android - onLocationChanged() 被调用太多次，即使设备没有移动

Question

我已经在我的 Activity 中实现了 OnLocationChanged(Location location) 作为覆盖方法，如下所示:

@Override
public void onLocationChanged(Location location) {

    mCurrentLocation = location;
    if (wifiSpotList != null) {
        presenter.onLocationUpdated(wifiSpotList, mCurrentLocation);
        centerInLoc(location);
    }
}

问题是，即使设备没有移动，这个方法也会被触发。它总是以毫秒为间隔发生。

调试器通过位置参数获取此日志:

mTime = 1446035851646
mLongitude = -3.6923793
mLatitude = 40.5008861

mTime = 1446035856976
mLongitude = -3.6923596
mLatitude = 40.5008932

mTime = 1446035867327
mLongitude = -3.6923681
mLatitude = 40.5008987

mTime = 1446035877344
mLongitude = -3.6923778
mLatitude = 40.5008949

mTime = 1446035882442
mLongitude = -3.6923734
mLatitude = 40.5008926

...

编辑:

这是初始化 requestLocationUpdates 的代码:

protected void startLocationUpdates() {
    LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
    this.locationUpdatesStarted = true;
}

编辑mLocationRequest:

protected void createLocationRequest() {
    LocationRequest mLocationRequest = new LocationRequest();
    mLocationRequest.setInterval(LOCATION_REQUEST_INTERVAL);
    mLocationRequest.setFastestInterval(LOCATION_REQUEST_FASTEST_INTERVAL);
    mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    this.mLocationRequest = mLocationRequest;
}

方法是因为经\纬度变化而触发的吗？为什么即使设备没有移动它也会触发？我可以限制准确性吗？有什么干净的方法来实现 onLocationChanged() 吗？

setSmallestDisplacement(float smallestDisplacementMeters)

您必须以米为单位设置位置更新之间的最小位移默认为 0。
