GoogleSamples有详细的例子使用最新的FusedLocationProviderApi。 不幸的是，被点赞最多的答案都过时了。

按照下面的例子使用FusedLocationProviderApi实现位置服务

https://github.com/googlesamples/android-play-location/tree/master/LocationUpdates

https://github.com/googlesamples/android-play-location/blob/master/LocationUpdates/app/src/main/java/com/google/android/gms/location/sample/locationupdates/MainActivity.java

自2020年9月23日起，play-services-location版本17.1.0包含了FusedLocationProviderClient.getCurrentLocation()方法，这是获得当前位置的推荐和直接的方法:

返回设备上的单个当前位置固定。与返回缓存位置的getLastLocation()不同，此方法可能导致设备上的活动位置计算。如果能在合理的时间内(几十秒)确定设备位置，将返回一个新的位置，否则将返回null。

关于详细的例子，看看codingjeremy的回答和GitHub上的官方Android位置示例- Current location (Kotlin)。

我已经创建了一个小的应用程序，一步一步的描述，以获得当前位置的GPS坐标。

完整的示例源代码是在获取当前位置坐标，城市名称-在Android。

看看它是如何工作的:

All we need to do is add this permission in the manifest file: <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> And create a LocationManager instance like this: LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); Check if GPS is enabled or not. And then implement LocationListener and get coordinates: LocationListener locationListener = new MyLocationListener(); locationManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, 5000, 10, locationListener); Here is the sample code to do so

/*---------- Listener class to get coordinates ------------- */
private class MyLocationListener implements LocationListener {

    @Override
    public void onLocationChanged(Location loc) {
        editLocation.setText("");
        pb.setVisibility(View.INVISIBLE);
        Toast.makeText(
                getBaseContext(),
                "Location changed: Lat: " + loc.getLatitude() + " Lng: "
                    + loc.getLongitude(), Toast.LENGTH_SHORT).show();
        String longitude = "Longitude: " + loc.getLongitude();
        Log.v(TAG, longitude);
        String latitude = "Latitude: " + loc.getLatitude();
        Log.v(TAG, latitude);

        /*------- To get city name from coordinates -------- */
        String cityName = null;
        Geocoder gcd = new Geocoder(getBaseContext(), Locale.getDefault());
        List<Address> addresses;
        try {
            addresses = gcd.getFromLocation(loc.getLatitude(),
                    loc.getLongitude(), 1);
            if (addresses.size() > 0) {
                System.out.println(addresses.get(0).getLocality());
                cityName = addresses.get(0).getLocality();
            }
        }
        catch (IOException e) {
            e.printStackTrace();
        }
        String s = longitude + "\n" + latitude + "\n\nMy Current City is: "
            + cityName;
        editLocation.setText(s);
    }

    @Override
    public void onProviderDisabled(String provider) {}

    @Override
    public void onProviderEnabled(String provider) {}

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

获得位置更新需要大量的代码在Android，你需要照顾

谷歌播放服务可用性检查， 更新谷歌播放服务，如果它是旧的或不可用 对话框创建GoogleApiClient和它的回调连接，断开等。 停止并释放用于位置更新的资源 处理位置权限场景 检查“位置”服务是否开启 获取最后已知位置也不是那么容易 如果在一定时间后没有得到位置，则退回到最后一个已知位置

为了简化所有这些步骤，我创建了android - easylocation(小型android库)，它将照顾所有这些东西，你可以专注于业务逻辑。

所有你需要的是扩展EasyLocationActivity和这个

requestSingleLocationFix(easyLocationRequest);

or

requestLocationUpdates(easyLocationRequest);

签出示例应用程序和步骤需要在这里https://github.com/akhgupta/Android-EasyLocation

class MyLocation {
    Timer timer1;
    LocationManager lm;
    LocationResult locationResult;
    boolean gps_enabled = false;
    boolean network_enabled = false;

    public boolean getLocation(Context context, LocationResult result) {
        // I use LocationResult callback class to pass location value from
        // MyLocation to user code.
        locationResult = result;
        if (lm == null)
            lm = (LocationManager) context
                    .getSystemService(Context.LOCATION_SERVICE);

        // Exceptions will be thrown if the provider is not permitted.
        try {
            gps_enabled = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
        }
        catch (Exception ex) {
        }
        try {
            network_enabled = lm
                    .isProviderEnabled(LocationManager.NETWORK_PROVIDER);
        }
        catch (Exception ex) {
        }

        // Don't start listeners if no provider is enabled.
        if (!gps_enabled && !network_enabled)
            return false;

        if (gps_enabled)
            lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0,
                    locationListenerGps);
        if (network_enabled)
            lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0,
                    locationListenerNetwork);
        timer1 = new Timer();
        timer1.schedule(new GetLastLocation(), 5000);
        return true;
    }

    LocationListener locationListenerGps = new LocationListener() {
        public void onLocationChanged(Location location) {
            timer1.cancel();
            locationResult.gotLocation(location);
            lm.removeUpdates(this);
            lm.removeUpdates(locationListenerNetwork);
        }

        public void onProviderDisabled(String provider) {
        }

        public void onProviderEnabled(String provider) {
        }

        public void onStatusChanged(String provider, int status, Bundle extras) {
        }
    };

    LocationListener locationListenerNetwork = new LocationListener() {
        public void onLocationChanged(Location location) {
            timer1.cancel();
            locationResult.gotLocation(location);
            lm.removeUpdates(this);
            lm.removeUpdates(locationListenerGps);
        }

        public void onProviderDisabled(String provider) {
        }

        public void onProviderEnabled(String provider) {
        }

        public void onStatusChanged(String provider, int status, Bundle extras) {
        }
    };

    class GetLastLocation extends TimerTask {
        @Override
        public void run() {
            lm.removeUpdates(locationListenerGps);
            lm.removeUpdates(locationListenerNetwork);

            Location net_loc = null, gps_loc = null;
            if (gps_enabled)
                gps_loc = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
            if (network_enabled)
                net_loc = lm
                        .getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

            // If there are both values, use the latest one.
            if (gps_loc != null && net_loc != null) {
                if (gps_loc.getTime() > net_loc.getTime())
                    locationResult.gotLocation(gps_loc);
                else
                    locationResult.gotLocation(net_loc);
                return;
            }

            if (gps_loc != null) {
                locationResult.gotLocation(gps_loc);
                return;
            }
            if (net_loc != null) {
                locationResult.gotLocation(net_loc);
                return;
            }
            locationResult.gotLocation(null);
        }
    }

    public static abstract class LocationResult {
        public abstract void gotLocation(Location location);
    }
}

我希望这对你有所帮助……

我已经发布了一个小的库，可以很容易地在Android中获取位置数据，它甚至照顾到Android M运行时权限。

您可以在这里查看它:https://github.com/julioromano/RxLocation并使用它或其源代码作为实现的示例。
