我希望每次用户移动时检索设备位置，但onLocationChanged回调不起作用。有人可以帮帮我吗？这是我管理谷歌地图的活动代码。请注意，我使用了Google库com.google.android.gms.location.LocationListener中的onLocationChanged

答案 0 :(得分：0)
我能够通过在onConnected方法中添加以下代码来解决我的问题：
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
我没有使用LocationServices，因为不推荐使用FusedLocationApi。
