1.簡介
實(shí)現(xiàn)從地圖上進(jìn)行地理位置的選擇读第，包含地圖拖動(dòng)停止時(shí)边篮，周邊位置的檢索以及輸入關(guān)鍵字的檢索
2.簡單實(shí)現(xiàn)步驟
2.1 地圖sdk導(dǎo)入
根據(jù)百度官方文檔導(dǎo)入sdk以及相關(guān)初始化操作
2.2 定位
private var locationClient: LocationClient? = null
/**
* 定位
*/
private fun getLocation() {
locationClient = LocationClient(applicationContext)
val locationClientOption = LocationClientOption().apply {
openGps = true
setIsNeedAddress(true)
setIsNeedLocationDescribe(true)
}
locationClient?.locOption = locationClientOption
locationClient?.registerLocationListener(locationListener)
locationClient?.start()
}
2.3 根據(jù)定位回調(diào)將地圖中心點(diǎn)移動(dòng)到定位的當(dāng)前位置
/**
* 定位回調(diào)
*/
private val locationListener = object : BDAbstractLocationListener() {
override fun onReceiveLocation(p0: BDLocation?) {
p0?.let {
tvLocation.text = it.city
//移動(dòng)地圖中心點(diǎn)到定位的位置
val statusBuilder =
MapStatus.Builder().target(LatLng(it.latitude, it.longitude)).zoom(17f)
baiduMap?.animateMapStatus(MapStatusUpdateFactory.newMapStatus(statusBuilder.build()))
}
}
}
2.4 定位成功后弊仪，poi周邊檢索
使用關(guān)鍵字以及經(jīng)緯度和搜索半徑去檢索周邊
// 周邊搜索
private var poiSearch: PoiSearch = PoiSearch.newInstance()
// 設(shè)置檢索回調(diào)
poiSearch.setOnGetPoiSearchResultListener(poiSearchResultListener)
/**
* 周邊poi檢索
*/
private var poiSearchResultListener = object : OnGetPoiSearchResultListener {
override fun onGetPoiIndoorResult(p0: PoiIndoorResult?) {
}
override fun onGetPoiResult(result: PoiResult?) {
if (result == null || result.error == SearchResult.ERRORNO.RESULT_NOT_FOUND) {
Toast.makeText(this@ChooseAddressActivity, "未找到結(jié)果", Toast.LENGTH_LONG).show()
return
}
if (result.error == SearchResult.ERRORNO.NO_ERROR) {
result.let {
poiResultAdapter.setData(it.allPoi)
}
}
}
override fun onGetPoiDetailResult(p0: PoiDetailResult?) {
}
override fun onGetPoiDetailResult(p0: PoiDetailSearchResult?) {
}
}
/**
* 根據(jù)經(jīng)緯度進(jìn)行周邊檢索
*/
private fun poiSearch(latLng: LatLng) {
val searchOption = PoiNearbySearchOption().keyword("辦公樓\$商場\$商鋪\$菜場\$批發(fā)市場\$超市\(zhòng)$酒店\$飯店")
.location(latLng)
.radius(1000)
.pageNum(0)
.pageCapacity(20)
.radiusLimit(false)
.scope(2)
poiSearch.searchNearby(searchOption)
}
2.5 移動(dòng)地圖
當(dāng)停止移動(dòng)地圖后汰寓，根據(jù)停止后的經(jīng)緯度去查詢周邊
baiduMap?.setOnMapStatusChangeListener(object : BaiduMap.OnMapStatusChangeListener {
override fun onMapStatusChangeStart(p0: MapStatus?) {
}
override fun onMapStatusChangeStart(p0: MapStatus?, p1: Int) {
}
override fun onMapStatusChange(p0: MapStatus?) {
}
override fun onMapStatusChangeFinish(p0: MapStatus?) {
log("change finished")
p0?.let {
poiSearch(it.target)
}
markerIcon?.let {
it.setAnimation(getTransformationPoint())
it.startAnimation()
}
}
})
2.6 關(guān)鍵字搜索
關(guān)鍵字搜索時(shí)菊碟，根據(jù)輸入的城市以及關(guān)鍵字進(jìn)行poi搜索裕照，監(jiān)聽輸入框的文字實(shí)現(xiàn)即時(shí)搜索
//推薦搜索
private val suggestionSearch: SuggestionSearch = SuggestionSearch.newInstance()
suggestionSearch.setOnGetSuggestionResultListener {
if (it.allSuggestions?.isNotEmpty() == true) {
val list = mutableListOf<PoiInfo>()
it.allSuggestions.forEach {
list.add(PoiInfo().apply {
name = it.key
address = it.address
location = it.getPt()
city = it.city
area = it.district
})
}
searchResultAdapter.setData(list)
}
}
etKey.addTextChangedListener(onTextChanged = { text, _, _, _ ->
println("text changed")
if (TextUtils.isEmpty(text)) {
recyclerSearch.visibility = View.GONE
btnSearch.visibility = View.GONE
} else {
recyclerSearch.visibility = View.VISIBLE
btnSearch.visibility = View.VISIBLE
suggestionSearch.requestSuggestion(
SuggestionSearchOption().keyword(text.toString())
.city(tvLocation.text.toString())
)
}
})
