi点击事件
  26.             addOnPOIClickListener(object : AMap.OnPOIClickListener {
  27.                 override fun onPOIClick(p0: Poi?) {
  28.                     Log.e(TAG, "onPOIClick + ${p0?.toString()}")
  29.                 }
  30.  
  31.             })
  32.             addOnMarkerClickListener(object : AMap.OnMarkerClickListener {
  33.                 override fun onMarkerClick(p0: Marker?): Boolean {
  34.                     Log.e(TAG, "onMarkerClick + ${p0?.id}")
  35.                     return true
  36.                 }
  37.             })

10、截图功能

拿到bitmap对象进行处理

  1. map?.getMapScreenShot(object : AMap.OnMapScreenShotListener {
  2.     override fun onMapScreenShot(p0: Bitmap?) {
  3.         TODO("Not yet implemented")
  4.     }
  5.  
  6.     override fun onMapScreenShot(p0: Bitmap?, p1: Int) {
  7.         TODO("Not yet implemented")
  8.     }
  9.  
  10. })

五、代码

  1. <?xml version="1.0" encoding="utf-8"?>
  2. <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
  3.     android:layout_width="match_parent"
