做網(wǎng)站 賺錢嗎推廣費(fèi)用一般多少
一、獲取高德平臺(tái)key
【1】基于application包名&sha1值在高德控制臺(tái)獲取key值，詳情參考：? 獲取Key-創(chuàng)建工程-開發(fā)指南-Android 地圖SDK | 高德地圖API
【2】在manifest中聲明權(quán)限
【3】將拿到的key值在manifest中進(jìn)行聲明
<!--允許程序打開網(wǎng)絡(luò)套接字-->
<uses-permission android:name="android.permission.INTERNET" />
<!--允許程序設(shè)置內(nèi)置sd卡的寫權(quán)限-->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<!--允許程序獲取網(wǎng)絡(luò)狀態(tài)-->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<!--允許程序訪問(wèn)WiFi網(wǎng)絡(luò)信息-->
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<!--允許程序訪問(wèn)CellID或WiFi熱點(diǎn)來(lái)獲取粗略的位置-->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <meta-dataandroid:name="com.amap.api.v2.apikey"android:value="xxxxxxxxxxxx" />二、集成依賴
在app build.gradle文件中增加高德地圖依賴
implementation("com.amap.api:3dmap:9.8.2")三、顯示地圖
概述-Android 地圖SDK | 高德地圖API
在xml文件中聲明MapView控件，并在class中重寫?onCreate 方法（此方法必須重寫），注意生命周期的管理
<com.amap.api.maps.MapViewandroid:id="@+id/map"android:layout_width="match_parent"android:layout_height="match_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)
}地圖默認(rèn)中心點(diǎn)為北京天安門
四、高德地圖具體使用
以下對(duì)于地圖的控制使用之前需要拿到AMap對(duì)象
map = mapView?.map1、切換城市中心點(diǎn)
private fun moveCenterTo(latLng: LatLng) {val cameraUpdate = CameraUpdateFactory.newLatLng(latLng)map?.moveCamera(cameraUpdate)
}Android高德地圖切換城市中心點(diǎn)展示
2、設(shè)置縮放級(jí)別
moveCamera(CameraUpdateFactory.zoomTo(14.0f))
3、繪制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 = ArrayList<MarkerOptions>()
list.add(marker1)
list.add(marker2)
map?.addMarkers(list, false)如下圖所示，不設(shè)置icon默認(rèn)展示藍(lán)色定位圖標(biāo)。
11
針對(duì)marker可以設(shè)置的屬性：
| position | 在地圖上標(biāo)記位置的經(jīng)緯度值，必填參數(shù) |
| title | 點(diǎn)標(biāo)記的標(biāo)題 |
| snippet | 點(diǎn)標(biāo)記的內(nèi)容 |
| draggable | 點(diǎn)標(biāo)記是否可拖拽 |
| visible | 點(diǎn)標(biāo)記是否可見(jiàn) |
| anchor | 點(diǎn)標(biāo)記的錨點(diǎn) |
| alpha | 點(diǎn)的透明度 |
public final?java.util.ArrayList<Marker>?addMarkers(java.util.ArrayList<MarkerOptions>?options, boolean?moveToCenter)在地圖上添一組圖片標(biāo)記（marker）對(duì)象，并設(shè)置是否改變地圖狀態(tài)以至于所有的marker對(duì)象都在當(dāng)前地圖可視區(qū)域范圍內(nèi)顯示。
參數(shù):
options?- 多個(gè)markerOptions對(duì)象，它們分別定義了對(duì)應(yīng)marker的屬性信息。
moveToCenter?- 是否改變地圖狀態(tài)，默認(rèn)為false。返回:
返回一組被添加的marker對(duì)象。
4、繪制折線
val latLngList = ArrayList<LatLng>()
latLngList.add(MARKER1)
latLngList.add(MARKER2)
map?.addPolyline(PolylineOptions().addAll(latLngList).width(3f).color(Color.RED)
)
5、軌跡
SmoothMoveMarker(map).apply {
setDescriptor(BitmapDescriptorFactory.fromResource(R.drawable.smooth))setPoints(latLngList)setTotalDuration(5)startSmoothMove()}6、兩點(diǎn)之間距離計(jì)算
AMapUtils.calculateLineDistance(latLng1,latLng2)7、切換地圖圖層
【1】預(yù)設(shè)模式
mapType = AMap.MAP_TYPE_NIGHT【2】在線自定義模式
val options = CustomMapStyleOptions().apply {isEnable = truestyleId = ""
}
map?.setCustomMapStyle(options)8、手勢(shì)交互
map?.uiSettings.let {it.isRotateGesturesEnabled = falseit.isZoomControlsEnabled = falseit.isTiltGesturesEnabled = false
}更多設(shè)置可參考：https://a.amap.com/lbs/static/unzip/Android_Map_Doc/3D/index.html?overview-summary.html
9、地圖狀態(tài)監(jiān)聽(tīng)
setOnMapLoadedListener(object : AMap.OnMapLoadedListener {override fun onMapLoaded() {Log.e(TAG, "onMapLoaded...")}})//自帶放大縮小接口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點(diǎn)擊事件addOnMapClickListener(object : AMap.OnMapClickListener {override fun onMapClick(p0: LatLng?) {Log.e(TAG, "onMapClick + ${p0?.toString()}")}})//地圖自帶poi點(diǎn)擊事件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、截圖功能
拿到bitmap對(duì)象進(jìn)行處理
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")}})五、代碼
