Android Baidu Map of the bus line details search _android

This article can realize Baidu bus line search, you can select more than one line, the specific implementation code as follows:

First, the bus route details search

The details of the bus line are mainly divided into two steps, 1. Get the uid,2 of the bus line. Get the details of the bus line by UID.

1. Get the UID of the bus line:

     * * Obtain the UID of the bus route map and initiate the search for details of the bus line based on the UID
     * * @see *
     Com.baidu.mapapi.mksearchlistener#ongetpoiresult ( Com.baidu.mapapi
     *. Mkpoiresult, int, int)
     *
    /@Override public
    void Ongetpoiresult (Mkpoiresult arg0, int arg1, int arg2) {
      / /TODO auto-generated Method Stub
      if (arg0 = null | | | arg2!= 0) {
        toast.maketext (mainactivity.this, "No results found", 1) ;
        return;
      }
      Define a bus line description class
      mkpoiinfo mkpoiinfo = null;
      Get this time love you the total site of the bus line
      int totalpoinum = Arg0.getnumpois ();
      for (int i = 0; i < Totalpoinum i++) {
        mkpoiinfo = Arg0.getpoi (i);
        if (Mkpoiinfo.epoitype = = 2) {break
          ;
        }
      }
      Mksearch.buslinesearch ("Kaifeng", Mkpoiinfo.uid);
    }

2. Get Bus line details:

* *
     to obtain details of the bus route map * *
     @see *
     com.baidu.mapapi.mksearchlistener#ongetbusdetailresult (com.baidu).
     * Mapapi. Mkbuslineresult, int)
     *
    /@Override public
    void Ongetbusdetailresult (Mkbuslineresult arg0, int arg1) {
      //TODO auto-generated method Stub
      if (arg0 = null | | | arg1!= 0) {
        toast.maketext (mainactivity.this, "no Knot found Fruit ", 1);
        return;
      }
      Routeoverlay routeoverlay = new Routeoverlay (mainactivity.this,
          mapview);
      Routeoverlay.setdata (Arg0.getbusroute ())//Get Bus line

      mapview.getoverlays (). Clear ()//clearly identify
      the bus site Mapview.getoverlays (). Add (routeoverlay);
      Mapview.invalidate ();
      Use animated form to describe the bus site
      mapview.getcontroller (). Animateto (Arg0.getbusroute (). Getstart ());
    

When querying, just provide city name and line

Mksearch.poisearchincity ("Kaifeng", "3");

Two, multiple line display

Displaying multiple navigation lines on the same map only needs to be done in two steps,

1. Define Start point End

start = new Mkplannode ();
    start.pt = new Geopoint ((int) (39.915 * 1E6), (int) (116.404 * 1E6));
    end = new Mkplannode ();
    end.pt = new Geopoint (40057031, 116307852);

    Mksearch.transitsearch ("Beijing", Start, end);

2. Circulate all the circuit details on the map

@Override public
    void Ongettransitrouteresult (Mktransitrouteresult arg0, int arg1) {
      //TODO auto-generated Method Stub
      if (arg0 = = null) {return
        ;
      }
      int plannum = Arg0.getnumplan ();//Get all driving routes for
      (int i = 0; i < Plannum; i++) {
        Transitoverlay overlay = new T Ransitoverlay (Mainactivity.this,
            mapview);
        Overlay.setdata (Arg0.getplan (i));
        Mapview.getoverlays (). Add (overlay);
      Mapview.invalidate ();
      Mapview.getcontroller (). Animateto (Arg0.getstart (). PT);
