Learning to write interface callbacks

When do Baidu map anti-geocoding (coordinates to address),

You need to write a result interface callback, usually in the network request, click the event, as well as some asynchronous operation, need to use the interface callback.

Position Manager, there is a position monitoring:

/*** Write your own location Manager * Created by XHJ on 16-1-27.*/ Public classTrackerlocationmanager {protectedTrackerlocationmanager () {}/*** Example of location Manager*/    Private StaticTrackerlocationmanager instance;  Public StaticTrackerlocationmanager getinstance () {if(Instance = =NULL) {instance=NewTrackerlocationmanager (); }        returninstance; }    /*** Reverse geo-coded monitoring*/     Public InterfaceTrackergeocoderlistener {/**to be replicated, get the results of the anti-geocoding*/        voidGetResult (reversegeocoderesult result); }    /*** Reverse geo-coded monitoring*/Trackergeocoderlistener Trackerlistener; /*** Set up reverse code monitoring*/     Public voidSettrackergeocoderlistener (Trackergeocoderlistener listener) { This. Trackerlistener =Listener; }    /*** Get inverse = geocoding Results * *@paramlatlng latitude and longitude *@return     */     Public voidgetpicaddress (latlng latlng) {GeoCoder Msearch=geocoder.newinstance (); /**geo-coded retrieval listener*/        FinalOngetgeocoderresultlistener listener =NewOngetgeocoderresultlistener () { Public voidOngetgeocoderesult (geocoderesult result) {} @Override Public voidOngetreversegeocoderesult (reversegeocoderesult result) {if(Result = =NULL|| Result.error! =SearchResult.ERRORNO.NO_ERROR) {                    //No search results foundLOG.D ("Alan", "No results retrieved--reverse")); } Else {                    //Get reverse geocoding resultsTrackerlistener.getresult (Result),//Executes the GetResult method into the listener and executes the GetResult method to the subclass}            }        };        Msearch.setongetgeocoderesultlistener (listener); Msearch.reversegeocode (Newreversegeocodeoption (). Location (LATLNG));//Perform reverse coding,Getting results in Ongetreversegeocoderesult

} }

This is another class in which the invocation of a method that obtains a reverse geocoding and the implementation of an interface

Trackerlocationmanager Trackerlocationmanager = trackerlocationmanager.getinstance ();            Trackerlocationmanager.settrackergeocoderlistener (Mygeocoderlistener);            Trackerlocationmanager.getpicaddress (Latlist.get (j));//Get Reverse geocoding
