How to get the onLocationResult be triggered all the 30m of displacement in a LocationRequest with the locationCallback?

问题

我不理解，毫秒间隔有效，但最小距离不起作用。如何使onLocationResult在LocationRequest与locationCallback中的30米位移触发？

if (locationRequest == null) {
    locationRequest = new LocationRequest();

    if (drivingtype == Constants.DRIVING_TYPE_BICYCLE) {
        locationRequest.setInterval(Constants.GPS_UPDATE_TIMING_PRECISION);
        locationRequest.setFastestInterval(Constants.GPS_UPDATE_PRECISION);
        locationRequest.setSmallestDisplacement(30f);
    } else {
        locationRequest.setInterval(Constants.GPS_UPDATE_TIMING_PRECISION);
        locationRequest.setFastestInterval((Constants.GPS_UPDATE_PRECISION) / 4);
        locationRequest.setSmallestDisplacement(30f);
    }

    locationRequest.setPriority(LocationRequest.PRIORITY_LOW_POWER);
}

if (locationCallback == null) {
    locationCallback = new LocationCallback() {
        @Override
        public void onLocationResult(LocationResult locationResult) {
            Location location = locationResult.getLastLocation();
            if (location != null) {
                // 处理位置更新
                // 位置已更改。获取坐标并更新地图。
                latitude = location.getLatitude();
                longitude = location.getLongitude();
            }
        }
    };
}

I don't understand, the Interval in milliseconds works well, but the minimum distance doesn't work. How to get the onLocationResult be triggered all the 30m of displacement in a LocationRequest with the locationCallback ?

  if (locationRequest == null) {
            locationRequest = new LocationRequest();

            if (drivingtype == Constants.DRIVING_TYPE_BICYCLE) {

                locationRequest.setFastestInterval(Constants.GPS_UPDATE_PRECISION);
                locationRequest.setSmallestDisplacement(30f);

                locationRequest.setSmallestDisplacement(30f);
            }

根据@Jemshit提供的答案，以下是代码部分的翻译：

// 时间
如果（locationRequest == null）{
locationRequest = LocationRequest.create();

如果（drivingtype == Constants.DRIVING_TYPE_BICYCLE）{
    locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    // locationRequest.setSmallestDisplacement(Constants.GPS_UPDATE_PRECISION);
    locationRequest.setInterval(Constants.GPS_UPDATE_TIMING_PRECISION); // 每分钟更新一次位置
    locationRequest.setFastestInterval(10000);
} else {
    locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    // locationRequest.setSmallestDisplacement(Constants.GPS_UPDATE_PRECISION / 4);
    locationRequest.setInterval(Constants.GPS_UPDATE_TIMING_PRECISION); // 每分钟更新一次位置
    locationRequest.setFastestInterval(10000);
}

}

如果（locationCallback == null）{
locationCallback = new LocationCallback() {
@Override
public void onLocationResult(LocationResult locationResult) {
Location location = locationResult.getLastLocation();
if (location != null) {
// 处理位置更新
// 位置已更改。获取坐标并更新地图。
latitude = location.getLatitude();
longitude = location.getLongitude();
map.getOverlays().clear();

            // 使用新位置更新地图。
            // 例如，使用OsmAnd的功能来移动摄像头或添加标记。
            GeoPoint currentPosition = new GeoPoint(latitude, longitude);
            //moveMapCameraToPosition(currentPosition); // 将摄像头移动到新位置
            animateMapCameraToPosition(currentPosition);

            map.getOverlays().remove(accuracyOverlay);
            int greenColorWithOpacity = Color.argb(128, 0, 255, 0);
            accuracyOverlay = new AccuracyOverlay(new GeoPoint(location), Constants.ACCURACYOVERLAYPRECISION, greenColorWithOpacity);
            map.getOverlayManager().getTilesOverlay().setLoadingBackgroundColor(ContextCompat.getColor(getApplicationContext(), R.color.black));
            map.getOverlays().add(accuracyOverlay);
            map.invalidate();

            // 您还可以在当前位置添加标记

            // 将位置发送到API
            sendPositionToAPI(latitude, longitude);
        }
    }
};

}

// 距离
如果（locationRequest2 == null）{
locationRequest2 = new LocationRequest();

如果（drivingtype == Constants.DRIVING_TYPE_BICYCLE）{
    locationRequest2.setSmallestDisplacement(Constants.GPS_UPDATE_PRECISION);
} else {

}

locationRequest2.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY );

}

}

Looper mainLooper = Looper.getMainLooper();
Looper mainLooper2 = Looper.getMainLooper();

如果（！locationUpdatesEnabled）{
fusedLocationClient.requestLocationUpdates(locationRequest, locationCallback, mainLooper);
fusedLocationClient2.requestLocationUpdates(locationRequest2, locationCallback2, mainLooper2);
locationUpdatesEnabled = true;
}
