你需要使用latest/最新的

GoogleApiClient Api

基本上你需要做的是:

private GoogleApiClient mGoogleApiClient;
mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addApi(LocationServices.API)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .build();

然后

@Override
    public void onConnected(Bundle connectionHint) {
        mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
                mGoogleApiClient);
        if (mLastLocation != null) {
            mLatitudeText.setText(String.valueOf(mLastLocation.getLatitude()));
            mLongitudeText.setText(String.valueOf(mLastLocation.getLongitude()));
        }
    }

不要使用LocationListener，它是不准确的，有延迟响应。老实说，这更容易实现。 请阅读文档:https://developers.google.com/android/reference/com/google/android/gms/common/api/GoogleApiClient

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);
}

对于位置检查，您可以使用以下代码。你可以把它放在你的onStart()的主活动和显示警报对话框，如果返回为false。

private boolean isLocationAccurate()
    {
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT)
        {
            String provider = Settings.Secure
                    .getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
            if (provider != null && !provider.contains("gps"))
            {
                return false;
            }
        }
        else
        {
            try
            {
                int status = Settings.Secure
                        .getInt(this.getContentResolver(), Settings.Secure.LOCATION_MODE);
                if (status != Settings.Secure.LOCATION_MODE_HIGH_ACCURACY)
                {
                    return false;
                }
            }
            catch (Settings.SettingNotFoundException e)
            {
                Log.e(TAG, e.getMessage());
            }
        }

        return true;
    }

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);               
                }
            });
}

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。
