在我构建地理围栏的方法中，我收到一个错误ExpirationDuration(NEVER_EXPIRE)并setTransitionTypes(GEOFENCE_TRANSITION_ENTER)指出它们无法解析为变量。为什么会这样？

我的方法：

private void buildGeofence(){
    LatLng geofencePoint = marker.getPosition();
    int radius = 1610;
    Geofence.Builder geofence = new Geofence.Builder();
    geofence.setCircularRegion(geofencePoint.latitude,geofencePoint.longitude, radius);
    geofence.setExpirationDuration(NEVER_EXPIRE);
    geofence.setTransitionTypes(GEOFENCE_TRANSITION_ENTER);
    geofence.setNotificationResponsiveness(0);
    geofence.build();
}

这些常量已在您引用的地理围栏类中声明，因此只需将它们用作geofence.setTransitionTypes(Geofence.GEOFENCE_TRANSITION_ENTER);

是的，所以我忘了声明常量。呸！这是我使用的声明：

long NEVER_EXPIRE = -1;
int GEOFENCE_TRANSITION_ENTER = 1;
