java - FusedLocationApi 存在问题，已弃用

Question

我制作了一个谷歌地图应用程序，但当我接受权限时它会关闭。除了 onConnected 方法之外，所有代码都可以。

这里是:

@Override
    public void onConnected(@Nullable Bundle bundle) { //La aplicacion busca la ubicación dentro de este metodo

        myLocationRequest = new LocationRequest();
        myLocationRequest.setInterval(1000); //La información de ubicación se recoge en itnervalos de 1000 milisegundos para no agotar demasiado rapido la bateria
        myLocationRequest.setFastestInterval(1000);

        myLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY); //setPriority se utiliza para controlar el uso de la bateria
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
            LocationServices.FusedLocationApi.requestLocationUpdates(myGoogleApiClient, myLocationRequest, this); //Busca la ubicación de locationrEquest
        }
    }

我猜问题出在 FusedLocationApi.requestLocationUpdates 上，因为它说那里有错误并且文本有删除线。更准确地说，它说“FusedLocationapi”已弃用，我不知道这意味着什么。任何想法？它建议将第三个参数更改为“com.google.android.gms.location.LocationListener”，但如果我这样做，应用程序将无法正常工作。如果我接受许可，它就会突然关闭。

我将完整的代码留在这里，以防您需要检查任何内容:

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback, GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, LocationListener {

    private GoogleMap mMap;
    Location myLastLocation; 
    LocationRequest myLocationRequest;
    GoogleApiClient myGoogleApiClient; 
    Marker myCurrLocationMarker; 

    @Override
    protected void onCreate(Bundle savedInstanceState) { 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            checkLocationPermission();
        }
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map); 
        mapFragment.getMapAsync(this);
    }

    @Override
    public void onMapReady(GoogleMap googleMap) { 
        mMap = googleMap; 
        mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL); 

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { 
            if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) { 
                buildGoogleApiClient();
                mMap.setMyLocationEnabled(true); 
            }
        }
        else {
            buildGoogleApiClient();
            mMap.setMyLocationEnabled(true); 
        }
    }

    protected synchronized void buildGoogleApiClient(){
        myGoogleApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();
        myGoogleApiClient.connect();
    }

    @Override
    public void onConnected(@Nullable Bundle bundle) { 

        myLocationRequest = new LocationRequest();
        myLocationRequest.setInterval(1000); 
        myLocationRequest.setFastestInterval(1000);

        myLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);        if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
            LocationServices.FusedLocationApi.requestLocationUpdates(myGoogleApiClient, myLocationRequest, this); 
        }
    }

    @Override
    public void onConnectionSuspended(int i) {

    }

    @Override
    public void onLocationChanged(Location location) { 

        myLastLocation = location; 
        if (myCurrLocationMarker != null) { 
            myCurrLocationMarker.remove();
        }

        LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());

        MarkerOptions markerOptions = new MarkerOptions();
        markerOptions.position(latLng); 
        markerOptions.title("My Position"); 

        markerOptions.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_MAGENTA)); 
        myCurrLocationMarker = mMap.addMarker(markerOptions); 

        mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng)); 
        mMap.animateCamera(CameraUpdateFactory.zoomTo(11)); 

        if (myGoogleApiClient != null) {
            LocationServices.FusedLocationApi.removeLocationUpdates(myGoogleApiClient, this); 
        }
    }

    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {

    }

    @Override
    public void onProviderEnabled(String provider) {

    }

    @Override
    public void onProviderDisabled(String provider) {

    }

    @Override
    public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {

    }

    public static final int MY_PERMISSIONS_REQUEST_LOCATION = 99;
    public boolean checkLocationPermission() {
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

            if (ActivityCompat.shouldShowRequestPermissionRationale(this,Manifest.permission.ACCESS_FINE_LOCATION)) {
                ActivityCompat.requestPermissions(this, new String[] {Manifest.permission.ACCESS_FINE_LOCATION}, MY_PERMISSIONS_REQUEST_LOCATION);
            }

            else {
                ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, MY_PERMISSIONS_REQUEST_LOCATION);
            }
            return false;
        }
        else {
            return true;
        }
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
        switch (requestCode) {
            case MY_PERMISSIONS_REQUEST_LOCATION: {
                if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {

                        }
                        mMap.setMyLocationEnabled(true);
                    }
                }

                else {
                    Toast.makeText(this, "Permission not given.", Toast.LENGTH_LONG).show();
                }
                return;
            }
        }
    }
}

谢谢您，如果您有任何想法，请告诉我。

我认为与导入有关，尝试将 com.google.android.gms.location.LocationListener 添加到您的 MapsActivity

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback, GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, com.google.android.gms.location.LocationListener {
//
}
