//fragment onCreate method

 @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

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

//fragment onCreateOtionsMenu

  @Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        // TODO your code to hide item here    
        super.onCreateOptionsMenu(menu, inflater);
        menu.clear();
        inflater.inflate(R.menu.home, menu);

    }

//Activity onCreate method

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_home);
         try {
                ViewConfiguration config = ViewConfiguration.get(Home.this);
                Field menuKeyField = ViewConfiguration.class.getDeclaredField("sHasPermanentMenuKey");
                if (menuKeyField != null) {
                    menuKeyField.setAccessible(true);
                    menuKeyField.setBoolean(config, false);
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
}

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

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

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

    <item
        android:id="@+id/action_search"
        android:title="@string/action_search"
        android:icon="@drawable/ic_search"
        app:actionViewClass="android.support.v7.widget.SearchView"
        app:showAsAction="collapseActionView|ifRoom"
        />
