当我将HomePage活动更改为从ListView扩展时，菜单项不再可见。

Question

在我的主页活动中，我的应用程序中有一个菜单，其中包含一个更新按钮，该按钮设置为＆＃34;始终＆＃34;可见，并且注销按钮设置为＆＃34;从不＆＃34;可见。目前主页活动从ActionBarActivity扩展，但是，当我更改活动，因此从listActivity扩展时，菜单不再存在。有解决方案吗？

activity_homepage.xml

<?xml version="1.0"?>
<RelativeLayout tools:context=".MainActivity" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingTop="@dimen/activity_vertical_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:layout_height="match_parent"
android:layout_width="match_parent" xmlns:tools="http://schemas.android.com/tools" xmlns:android="http://schemas.android.com/apk/res/android">
 </RelativeLayout>




menu_homepage.xml

<?xml version="1.0"?>

-<menu tools:context=".MainActivity" xmlns:tools="http://schemas.android.com/tools" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:android="http://schemas.android.com/apk/res/android">

<item android:title="@string/action_settings" app:showAsAction="never" android:orderInCategory="100" android:id="@+id/action_settings"/>

<item android:title="Update" app:showAsAction="always" android:id="@+id/updateStatus"/>

<item android:title="Logout" app:showAsAction="never" android:id="@+id/LogoutUser"/>

</menu>
