Well, today we will bring you three technical points,

First technical point: Route

Based on our previous experience, we need to add the following search code to the oncreate method in the first step of searching for a route.

// 6.0 search for the route // mapcontroller. setzoom (12); // search for objects within the MAP range // mksearch = new mksearch (); // mksearch. init (bmapmanager, new mysearchlistener (); // specify the first coordinate // start = new mkplannode (); // start.pt = new geopoint (INT) (39.915*1e6), (INT) (116.404*1e6); // specify the Second coordinate. // end = new mkplannode (); // end.pt = new geopoint (40057031,2017307852); // method for setting the callback route // mksearch. walkingsearch (null, start, null, end );

Then define a mysearchlistener implements mksearchlistener

Implement the ongetwalkingrouteresult method in the interface

@ Overridepublic void ongetwalkingrouteresult (mkwalkingrouteresult result, int type) {// calls back the called search method and responds if (result = NULL) {return ;} routeoverlay = new routeoverlay (baidu_suyiactivity.this, mapview); routeoverlay. setdata (result. getplan (0 ). getroute (0); mapview. getoverlays (). add (routeoverlay); // refresh the map mapview. invalidate ();}

Second technical point: Bus Transfer route

The first step and the second step

// 7.0 search for the bus transfer route // mapcontroller. setzoom (12); // search for objects within the MAP range // mksearch = new mksearch (); // mksearch. init (bmapmanager, new mysearchlistener (); // specify the first coordinate // start = new mkplannode (); // start.pt = new geopoint (INT) (39.915*1e6), (INT) (116.404*1e6); // specify the Second coordinate. // end = new mkplannode (); // end.pt = new geopoint (40057031,2017307852); // method for setting the callback route // mksearch. transitsearch ("Beijing", start, end );

@ Overridepublic void ongettransitrouteresult (mktransitrouteresult result, int type) {// callback method of public transit transfer if (result = NULL) {return;} transitoverlay = new transitoverlay (transport, mapview); transitoverlay. setdata (result. getplan (0); mapview. getoverlays (). add (transitoverlay); // refresh the map mapview. invalidate ();}

Third technical point: Bus Route details

The search of bus routes is a little more complex.

The first step remains unchanged.

// 8.0 search mapcontroller for the bus route details. setzoom (12); // search for objects within the MAP range mksearch = new mksearch (); mksearch. init (bmapmanager, new mysearchlistener (); // method for setting the callback route mksearch. poisearchincity ("Beijing", "300 ");

Step 2 first implement this method in the interface

@ Overridepublic void ongetpoiresult (mkpoiresult result, int type, int ierror) {// callback response to the called search method // v8.00if (result = NULL | ierror! = 0) {toast. maketext (baidu_suyiactivity.this, "sorry, you cannot find the result", 2 ). show (); Return ;}// define a bus route map description class mkpoiinfo = NULL; // get the bus route map's total site int totalpoinum = result. getnumpois (); For (INT I = 0; I <totalpoinum; I ++) {mkpoiinfo = result. getpoi (I); If (mkpoiinfo. epoitype = 2) {break; // if the road map of the bus is returned, return} mksearch. buslinesearch ("Beijing", mkpoiinfo. UID );}

Step 3 and then implement the following method

@ Overridepublic void ongetaddrresult (mkaddrinfo arg0, int arg1) {}@ overridepublic void ongetbusdetailresult (mkbuslineresult result, int type) {If (result = NULL | type! = 0) {toast. maketext (baidu_suyiactivity.this, "sorry, you cannot find the result", 2 ). show (); return;} routeoverlay = new routeoverlay (baidu_suyiactivity.this, mapview); routeoverlay. setdata (result. getbusroute (); // clear all bus information mapview. getoverlays (). clear (); mapview. getoverlays (). add (routeoverlay); mapview. invalidate (); mapview. getcontroller (). animateto (result. getbusroute (). getstart ());}

This completes the three knowledge points.
