片段更改时未显示操作栏按钮

Question

I am utilizing the stock Navigation Drawer Activity to host a series of fragments. I am trying to implement seperate ActionBar Buttons when I change to different fragments from within the navigation drawer.

I am running into an issue where the items are not being added to the actionbar directly and are instead being added to the "triple dot" overflow menu as a drop down selection.

What am I doing wrong that the buttons are not becoming available on the actionbar?

JOBFRAGMENT

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    setHasOptionsMenu(true);
    // Inflate the layout for this fragment
    View view = inflater.inflate(R.layout.fragment_jobs, container, false);
    return view;

}

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    // TODO Add your menu entries here
    //inflater = getActivity().getMenuInflater();
    inflater.inflate(R.menu.job_navigation, menu);
    super.onCreateOptionsMenu(menu, inflater);
}

MENU XML

<menu xmlns:android="http://schemas.android.com/apk/res/android" >

<item
    android:id="@+id/action_search"
    android:icon="@drawable/ic_drawer"
    android:showAsAction="ifRoom"
    android:title="@string/action_search"/>
</menu>

Answer 1

您应该将setHasOptionsMenu（true）移到片段的onCreate（）方法中

This post helped solve my problem

Action buttons doesn't show up on Action Bar?

I changed my xml to look like this

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

<item
    android:id="@+id/action_search"
    android:icon="@drawable/ic_drawer"
    android:title="@string/action_search"
    app:showAsAction="always"/>
