Question

我正在尝试使用OldCompany获取用户位置，如下所示：

FusedLocationProviderClient

我在此位置调用中获取位置更新

fusedLocationProviderClient.requestLocationUpdates(mLocationRequest, locationCallback, null);

我读到locationCallback = new LocationCallback() { @Override public void onLocationResult(LocationResult locationResult) { super.onLocationResult(locationResult); for (Location location : locationResult.getLocations()) { // list of locations } } };检索从最旧到最新排序的位置对象列表，我无法理解我想要的只是获取用户位置。

对此有何帮助？

Answer 1

您可以使用locationResult.getLastLocation()获取最新的可用位置。

来自文档：LocationResult.getLastLocation()

public Location getLastLocation ()
    Returns the most recent location 
    available in this result, or null if no 
    locations are available.

Answer 2

您可以使用LocationManager代替FusedLocationProviderClient。它可能会更容易。

    LocationManager manager = (LocationManager) this.getSystemService(LOCATION_SERVICE);
    LocationListener locationListener = new LocationListener() {
        @Override
        public void onLocationChanged(Location location) {
            Log.d("Current location", location.toString());
        }

        @Override
        public void onStatusChanged(String s, int i, Bundle bundle) {

        }

        @Override
        public void onProviderEnabled(String s) {

        }

        @Override
        public void onProviderDisabled(String s) {

        }
    };
    //Checks permission
    if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        return;
    }
    locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);

这将在用户移动时为您提供位置。
