首先去百度开放平台申请应用AK,然后放入自己的项目中。

            android:name="com.baidu.lbsapi.API_KEY"android:value="kGaoZOpl7hCvKqsN3xpz432Zfzyqtxlp" />

导入百度sdk的引用资源

具体资源可以从demo里面下载

配置定位及检索需要的权限

         <uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /><uses-permission android:name="android.permission.CHANGE_WIFI_STATE" /><uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /><uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.READ_PHONE_STATE" /><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /><uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /><uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" /><serviceandroid:name="com.baidu.location.f"android:enabled="true"android:process=":remote" />

在自定义application初始化

 SDKInitializer.initialize(this)SDKInitializer.setCoordType(CoordType.BD09LL)

直接代码实现

动态获取定位需要的权限，开始定位

  mLocationClient = LocationClient(applicationContext)mLocationClient!!.registerLocationListener(MyLocationListener())val option = LocationClientOption()option.locationMode = LocationClientOption.LocationMode.Hight_Accuracyoption.setIsNeedAddress(true)option.setIsNeedLocationPoiList(true)option.isOpenGps = truemLocationClient!!.locOption = option

实现定位监听，并初始化地图显示出界面

 private inner class MyLocationListener : BDLocationListener {override fun onReceiveLocation(location: BDLocation) {//获取定位结果if (!TextUtils.isEmpty(location.city)) {mLatLng = LatLng(location.latitude, location.longitude)initData(location.latitude, location.longitude)mSelectCity = location.cityif (mSelectCity.endsWith("市")) {mSelectCity = mSelectCity.substring(0, mSelectCity.length - 1)}tv_city.text=location.citymLocationClient!!.stop()} else {doLocation()mLocationClient!!.start()}}}

初始化地图并监听手指滑动回调

     //第一次定位，默认要用MapUtil.gcj02_To_Bd09()转换经纬度private fun initData(latitude: Double, longitude: Double, isSearch: Boolean? = false) {mBaiduMap = mapView.mapval location = MapUtil.gcj02_To_Bd09(latitude,longitude)mCenter = LatLng(latitude, longitude)val centerPoint =if (isSearch!!) LatLng(latitude, longitude) else LatLng(location[0], location[1])val mapStatus = MapStatus.Builder().apply {target(centerPoint)zoom(19f)}val mMapStatusUpdate = MapStatusUpdateFactory.newMapStatus(mapStatus.build())
//        val mMapStatusUpdate = MapStatusUpdateFactory.newLatLngZoom(mCenter, 18f)mBaiduMap!!.setMapStatus(mMapStatusUpdate)mBaiduMap!!.setOnMapLoadedCallback {reverseRequest(mCenter)}mBaiduMap!!.setOnMapStatusChangeListener(object : BaiduMap.OnMapStatusChangeListener {override fun onMapStatusChangeStart(p0: MapStatus?) {}override fun onMapStatusChangeStart(p0: MapStatus?, p1: Int) {}override fun onMapStatusChange(p0: MapStatus?) {}override fun onMapStatusChangeFinish(mapStatus: MapStatus?) {val newCenter: LatLng = mapStatus!!.target// 如果是点击poi item导致的地图状态更新，则不用做后面的逆地理请求，if (mStatusChangeByItemClick) {if (!Utils.isLatlngEqual(mCenter, newCenter)) {mCenter = newCenter}mStatusChangeByItemClick = falsereturn}if (mCenter != null) {if (!Utils.isLatlngEqual(mCenter, newCenter)) {mCenter = newCenterreverseRequest(mCenter)}} else {mCenter = newCenterreverseRequest(mCenter)}}})}

