Android action bar overflow menu not displayed in portrait mode

问题

I have a standard Android action bar (I'm not using the compatibility library) with a SearchView and a handful of text-only menu items. I'd like to have the SearchView always expanded and the remaining items in the overflow menu. The code I have so far works fine on a tablet and on my Nexus 5 in landscape mode, but when the phone is in portrait mode, the overflow menu isn't displayed. If I add the collapseActionView attribute to the SearchView, the overflow menu is properly displayed, but I'd like to keep the search widget fully expanded.

Here's the XML for my options menu:

<menu xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:id="@+id/menu_search"
          android:icon="@android:drawable/ic_menu_search"
          android:title="@string/search"
          android:showAsAction="ifRoom"
          android:actionViewClass="android.widget.SearchView" />
    <item android:id="@+id/action_clear_history"
          android:title="@string/action_clear_history"
          android:showAsAction="never"/>
    <item android:id="@+id/action_feedback"
          android:title="@string/action_feedback"
          android:showAsAction="never"/>
    <item android:id="@+id/action_about"
          android:title="@string/action_about"
          android:showAsAction="never"/>
</menu>

And here's my onCreateOptionsMenu code:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    if (!mNavigationDrawerFragment.isDrawerOpen()) {
        getMenuInflater().inflate(R.menu.options_menu, menu);
        SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        SearchView searchView = (SearchView) menu.findItem(R.id.menu_search).getActionView();
        searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
        searchView.setIconifiedByDefault(false);
        restoreActionBar();
        return true;
    }
    return super.onCreateOptionsMenu(menu);
}

Here's a screenshot of landscape mode, working as intended:

And here's portrait mode, with the overflow menu missing:

Can anyone point me in the right direction?

    </item>    
</menu>

I've added an item which holds a reference to overflow sub menu you can try this, if wanted, or can ask doubt about it. and ic_overflow icon could be

I had similar issue, usefull SO I have found was this : SearchView taking all the space in the new ActionBarCompat, so the solution is to add SearchView manually from code, and not from you menu layout.

here is some code I am using with success on api 19 in portrait, in fragment with support actionbar:

public void initSearchView() {
    searchView = new SearchView(getActionBarHelper().getThemedContext());
    searchView.setIconifiedByDefault(false);

    ActionBar.LayoutParams layoutParams = new ActionBar.LayoutParams(
        ActionBar.LayoutParams.MATCH_PARENT,
        ActionBar.LayoutParams.WRAP_CONTENT, Gravity.RIGHT
        | Gravity.CENTER_VERTICAL);
    searchView.setLayoutParams(layoutParams);

   getActionBarHelper().setCustomView(searchView);
   getActionBarHelper().setDisplayShowCustomEnabled(true);

   searchView.setOnQueryTextListener(mOnQueryTextListener);
   searchView.clearFocus();
   searchView.setImeOptions(EditorInfo.IME_FLAG_NO_EXTRACT_UI);
}

  protected ActionBar getActionBarHelper() {
    return ((ActivityBase) getActivity()).getSupportActionBar();
  }

I call initSearchView in onCreateView(),

try

try {
    ViewConfiguration config = ViewConfiguration.get(this);
    Field menuKeyField = ViewConfiguration.class
            .getDeclaredField("sHasPermanentMenuKey");
    if (menuKeyField != null) {
        menuKeyField.setAccessible(true);
        menuKeyField.setBoolean(config, false);
    }
} catch (Exception e) {
    e.printStackTrace();
}
