我想获取CurrentLocation而不是LastKnownLocation

Question

所以我做了这个代码，它是工作的，但位置只能得到检索，如果我打开谷歌地图之前启动应用程序，我想做的是让应用程序检测我的当前位置，而不是最后已知的位置。我发现有一个名为getCurrentLocation（）的方法可以用来检索我的位置，但我不知道在参数中放什么。请帮帮我.这是我的密码

private void getLocation（）{

    //Check Permissions again
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {

        if (ActivityCompat.checkSelfPermission(Reclamation.this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(Reclamation.this,

                Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

            requestPermissions(new String[]{
                    Manifest.permission.ACCESS_COARSE_LOCATION,
                    Manifest.permission.ACCESS_FINE_LOCATION,
                    Manifest.permission.INTERNET}, REQUEST_PERMISSION_LOCATION);

        }
        
        locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
        Location LocationGps = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
        Location LocationNetwork = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
        Location LocationPassive = locationManager.getLastKnownLocation(LocationManager.PASSIVE_PROVIDER);




        if (LocationGps != null) {
            double lat = LocationGps.getLatitude();
            double longi = LocationGps.getLongitude();
            latitude = String.valueOf(lat);
            longitude = String.valueOf(longi);

        } else if (LocationNetwork != null) {
            double lat = LocationNetwork.getLatitude();
            double longi = LocationNetwork.getLongitude();

            latitude = String.valueOf(lat);
            longitude = String.valueOf(longi);

        } else if (LocationPassive != null) {
            double lat = LocationPassive.getLatitude();
            double longi = LocationPassive.getLongitude();

            latitude = String.valueOf(lat);
            longitude = String.valueOf(longi);
            Toast.makeText(Reclamation.this, "Passive is not null :D", Toast.LENGTH_SHORT).show();


        } else {
            Toast.makeText(Reclamation.this, "Can't Get Your Location", Toast.LENGTH_SHORT).show();
        }

        Intent intent = new Intent(Reclamation.this, SetLocation.class);
        intent.putExtra("latt", latitude);
        intent.putExtra("lonn", longitude);
        Toast.makeText(Reclamation.this, latitude + " " + longitude, Toast.LENGTH_SHORT).show();
        startActivityForResult(intent, 3);


    }
}

与

    api 'com.google.android.gms:play-services-location:18.0.0'

您可以使用此方法

FusedLocationProviderClient fusedLocationClient;
FusedLocationProviderClient locationProviderClient = LocationServices.
                                       getFusedLocationProviderClient(this);

//LOCATION AVAILABILITY

fusedLocationClient
            .getLocationAvailability()
            .addOnSuccessListener(new OnSuccessListener<LocationAvailability>() {
                @Override
                public void onSuccess(LocationAvailability locationAvailability) {
                    
                }
            })
            .addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    
                }
            });

//LAST LOCATION

 fusedLocationClient.getLastLocation()
            .addOnSuccessListener(new OnSuccessListener<Location>() {
                @Override
                public void onSuccess(Location location) {
                    
                }
            })
            .addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    
                }
            });

//AND MORE...

fusedLocationClient
            .requestLocationUpdates()
