  您可以从IntentService地理围栏事件中获取纬度和经度

  GeofencingEvent geofencingEvent = GeofencingEvent.fromIntent（intent）;

  意图服务是触发地理围栏的地方，所以你将在这里添加引脚：

  public class GeofenceTransitionsIntentService extends IntentService {
  
  protected void onHandleIntent(Intent intent) {
      GeofencingEvent geofencingEvent = GeofencingEvent.fromIntent(intent);
      if (geofencingEvent.hasError()) {
          String errorMessage = GeofenceErrorMessages.getErrorString(this,
                  geofencingEvent.getErrorCode());
          Log.e(TAG, errorMessage);
          return;
      }
  
      // Get the transition type.
      int geofenceTransition = geofencingEvent.getGeofenceTransition();
  
      // Test that the reported transition was of interest.
      if (geofenceTransition == Geofence.GEOFENCE_TRANSITION_ENTER ||
              geofenceTransition == Geofence.GEOFENCE_TRANSITION_EXIT) {
  
          // Get the geofences that were triggered. A single event can trigger
          // multiple geofences.
          List triggeringGeofences = geofencingEvent.getTriggeringGeofences();
  
          // Get the transition details as a String.
          String geofenceTransitionDetails = getGeofenceTransitionDetails(
                  this,
                  geofenceTransition,
                  triggeringGeofences
          );
  
          // Send notification and log the transition details.
          sendNotification(geofenceTransitionDetails);
          Log.i(TAG, geofenceTransitionDetails);
      } else {
          // Log the error.
          Log.e(TAG, getString(R.string.geofence_transition_invalid_type,
                  geofenceTransition));
      }
  }
  

  Android官方文档有一个关于实现地理围栏的很好的教程：

  你可以从GeofencingEvent获得它 .

  protected void onHandleIntent(Intent intent) {
      GeofencingEvent geofencingEvent = GeofencingEvent.fromIntent(intent);
      if (geofencingEvent.hasError()) {
          //TODO: Error handling
  
          return;
      }
  
      Location location = geofencingEvent.getTriggeringLocation();
      double latitude = location.getLatitude();
      double longitude = location.getLongitude();
  }
