最近比较闲，所以就顺便研究高德地图，原因是之前基本上都用的百度地图，但是百度地图的代码太多了，两字，很烦。
先来个效果图：
蓝色的marker就是点击的，蓝色的圆圈是我当前位置。
apk下载地址：
一些基本操作这里就不多说了，自己去看官方文档，我们这里说一下周边搜索和POI计算距离。
首先定位一下自己当前位置，因为我要拿到当前的位置的经纬度，后面有用：
* 设置一些amap的属性
private void setUpLocation() {
mAMap.setLocationSource(this);
mAMap.getUiSettings().setMyLocationButtonEnabled(true);
mAMap.setMyLocationEnabled(true);
mAMap.setMyLocationType(AMap.LOCATION_TYPE_LOCATE);
* 定位成功后回调函数
public void onLocationChanged(AMapLocation amapLocation) {
if (mListener != null && amapLocation != null) {
if (amapLocation != null
&& amapLocation.getErrorCode() == 0) {
amapLocation.getLocationType();
myLat = amapLocation.getLatitude();
myLongt = amapLocation.getLongitude();
amapLocation.getAccuracy();
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date = new Date(amapLocation.getTime());
df.format(date);
amapLocation.getAddress();
amapLocation.getCountry();
amapLocation.getProvince();
amapLocation.getCity();
amapLocation.getDistrict();
amapLocation.getStreet();
amapLocation.getStreetNum();
amapLocation.getCityCode();
amapLocation.getAdCode();
TextView textView = (TextView) findViewById(R.id.city_detail);
textView.setText(amapLocation.getCity() + "=" + amapLocation.getDistrict() + "==" + amapLocation.getStreetNum());
mListener.onLocationChanged(amapLocation);
String errText = "定位失败," + amapLocation.getErrorCode() + ": " + amapLocation.getErrorInfo();
Log.e("AmapErr", errText);
* 激活定位
public void activate(OnLocationChangedListener listener) {
mListener =
if (mlocationClient == null) {
mlocationClient = new AMapLocationClient(this);
mLocationOption = new AMapLocationClientOption();
mlocationClient.setLocationListener(this);
mLocationOption.setLocationMode(AMapLocationClientOption.AMapLocationMode.Hight_Accuracy);
mlocationClient.setLocationOption(mLocationOption);
mlocationClient.startLocation();
* 停止定位
public void deactivate() {
mListener = null;
if (mlocationClient != null) {
mlocationClient.stopLocation();
mlocationClient.onDestroy();
mlocationClient = null;
可以看到，定位成功之后我们可以拿到任何想要的数据。
一步步来，先初始化一下数据，
* 初始化AMap对象
private void init() {
if (mAMap == null) {
mAMap = mapview.getMap();
mAMap.setOnMapClickListener(this);
mAMap.setOnMarkerClickListener(this);
mAMap.setOnInfoWindowClickListener(this);
mAMap.setInfoWindowAdapter(this);
TextView searchButton = (TextView) findViewById(R.id.btn_search);
searchButton.setOnClickListener(this);
setUpLocation();
locationMarker = mAMap.addMarker(new MarkerOptions()
.anchor(0.5f, 0.5f)
.icon(BitmapDescriptorFactory
.fromBitmap(BitmapFactory.decodeResource(getResources(), R.mipmap.point4)))
.position(new LatLng(myLat, myLongt)));
locationMarker.showInfoWindow();
mAMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(myLat, myLongt), 14));
tvDistance = (TextView) findViewById(R.id.poi_info);
我们可以根据自己想要的去搜索
* 开始进行poi搜索
protected void doSearchQuery() {
keyWord = mSearchText.getText().toString().trim();
currentPage = 0;
query = new PoiSearch.Query(keyWord, "", "");
query.setPageSize(20);
query.setPageNum(currentPage);
LatLonPoint lp = new LatLonPoint(myLat, myLongt);
if (lp != null) {
poiSearch = new PoiSearch(this, query);
poiSearch.setOnPoiSearchListener(this);
poiSearch.setBound(new SearchBound(lp, 10000, true));
poiSearch.searchPOIAsyn();
搜索的结果会在
public void onPoiSearched(PoiResult result, int rcode) 里面来做，如果rcode==1000那就是搜索成功了
public void onPoiSearched(PoiResult result, int rcode) {
if (rcode == AMapException.CODE_AMAP_SUCCESS) {
if (result != null && result.getQuery() != null) {// 搜索poi的结果
if (result.getQuery().equals(query)) {// 是否是同一条
poiResult =
poiItems = poiResult.getPois();// 取得第一页的poiitem数据，页数从数字0开始
List&SuggestionCity& suggestionCities = poiResult
.getSearchSuggestionCitys();// 当搜索不到poiitem数据时，会返回含有搜索关键字的城市信息
if (poiItems != null && poiItems.size() & 0) {
//清除POI信息显示
whetherToShowDetailInfo(false);
//并还原点击marker样式
if (mlastMarker != null) {
resetlastmarker();
//清理之前搜索结果的marker
if (poiOverlay != null) {
poiOverlay.removeFromMap();
