Study Notes for Android: Baidu map (Search Service)

Baidu map mobile edition API integrated search services include: location search, peripheral search, range search, bus search, driving and walking search. By initializing the mksearch class, register the listening object mksearchlistener for the search results, implement Asynchronous search service. First, customize mysearchlistener to implement the mksearchlistener interface. Different callback methods are used to obtain the search results:

public class MySearchListener implements MKSearchListener {    @Override    public void onGetAddrResult(MKAddrInfo result, int iError) {    }     @Override    public void onGetDrivingRouteResult(MKDrivingRouteResult result, int iError) {    }     @Override    public void onGetPoiResult(MKPoiResult result, int type, int iError) {    }     @Override    public void onGetTransitRouteResult(MKTransitRouteResult result, int iError) {    }     @Override    public void onGetWalkingRouteResult(MKWalkingRouteResult result, int iError) {    }}

Then initialize the mksearch class:

Mksearch = new mksearch (); mksearch. INIT (mapmanager, new mysearchlistener (); // note that only one mksearchlistener is supported. The last setting prevails.

Knowledge Used by the Search Service: mksearch

It is used for location search, peripheral search, range search, bus search, driving car search, and walking search.
