Currently, the latest jar: AMap_Search_V5.7.0_20171229.jar can be downloaded from the official website.

2. Create an object class, which contains four parameters used to describe vertex information-MarketBean

Public class MarketBean {/***** latitude */private double latitude;/***** longitude */private double longpolling;/***** title */private String; /*** content */private String content; public double getLatitude () {return latitude;} public void setLatitude (double latitude) {this. latitude = latitude;} public double getlongpolling () {return longpolling;} public void setlongpolling (double longpolling) {this. longpolling = longpolling;} public String get () {return;} public void set (String) {this. =;} public String getContent () {return content;} public void setContent (String content) {this. content = content;} public MarketBean (double latitude, double longpolling, String, String content) {this. latitude = latitude; this. longpolling = longpolling; this. =; this. content = content ;}}

It can be called during initialization.

/*** Add multiple markets */private List
 
  
MarketList; private void addMoreMarket () {if (marketList = null) {marketList = new ArrayList <> () ;}// simulate 6 false data marketlists. add (new MarketBean (22.675, 114.028, "Title 1", "content 1"); marketList. add (new MarketBean (22.694, 114.099, "title 2", "content 2"); marketList. add (new MarketBean (22.667, 114.041, "Title 3", "content 3"); marketList. add (new MarketBean (22.647, 114.023, "Title 4", "content 4"); marketList. add (new MarketBean (22.688, 114.066, "Title 5", "content 5"); marketList. add (new MarketBean (22.635, 114.077, "Title 6", "content 6"); for (int I = 0; I <marketList. size (); I ++) {aMap. addMarker (new MarkerOptions (). anchor (1.5f, 3.5f ). position (new LatLng (marketList. get (I ). getLatitude (), // set the latitude marketList. get (I ). getlongpolling () // sets the longitude. (marketList. get (I ). get () // set the title. snippet (marketList. get (I ). getContent () // set content //. setFlat (true) // set the Marker to show the location. You can view the effect on the double-finger drop-down map. draggable (true) // set the Marker to be dragged. icon (BitmapDescriptorFactory. fromResource (R. mipmap. ic_launcher);} // sets the custom pop-up window aMap. setInfoWindowAdapter (new WindowAdapter (this); // bind the Information Window and click event aMap. setOnInfoWindowClickListener (new WindowAdapter (this); aMap. setOnMarkerClickListener (new WindowAdapter (this ));}
 

Custom pop-up window (all content updates after custom InfoWindow need to be completed by the user)-WindowAdapter

Public class WindowAdapter implements AMap. infoWindowAdapter, AMap. onMarkerClickListener, AMap. onInfoWindowClickListener {private Context context; private static final String TAG = "WindowAdapter"; public WindowAdapter (Context context) {this. context = context ;}@ Override public View getInfoWindow (Marker marker) {// View of the associated layout = LayoutInflater. from (context ). inflate (R. layout. layout_info_item, null); // Title TextView = (TextView) view. findViewById (R.id.info _); // address information TextView address = (TextView) view. findViewById (R.id.info _ address); // latitude TextView latitude = (TextView) view. findViewById (R.id.info _ latitude); // longitude TextView longpolling = (TextView) view. findViewById (R.id.info _ longpolling );. setText (marker. get (); address. setText (marker. getSnippet (); latitude. setText (marker. getPosition (). latitude + ""); longpolling. setText (marker. getPosition (). longpolling + ""); Log. e (TAG, "getInfoWindow1:" + marker. get (); Log. e (TAG, "getInfoWindow:" + marker. getSnippet (); Log. e (TAG, "getInfoWindow:" + marker. getPosition (). latitude); Log. e (TAG, "getInfoWindow:" + marker. getPosition (). longpolling); return view;} // if you use a custom layout, you do not need to use this method. return null @ Override public View getInfoContents (Marker marker) {return null ;} // interface called back when the marker object is clicked // return true indicates that the interface has responded to the event; otherwise, false @ Override public boolean onMarkerClick (Marker marker) {Log. e (TAG, "Marker clicked"); return false;} // bind Information Window Click Event @ Override public void onInfoWindowClick (Marker marker) {Log. e (TAG, "InfoWindow clicked ");}}

Layout file-layout_info_item

Note that you must set the background style (color and image) of InfoWindow. Otherwise, the default background of autonavi is used.

