Mover marcador con gps en google map android

Question

Quiero mover el marcador en GOOGLE MAP mientras la ubicación gps cambia como en la aplicación UBER . He encontrado algunas soluciones, pero no he podido resolver mi problema. Las soluciones son 1 y 2

A continuación está mi método onLocationChange()

public void onLocationChanged(Location location) {

    double lattitude = location.getLatitude();
    double longitude = location.getLongitude();

    mLastLocation = location;
    if (mCurrLocationMarker != null) {
        mCurrLocationMarker.remove();
    }
    //Place current location marker
    LatLng latLng = new LatLng(lattitude, longitude);
    MarkerOptions markerOptions = new MarkerOptions();
    markerOptions.position(latLng);
    markerOptions.title("I am here");
    markerOptions.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_RED));

    mCurrLocationMarker = mGoogleMap.addMarker(markerOptions);

    tv_loc.append("Lattitude: " + lattitude + "  Longitude: " + longitude);

    //move map camera
    mGoogleMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
    mGoogleMap.animateCamera(CameraUpdateFactory.zoomTo(15));

    //stop location updates
    if (mGoogleApiClient != null) {
        LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, this);
    }

}

Actualización 1 (Reeditado)

Para obtener más información, agrego más código, pero primero quiero decir que estoy usando pestañas en mi aplicación. La primera tab es de mi mapa. Entonces estoy usando fragmentos para eso.

public class MyLocation extends Fragment implements OnMapReadyCallback, GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener,
LocationListener{

GoogleMap mGoogleMap;
SupportMapFragment mapFrag;
LocationRequest mLocationRequest;
GoogleApiClient mGoogleApiClient;
Location mLastLocation;
Marker mCurrLocationMarker=null;
TextView tv_loc;
private static View view;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    if(view != null)
    {
        ViewGroup viewGroupParent = (ViewGroup)view.getParent();
        if(viewGroupParent !=null)
        {
            viewGroupParent.removeView(viewGroupParent);
        }
    }
    try{
        view = inflater.inflate(R.layout.my_location,container, false);
    }catch (Exception e)
    {
         /* map is already there, just return view as it is */
        return  view;
    }

    // inflat and return the layout
    //View rootView = inflater.inflate(R.layout.my_location, container, false);

    tv_loc = (TextView)view.findViewById(R.id.textView);
    mapFrag = (SupportMapFragment)getChildFragmentManager().findFragmentById(R.id.map);
    mapFrag.getMapAsync(this);

    return view;

}

En manifiesto agrega estas líneas

    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

y luego usa esta clase

Answer 2

En primer lugar, implemente LocationListener en su Actividad, luego

si necesita mostrar solo un marcador (posición de actualización de Marker), use esto:

private Marker currentPositionMarker = null;

 @Override
    public void onLocationChanged(Location location) {

      LatLng  latLng = new LatLng(location.getLatitude(), location.getLongitude());
        CameraPosition cameraPosition = new CameraPosition.Builder()
                .target(latLng).zoom(14).build();

        // mMap.clear(); // Call if You need To Clear Map
        if (currentPositionMarker == null)
            currentPositionMarker = mMap.addMarker(new MarkerOptions()
                    .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_YELLOW))
                    .position(latLng)
                    .zIndex(20));
        else 
            currentPositionMarker.setPosition(latLng);


        mMap.animateCamera(CameraUpdateFactory
                .newCameraPosition(cameraPosition));
    }

o si quieres agregar un nuevo marcador cada vez:

 @Override
    public void onLocationChanged(Location location) {

        LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
        CameraPosition cameraPosition = new CameraPosition.Builder()
                .target(latLng).zoom(14).build();

        mMap.addMarker(new MarkerOptions()
                .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_YELLOW))
                .position(latLng)
                .zIndex(20));

        mMap.animateCamera(CameraUpdateFactory
                .newCameraPosition(cameraPosition));
    } 

si la ubicación se cambió rápidamente, su aplicación tardaría unos segundos en actualizar su marcador de ubicación

Answer 3

Espero que esta respuesta te ayude. En lugar de usar gps, usa Google Fused Api. Lee aquí la documentación de Fusioned Api y lee esta respuesta. Cómo hacer que el marcador de bus se mueva.

