要在用户关闭位置共享选项后阻止谷歌服务获取用户地理位置，可以使用Android的GeoLocation API结合FireStore来实现。下面是一个代码示例，演示了如何实现这个功能：

1. 首先，确保在AndroidManifest.xml文件中添加了所需的权限：

2. 在你的Activity或Fragment中，添加以下代码来请求用户位置权限并获取当前位置：

import android.content.pm.PackageManager;
import android.location.Location;
import android.os.Bundle;

import androidx.annotation.NonNull;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityCompat;
import androidx.core.content.ContextCompat;

import com.google.android.gms.location.FusedLocationProviderClient;
import com.google.android.gms.location.LocationCallback;
import com.google.android.gms.location.LocationRequest;
import com.google.android.gms.location.LocationResult;
import com.google.android.gms.location.LocationServices;

public class MainActivity extends AppCompatActivity {

    private static final int PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION = 1;
    private FusedLocationProviderClient fusedLocationProviderClient;
    private LocationCallback locationCallback;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(this);
    }

    private void requestLocationPermissions() {
        if (ContextCompat.checkSelfPermission(this,
                android.Manifest.permission.ACCESS_FINE_LOCATION)
                != PackageManager.PERMISSION_GRANTED) {

            ActivityCompat.requestPermissions(this,
                    new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION},
                    PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION);
        } else {
            startLocationUpdates();
        }
    }

    private void startLocationUpdates() {
        LocationRequest locationRequest = LocationRequest.create();
        locationRequest.setInterval(10000);
        locationRequest.setFastestInterval(5000);
        locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

        locationCallback = new LocationCallback() {
            @Override
            public void onLocationResult(LocationResult locationResult) {
                if (locationResult == null) {
                    return;
                }
                for (Location location : locationResult.getLocations()) {
                    // 处理获取到的位置信息
                    // ...
                }
            }
        };

        fusedLocationProviderClient.requestLocationUpdates(locationRequest,
                locationCallback,
                null);
    }

    private void stopLocationUpdates() {
        fusedLocationProviderClient.removeLocationUpdates(locationCallback);
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        if (requestCode == PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION) {
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                startLocationUpdates();
            } else {
                // 处理未获取到位置权限的情况
                // ...
            }
        }
    }

    @Override
    protected void onResume() {
        super.onResume();
        requestLocationPermissions();
    }

    @Override
    protected void onPause() {
        super.onPause();
        stopLocationUpdates();
    }
}

3. 上述代码中的onLocationResult方法将获取到的位置信息传递给了一个叫做Firestore的位置处理方法。你可以根据自己的需求将位置信息存储到Firestore中。

import com.google.firebase.firestore.FirebaseFirestore;

public class MainActivity extends AppCompatActivity {

    // ...

    private void onLocationResult(LocationResult locationResult) {
        if (locationResult == null) {
            return;
        }
        for (Location location : locationResult.getLocations()) {
            // 将位置信息存储到Firestore中
            FirebaseFirestore db = FirebaseFirestore.getInstance();
            Map locationData = new HashMap<>();
            locationData.put("latitude", location.getLatitude());
            locationData.put("longitude", location.getLongitude());
            db.collection("users")
                    .document("user_id")
                    .set(locationData);
        }
    }

    // ...
}

请注意，上述代码示例只演示了如何获取用户位置并将其存储到Firestore中。如果要在用户关闭位置共享选项后阻止谷歌服务获取用户地理位置，你需要根据自己的需求来处理位置信息。