mAMap.clear();
poiOverlay = new myPoiOverlay(mAMap, poiItems);
poiOverlay.addToMap();
poiOverlay.zoomToSpan();
mAMap.addMarker(new MarkerOptions()
.anchor(0.5f, 0.5f)
.icon(BitmapDescriptorFactory
.fromBitmap(BitmapFactory.decodeResource(
getResources(), R.mipmap.point4)))
.position(new LatLng(myLat, myLongt)));
mAMap.addCircle(new CircleOptions()
.center(new LatLng(myLat, myLongt)).radius(5000)
.strokeColor(Color.BLUE)
.fillColor(Color.argb(50, 1, 1, 1))
.strokeWidth(2));
} else if (suggestionCities != null
&& suggestionCities.size() & 0) {
showSuggestCity(suggestionCities);
ToastUtil.show(PoiAroundSearchActivity.this,
R.string.no_result);
.show(PoiAroundSearchActivity.this, R.string.no_result);
ToastUtil.showerror(this.getApplicationContext(), rcode);
接下来要做的就是根据搜索到的marker，当用户点击这个marker的时候，就计算出用户当前点击的marker到用户之间的距离。
public boolean onMarkerClick(Marker marker) {
if (marker.getObject() != null) {
whetherToShowDetailInfo(true);
PoiItem mCurrentPoi = (PoiItem) marker.getObject();
if (mlastMarker == null) {
mlastMarker =
// 将之前被点击的marker置为原来的状态
resetlastmarker();
mlastMarker =
detailMarker =
detailMarker.setIcon(BitmapDescriptorFactory
.fromBitmap(BitmapFactory.decodeResource(
getResources(),
R.mipmap.poi_marker_pressed)));
setPoiItemDisplayContent(mCurrentPoi);
} catch (Exception e) {
// TODO: handle exception
whetherToShowDetailInfo(false);
resetlastmarker();
//我的当前位置与点击的marker的距离
LatLng latlngA = new LatLng(myLat, myLongt);
distance = AMapUtils.calculateLineDistance(latlngA, marker.getPosition());
tvDistance.setText("两点间距离为：" + distance + "m");
这里我只是显示十个marker。
怎么把marker添加到地图里面呢，我们自己定义一个类吧，
* 自定义PoiOverlay
private class myPoiOverlay {
private AM
private List&PoiItem& mP
private ArrayList&Marker& mPoiMarks = new ArrayList&Marker&();
public myPoiOverlay(AMap amap, List&PoiItem& pois) {
* 添加Marker到地图中。
public void addToMap() {
for (int i = 0; i & mPois.size(); i++) {
Marker marker = mamap.addMarker(getMarkerOptions(i));
PoiItem item = mPois.get(i);
marker.setObject(item);
mPoiMarks.add(marker);
* 去掉PoiOverlay上所有的Marker。
public void removeFromMap() {
for (Marker mark : mPoiMarks) {
mark.remove();
* 移动镜头到当前的视角。
public void zoomToSpan() {
if (mPois != null && mPois.size() & 0) {
if (mamap == null)
LatLngBounds bounds = getLatLngBounds();
mamap.moveCamera(CameraUpdateFactory.newLatLngBounds(bounds, 100));
private LatLngBounds getLatLngBounds() {
LatLngBounds.Builder b = LatLngBounds.builder();
for (int i = 0; i & mPois.size(); i++) {
b.include(new LatLng(mPois.get(i).getLatLonPoint().getLatitude(),
mPois.get(i).getLatLonPoint().getLongitude()));
return b.build();
private MarkerOptions getMarkerOptions(int index) {
return new MarkerOptions()
.position(
new LatLng(mPois.get(index).getLatLonPoint()
.getLatitude(), mPois.get(index)
.getLatLonPoint().getLongitude()))
.title(getTitle(index)).snippet(getSnippet(index))
.icon(getBitmapDescriptor(index));
protected String getTitle(int index) {
return mPois.get(index).getTitle();
protected String getSnippet(int index) {
return mPois.get(index).getSnippet();
* 从marker中得到poi在list的位置。
* marker 一个标记的对象。
* 返回该marker对应的poi在list的位置。
public int getPoiIndex(Marker marker) {
for (int i = 0; i & mPoiMarks.size(); i++) {
if (mPoiMarks.get(i).equals(marker)) {
return -1;
* 返回第index的poi的信息。
* index 第几个poi。
* poi的信息。poi对象详见搜索服务模块的基础核心包（com.amap.api.services.core）中的类 &strong&&a href="../../../../../../Search/com/amap/api/services/core/PoiItem.html" title="com.amap.api.services.core中的类"&PoiItem&/a&&/strong&。
public PoiItem getPoiItem(int index) {
if (index & 0 || index &= mPois.size()) {
return null;
return mPois.get(index);
protected BitmapDescriptor getBitmapDescriptor(int arg0) {
if (arg0 & 10) {
BitmapDescriptor icon = BitmapDescriptorFactory.fromBitmap(
BitmapFactory.decodeResource(getResources(), markers[arg0]));
BitmapDescriptor icon = BitmapDescriptorFactory.fromBitmap(
BitmapFactory.decodeResource(getResources(), R.mipmap.marker_other_highlight));
