标记位置未更新

Question

我是Android的新手。我正在使用许多硬编码的经纬度来安装android map.I已经将经纬度存储在arraylist中。有两个标记 - Bus和Student.I必须将Bus标记拖动到纬度每10秒后经度位置应该保持在最后位置，但我的标记没有更新到该位置。

public class TransportBusMapActivity extends AppCompatActivity implements OnMapReadyCallback {

private GoogleMap map;
  // The minimum distance to change Updates in meters
private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 10; // 100 meters

// The minimum time between updates in milliseconds
private static final long MIN_TIME_BW_UPDATES = 10000; // 10 sec
LatLngBounds.Builder builder;
CameraUpdate cu;
int count=0;

ArrayList<LatLng> locations = new ArrayList();
 @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.transport_bus_map);
    locations.add(new LatLng(28.6311812, 77.3785497));
    locations.add(new LatLng(28.6310870, 77.3796440));
    locations.add(new LatLng(28.631012, 77.3805697));
    locations.add(new LatLng(28.627462, 77.3838835));
    locations.add(new LatLng(28.631107, 77.384071));

            /**
     * function to load map. If map is not created it will create it for you
     **/
    SupportMapFragment mapFragment = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map));
    mapFragment.getMapAsync(this);

@Override
public void onMapReady(GoogleMap googleMap) {
    map=googleMap;
    /**clear the map before redraw to them*/
    map.clear();
    /**Create dummy Markers List*/
     List<Marker> markersList = new ArrayList<Marker>();
    //if(locations!=null)
  final Marker Bus = map.addMarker(new MarkerOptions().position(new LatLng(28.6311812, 77.3785497)).title("Bus"));
    Marker Student = map.addMarker(new MarkerOptions().position(new LatLng(
            28.631107, 77.384071)).title("Student"));

    markersList.add(Bus);

    final Handler h = new Handler();
    h.postDelayed(new Runnable() {

                      @Override
                      public void run() {

                          for (int i = 0; i <locations.size(); i++) {
                                                     LatLng currentPosition = locations.get(i);
                              Bus.setPosition(currentPosition);
                              CameraUpdate mLoc = CameraUpdateFactory.newCameraPosition(new CameraPosition.Builder().target(currentPosition).build());
                              map.moveCamera(mLoc);
                                                                  h.postDelayed(this, MIN_TIME_BW_UPDATES);

                      }}
                  },MIN_TIME_BW_UPDATES);


            markersList.add(Student);

    /**create for loop for get the latLngbuilder from the marker list*/
    builder = new LatLngBounds.Builder();
    for (Marker m : markersList) {
        builder.include(m.getPosition());
    }
    /**initialize the padding for map boundary*/
    int padding = 50;
    /**create the bounds from latlngBuilder to set into map camera*/
    LatLngBounds bounds = builder.build();
    /**create the camera with bounds and padding to set into map*/
    cu = CameraUpdateFactory.newLatLngBounds(bounds, padding);

    /**call the map call back to know map is loaded or not*/

    map.setOnMapLoadedCallback(new GoogleMap.OnMapLoadedCallback() {
        @Override
        public void onMapLoaded() {
            /**set animated zoom camera into map*/
            map.animateCamera(cu);
        }
    });