3.逆地理编码请求，同时获取中心点位置附近poi列表

 /*** 逆地理编码请求** @param latLng*/private fun reverseRequest(latLng: LatLng?) {if (null == latLng) {return}setMarker()val reverseGeoCodeOption = ReverseGeoCodeOption().location(latLng).newVersion(1) // 建议请求新版数据.radius(sDefaultRGCRadius)if (null == mGeoCoder) {mGeoCoder = GeoCoder.newInstance()}mGeoCoder!!.setOnGetGeoCodeResultListener(object : OnGetGeoCoderResultListener {override fun onGetGeoCodeResult(p0: GeoCodeResult?) {}override fun onGetReverseGeoCodeResult(reverseGeoCodeResult: ReverseGeoCodeResult?) {val curAddressPoiInfo = PoiInfo()curAddressPoiInfo.address = reverseGeoCodeResult!!.addresscurAddressPoiInfo.location = reverseGeoCodeResult!!.location//经纬度转化地址val poiInfos = reverseGeoCodeResult!!.poiListpoiBeans.clear()var poiAddressBean: PoiAddressBeanif (poiInfos != null && !"".equals(poiInfos)) {for (poi in poiInfos) {poiAddressBean = PoiAddressBean()poiAddressBean.address = poi.addresspoiAddressBean.name = poi.namepoiAddressBean.location = poi.locationpoiBeans.add(poiAddressBean)Log.i("zyy",poi.toString())}}poiAdapter!!.notifyDataSetChanged()}})mGeoCoder!!.reverseGeoCode(reverseGeoCodeOption)}

设置marker

private fun setMarker() {val projection: Projection = mBaiduMap!!.projection ?: return//定义Maker坐标点val point = projection.toScreenLocation(mCenter)//构建Marker图标val bitmap = BitmapDescriptorFactory.fromResource(R.drawable.icon_address)/* 构建MarkerOption，用于在地图上添加Marker */val option = MarkerOptions().position(mCenter).icon(bitmap).flat(false).fixedScreenPosition(point)//在地图上添加Marker，并显示mBaiduMap!!.addOverlay(option)bitmap.recycle()}

设置编辑框搜索SuggestionSearch

 private fun initSuggestions() {mSuggestionSearch = SuggestionSearch.newInstance()mSuggestionSearch.setOnGetSuggestionResultListener(object : OnGetSuggestionResultListener {override fun onGetSuggestionResult(suggestionResult: SuggestionResult?) {if (suggestionResult?.allSuggestions == null) {return}mSuggestionInfos.clear();//清空数据列表val suggestionInfoList = suggestionResult.allSuggestionsif (suggestionInfoList != null) {for (info in suggestionInfoList) {if (info.pt != null) {//过滤没有经纬度信息的mSuggestionInfos.add(info)}}}sugAdapter!!.notifyDataSetChanged();}})}

监听文本框搜索

et_search.addTextChangedListener(object : TextWatcher {override fun afterTextChanged(s: Editable?) {}override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {}override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {if (s!!.isEmpty()) {rcv_search.visibility = View.GONEreturn}rcv_search.visibility = View.VISIBLEmSuggestionSearch.requestSuggestion((SuggestionSearchOption()).citylimit(true).keyword(s.toString()).city(mSelectCity));}})

整个功能差不多已经完结，可以完成搜索、滑动地图检索poi

 //底部poi检索adapterprivate fun initAdapter() {poiAdapter = SearchPoiAdapter(poiBeans)rcv_nearby.layoutManager = LinearLayoutManager(this)rcv_nearby.adapter = poiAdapterpoiAdapter!!.setOnItemClickListener { adapter, view, position ->val bean = poiBeans[position]poiAdapter!!.updateStatus(bean.name)makeText(this, bean.address, LENGTH_SHORT).show()}}

 //关键字列表private fun initSearchAdapter() {sugAdapter = MapSearchAdapter(mSuggestionInfos)rcv_search.layoutManager = LinearLayoutManager(this)rcv_search.adapter = sugAdaptersugAdapter!!.setOnItemClickListener { adapter, view, position ->val info = mSuggestionInfos[position]initData(info.pt!!.latitude, info.pt!!.longitude, true)et_search.setText("")hideSoftInput(et_search)rcv_search.visibility = View.GONE}}
