这是错误:

答案 0 :(得分:1)
更改此行:
mContext = getContext();
对此:
mContext = getActivity();
<强>原因:强>
方法View.getContext()
仅在视图已被夸大时才会运行,因此您在onCreateView
内使用View
时尚未使用该方法,直到return rootView;
行为止到达了。 (虽然您可以在onResume()
)之后使用其他生命周期方法,例如onCreateView
。
因此,请使用此活动,因为Fragment
已经附加到此点,而Context
是此Activity
的{{1}}。如果你仍然在下面发表Fragment
个问题评论,我会编辑答案!
除此之外,请使用类似情况的类名,例如本部分
Context
如果你称之为public class MapPointActivity extends Fragment ....
,那就好了,因为它扩展了MapPointFragment
而不是Fragment
,(它是一个很好的设计),特别是对于未来的参考代码。
