Implement LocationListener :

@Override
public void onLocationChanged(Location location) {

}

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

}

@Override
public void onProviderEnabled(String provider) {

}

@Override
public void onProviderDisabled(String provider)
{
    if (provider.equals(LocationManager.GPS_PROVIDER))
    {
        showGPSDiabledDialog();
    }
}

Show dialog to open Settings:

public void showGPSDiabledDialog() {
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("GPS Disabled");
    builder.setMessage("Gps is disabled, in order to use the application properly you need to enable GPS of your device");
    builder.setPositiveButton("Enable GPS", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            startActivityForResult(new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS), GPS_ENABLE_REQUEST);
        }
    }).setNegativeButton("No, Just Exit", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {

        }
    });
    mGPSDialog = builder.create();
    mGPSDialog.show();
}

In your onCreate Method call :

LocationManager mLocationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
    return;
}
mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);

And override onActivityResult method to test if the user activated GPS correctly.

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == GPS_ENABLE_REQUEST) {
        if (mLocationManager == null) {
            mLocationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
        }

        if (!mLocationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
            showGPSDiabledDialog();
        }
    } else {
        super.onActivityResult(requestCode, resultCode, data);
    }
}

Full example :

/**
 * Function to check if best network provider
 * @return boolean
 * */
public boolean canGetLocation() {
    return this.canGetLocation;
}

/**
 * Function to show settings alert dialog
 * */
public void showSettingsAlert(){
    AlertDialog.Builder alertDialog = new AlertDialog.Builder(mContext);

    // Setting Dialog Title
    alertDialog.setTitle("GPS is settings");

    // Setting Dialog Message
    alertDialog.setMessage("GPS is not enabled. Do you want to go to settings menu?");

    // Setting Icon to Dialog
    //alertDialog.setIcon(R.drawable.delete);

    // On pressing Settings button
    alertDialog.setPositiveButton("Settings", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog,int which) {
            Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
            mContext.startActivity(intent);
        }
    });

    // on pressing cancel button
    alertDialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
        dialog.cancel();
        }
    });

    // Showing Alert Message
    alertDialog.show();
}

Here is the doc : http://www.androidhive.info/2012/07/android-gps-location-manager-tutorial/ (copied point 7)

Check this official document: https://developer.android.com/training/permissions/requesting.html Also, the accepted answer on this thread is the one I used to prompt for storage write access and it works perfectly fine: Android 6.0 Marshmallow. Cannot write to SD Card You only need to workout the keywords for location access.

        public class MainActivity extends AppCompatActivity
                implements NavigationView.OnNavigationItemSelectedListener ,OnMapReadyCallback,LocationListener{

     protected static final String TAG = "MainActivity";
        protected static final int REQUEST_CHECK_SETTINGS = 0x1;

        Marker mCurrLocationMarker;
        GoogleMap mgooglemap;
        private LocationManager locationManager;


@Override
    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 = mgooglemap.addMarker(markerOptions);


        //move map camera
        mgooglemap.animateCamera(CameraUpdateFactory.newLatLngZoom(latLng,16));
mgooglemap.getMaxZoomLevel();
      //  locationManager.removeUpdates(this);
    }

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

    }

    @Override
    public void onProviderEnabled(String provider) {

    }

    @Override
    public void onProviderDisabled(String provider) {
        Toast.makeText(MainActivity.this, "Please Enable GPS", Toast.LENGTH_LONG).show();
    }

The onProviderDisabled() of the above code will provide you the required flow.