Esto se puede hacer usando CameraPosition, googleMap.animateCamera y la animación del movimiento del marcador usando un interpolador lineal.

Puedes echar un vistazo a este tutorial aquí y a la página correspondiente de github.

Este tutorial usa google maps v2. Espero que esto ayude.

Answer 5

Para animar simplemente llame a este método ( animateMarker ) con la ubicación anterior y la nueva ubicación junto con el objeto Marker

private Marker mCurrentMarker;
private float ZOOMLEVEL=18.0f;
private LatLng previousLatLon;
private Handler mLocalHandler;
private GoogleMap mGoogleMap;

public void animateMarker(final Marker marker, final LatLng toPosition,final LatLng fromPosition) {


        final long duration = 500;
        final Interpolator interpolator = new LinearInterpolator();

        mLocalHandler.post(new Runnable() {
            @Override
            public void run() {
                long elapsed = SystemClock.uptimeMillis() - mStartTime;
                float t = interpolator.getInterpolation((float) elapsed
                        / duration);
                marker.setPosition(toPosition);
                marker.setAnchor(Constants.MAPANCHOR, Constants.MAPANCHOR);
                mGoogleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(toPosition, ZOOMLEVEL));
                if (t < 1.0) {
                    // Post again 16ms later.
                    mLocalHandler.postDelayed(this, 16);
                } else {
                    marker.setVisible(true);
                }
                }
            }
        });
        previousLatLon=toPosition;// reassign the previous location to current location
    }

Answer 6

Puede usar el código a continuación para actualizar la posición del marcador

public void onLocationChanged(Location location) {

    double lattitude = location.getLatitude();
    double longitude = location.getLongitude();

    //Place current location marker
    LatLng latLng = new LatLng(lattitude, longitude);


    if(mCurrLocationMarker!=null){
        mCurrLocationMarker.setPosition(latLng);
    }else{
        mCurrLocationMarker = mGoogleMap.addMarker(new MarkerOptions()
                                .position(latLng)
                                .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_RED))
                                .title("I am here");
    }

    tv_loc.append("Lattitude: " + lattitude + "  Longitude: " + longitude);
    gMap.animateCamera(CameraUpdateFactory.newLatLngZoom(latLng, 15));

    //stop location updates
    if (mGoogleApiClient != null) {
        LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, this);
    }

}

No es necesario borrar el mapa cada vez. Puedes hacerlo mediante el objeto Marker que se devuelve al agregar Marker a Map. Espero que te ayude.

Answer 7

Si aún está buscando la solución, espero que esto https://www.youtube.com/watch?v=WKfZsCKSXVQ lo ayude. Lo he usado en una de mis aplicaciones y me ayuda a animar el marcador desde una ubicación a otra. El código fuente puede ser agarrado aquí https://gist.github.com/broady/6314689 .

Es posible que necesite agregar rotación a su marcador para mostrar la dirección exacta del marcador. A continuación está el bloque de código que estoy usando para encontrar rumbo.

    private float bearingBetweenLatLngs(LatLng begin, LatLng end) {
        Location beginL = convertLatLngToLocation(begin);
        Location endL = convertLatLngToLocation(end);

        return beginL.bearingTo(endL);
    }

Answer 8

utilizar esta

implementar LocationListener ,GoogleMap.OnMyLocationChangeListener en su actividad de mapa

y luego usar el oyente de cambio de ubicación

   @Override
public void onMyLocationChange(Location location) { //mMap.clear //if you want refresh map remove comand
    // Getting latitude of the current location
    double latitude = location.getLatitude();

    // Getting longitude of the current location
    double longitude =location.getLongitude();

    // Creating a LatLng object for the current location
    LatLng latLng = new LatLng(latitude, longitude); //your_text_view.settext(latitude+","+longtitudde)

    // Showing the current location in Google Map
  mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
    mMap.addMarker(new MarkerOptions().icon(BitmapDescriptorFactory.fromResource(R.drawable.destination_marker)).position(latLng).title(maping_status));

    // Zoom in the Google Map
  mMap.animateCamera(CameraUpdateFactory.zoomTo(20));
}
