将活动上下文传递给片段内的getLastLocation的更好方法

Question

location fragment.Java

LocationActivity activity;

onCreateView(){
    mFusedLocationClient.getLastLocation()
        .addOnSuccessListener(activity, new OnSuccessListener<Location>(){
            @Override
            public void onSuccess(Location location) {
                if(location != null){
                    // update UI here ..
                }
            }
         }
    );
}

onAttach(){
    activity = (LocationActivity) context;
}

这是将活动传递到Google Location API的正确方法吗？如果是这样，为什么？如果有内存泄漏等正当理由请解释一下吗？提前致谢。抱歉懒惰打字！ :)

使用getActivity()在Fragment中获取Activity上下文。

addOnSuccessListener(getActivity(), new OnSuccessListener<Location>(){
    .....
}