3. uncode coordinates and address translation-(retrieve the current location information from any point on the mobile map)

Map slide listening event:

// Sliding listener aMap. setOnCameraChangeListener (new AMap. onCameraChangeListener () {// latitude and longitude @ Override public void onCameraChange (CameraPosition cameraPosition) {// longitude double longdistance = cameraPosition.tar get. longpolling; // latitude double latitude = cameraPosition.tar get. latitude; Log. e (TAG, "onCameraChange sliding:" + longpolling); Log. e (TAG, "onCameraChange slide:" + latitude);} // latitude and longitude at the end of the slide @ Override public void onCameraChangeFinish (CameraPosition cameraPosition) {// longitude double longpolling = cameraPosition.tar get. longpolling; // latitude double latitude = cameraPosition.tar get. latitude; // the longitude and latitude coordinates at the end of the input. getAddressByLatLonPoint (new LatLonPoint (latitude, longpolling); Log. e (TAG, "onCameraChangeFinish sliding end:" + longpolling); Log. e (TAG, "onCameraChangeFinish slide end:" + latitude );}});} /*** uncode coordinates to address * RegeocodeQuery [Coordinate to address] * GeocodeQuery [Address to coordinate] */private void getAddressByLatLonPoint (final LatLonPoint latLonPoint) {GeocodeSearch geocodeSearch = new GeocodeSearch (this); // a parameter indicates the latitude and longitude, And a two parameter indicates the range of meters, the three parameters indicate the map coordinate system or the GPS coordinate system RegeocodeQuery regeocodeQuery = new RegeocodeQuery (latLonPoint, 2000, GeocodeSearch. AMAP); geocodeSearch. getFromLocationAsyn (regeocodeQuery); // address indicates the address, and the second parameter indicates the city to be queried. You can search both Chinese and Chinese. citycode and adcode are OK GeocodeQuery query = new GeocodeQuery ("Ganzhou City ", "Ganzhou City"); geocodeSearch. getFromLocationNameAsyn (query); // listens to geocodeSearch for the results of the inverse geographic code. setOnGeocodeSearchListener (new GeocodeSearch. onGeocodeSearchListener () {@ Override public void onRegeocodeSearched (RegeocodeResult regeocodeResult, int I) {// if I = 1000) {RegeocodeAddress regeocodeAddress = success. getRegeocodeAddress (); // the location of the current map center (for other information, see regeocodeAddress.) String formatAddress = regeocodeAddress. getFormatAddress (); address. setText (formatAddress); Log. e (TAG, "onCameraChange address for latitude/longitude conversion:" + formatAddress);} else {Log. e (TAG, "No information here...: ") ;}@ Override public void onGeocodeSearched (GeocodeResult geocodeResult, int I) {if (I = 1000) {Log. e (TAG, "onCameraChange query address:" + geocodeResult. getGeocodeQuery (). getLocationName (); Log. e (TAG, "City of onCameraChange query:" + geocodeResult. getGeocodeQuery (). getCity (); Log. e (TAG, "latitude of onCameraChange query:" + geocodeResult. getGeocodeAddressList (). get (0 ). getLatLonPoint (). getLatitude (); Log. e (TAG, "onCameraChange query longitude:" + geocodeResult. getGeocodeAddressList (). get (0 ). getLatLonPoint (). getlongpolling ();} else {Log. e (TAG, "query failed... :");}}});}

Address. setText (formatAddress); add a TextView in the layout and initialize it.
