getActivity()在Fragment的onCreateView()方法中返回null [英] getActivity() returns null in onCreateView() method of Fragment

问题描述

为什么getActivity()在onCreateView()片段方法中返回null?

Why does getActivity() return null in onCreateView() method of fragment?

推荐答案

在这种情况下，getActivity()返回 null ，因为一旦onActivityCreated()活动方法被获取，则getActivity()将获得活动引用.会被调用，然后在片段的onCreateView()之后调用此方法.

In this case getActivity() is returning null because getActivity() gets the activity reference once the onActivityCreated() method of activity is called and this method is called after onCreateView() of fragment.
