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。

Edit 2022:不要使用这个库，因为该库有内存泄漏，不再支持/更新。

我将推荐使用智能位置库 使用起来非常简单，它很好地包装了位置逻辑。

启动位置服务:

SmartLocation.with(context).location()
    .start(new OnLocationUpdatedListener() { ... });

如果你只想获得一个单一的位置(不是周期性的)，你可以使用oneFix修饰符。例子:

SmartLocation.with(context).location()
    .oneFix()
    .start(new OnLocationUpdatedListener() { ... });

简单的找到写代码在位置方法

public void onLocationChanged(Location location) {
    if (mCurrLocationMarker != null) {
        mCurrLocationMarker.remove();
    }


    //Place current location marker
    LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
    MarkerOptions markerOptions = new MarkerOptions();
    markerOptions.position(latLng);
    markerOptions.title("Current Position");
    markerOptions.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_RED));
    mCurrLocationMarker = mMap.addMarker(markerOptions);

    //move map camera
    mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
    mMap.animateCamera(CameraUpdateFactory.zoomTo(18));

    PolylineOptions pOptions = new PolylineOptions()
            .width(5)
            .color(Color.GREEN)
            .geodesic(true);
    for (int z = 0; z < routePoints.size(); z++) {
        LatLng point = routePoints.get(z);
        pOptions.add(point);
    }
    line = mMap.addPolyline(pOptions);
    routePoints.add(latLng);
}

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) {}
}

获取位置的最佳方法如下所示

// put dependancy
 implementation 'com.google.android.gms:play-services-location:11.0.4'

// PUT permissions in Menifest
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> 


// create a Java file as below

public class SingleShotLocationProvider {

  public static interface LocationCallback {
      public void onNewLocationAvailable(GPSCoordinates location);
  }

   // calls back to calling thread, note this is for low grain: if you want higher precision, swap the
   // contents of the else and if. Also be sure to check gps permission/settings are allowed.
   // call usually takes <10ms

  public static void requestSingleUpdate(final Context context, final LocationCallback callback) {
    final LocationManager locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
    boolean isNetworkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
    if (isNetworkEnabled) {
        Criteria criteria = new Criteria();
        criteria.setAccuracy(Criteria.ACCURACY_COARSE);
        if (ActivityCompat.checkSelfPermission(context, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED &&
                ActivityCompat.checkSelfPermission(context, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

            return;
        }
        locationManager.requestSingleUpdate(criteria, new LocationListener() {
            @Override
            public void onLocationChanged(Location location) {
                callback.onNewLocationAvailable(new GPSCoordinates(location.getLatitude(), location.getLongitude()));
            }

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

            @Override
            public void onProviderEnabled(String provider) {
            }

            @Override
            public void onProviderDisabled(String provider) {
            }
        }, null);
     } else {
        boolean isGPSEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
        if (isGPSEnabled) {
            Criteria criteria = new Criteria();
            criteria.setAccuracy(Criteria.ACCURACY_FINE);
            locationManager.requestSingleUpdate(criteria, new LocationListener() {
                @Override
                public void onLocationChanged(Location location) {
                    callback.onNewLocationAvailable(new GPSCoordinates(location.getLatitude(), location.getLongitude()));
                }

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


  // consider returning Location instead of this dummy wrapper class
  public static class GPSCoordinates {
     public float longitude = -1;
     public float latitude = -1;

     public GPSCoordinates(float theLatitude, float theLongitude) {
        longitude = theLongitude;
        latitude = theLatitude;
     }

     public GPSCoordinates(double theLatitude, double theLongitude) {
        longitude = (float) theLongitude;
        latitude = (float) theLatitude;
     }
  }

}
// FILE FINISHED


// FETCH LOCATION FROM ACTIVITY AS BELOW
public void getLocation(Context context) {
    MyApplication.log(LOG_TAG, "getLocation() ");

    SingleShotLocationProvider.requestSingleUpdate(context,
            new SingleShotLocationProvider.LocationCallback() {
                @Override
                public void onNewLocationAvailable(SingleShotLocationProvider.GPSCoordinates loc) {
                    location = loc;
                    MyApplication.log(LOG_TAG, "getLocation() LAT: " + location.latitude + ", LON: " + location.longitude);               
                }
            });
