无法重写ListFragment中的onCreateOptionsMenu [英] Unable to override onCreateOptionsMenu in ListFragment

问题描述

我创建了一款支持手机和平板电脑版本的应用程序，因此我使用了android-support-v4.jar库。

I created an app that supports both phone and tablet version so i use the android-support-v4.jar library.

我的活动扩展了ListFragment，我尝试覆盖onCreateOptionsMenu（Menu Menu，MenuInflater inflater），如下面的链接所示： http://developer.android.com/resources/samples/Support4Demos /src/com/example/android/supportv4/app/FragmentMenuSupport.html

My activity extends the ListFragment and I tried to override the onCreateOptionsMenu(Menu menu, MenuInflater inflater), as in the following link: http://developer.android.com/resources/samples/Support4Demos/src/com/example/android/supportv4/app/FragmentMenuSupport.html

我以前叫setHasOptionsMenu。

I previously called setHasOptionsMenu.

不幸的是，我似乎无法重写onCreateOptionsMenu（）。

Unfortunately, it seems that I cannot override onCreateOptionsMenu().

这是错误信息：

This is the error message:

类型MyFragment的onCreateOptionsMenu（Menu menu，MenuInflater inflater）方法必须覆盖或实现超类型方法。

The method onCreateOptionsMenu(Menu menu, MenuInflater inflater) of type MyFragment must override or implements a supertype method.

我做到了这一点：

And I did that with:

Public class MyFragment extends ListFragment

推荐答案

确认的进口从兼容性库，而不是从SDK本身。

Make sure the imports are from the compatibility library and not from the SDK itself.
