I can not see items in the app bar

Question

I tried everything, I can not see items in my action bar, can someone help me?

Here is my java code:

public class mActivity extends AppCompatActivity {

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(myLayout);


    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar_frontend);
    setSupportActionBar(toolbar);

    }

@Override
public boolean onCreateOptionsMenu(Menu menu) {

    getMenuInflater().inflate(R.menu.main_search, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    int id = item.getItemId();

    if (id == R.id.action_logout) {

        Intent activity2 = new Intent(mActivity.this, LoginPage.class);
        startActivity(activity2);

    }

    if (id == R.id.action_search) {

        //toast

    }


    return super.onOptionsItemSelected(item);
 }


}                              

This is my xml code:

<android.support.design.widget.CoordinatorLayout     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"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:background="#DDDDDD"

>
<android.support.design.widget.AppBarLayout
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:theme="@style/AppTheme.AppBarOverlay">

<android.support.v7.widget.Toolbar
          android:id="@+id/toolbar_frontend"
          android:layout_width="match_parent"
          android:layout_height="?attr/actionBarSize"
          android:background="?attr/colorPrimary"
          app:popupTheme="@style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>




<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/right_drawer_frontend"
    android:layout_width="match_parent"
    android:layout_height="match_parent">


<RelativeLayout      xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"      android:layout_height="match_parent"
        android:background="#DDDDDD"
        android:layout_margin="5dp"
        >

        //...

</RelativeLayout>



<android.support.design.widget.NavigationView
        android:id="@+id/nav_view_right_frontend"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="end"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header_right_customer"
        app:menu="@menu/menu_right_customer" />




 </android.support.v4.widget.DrawerLayout>



 <android.support.design.widget.FloatingActionButton
    //...
 />

 </android.support.design.widget.CoordinatorLayout>

And this is my xml menu code:

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

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

<item android:id="@+id/action_search"
    android:title="Search..."
    android:icon="@drawable/ic_search_black_24dp"
    android:showAsAction="collapseActionView|ifRoom"
    android:actionViewClass="android.widget.SearchView" />

</menu>

I have only a "black" appbar and that's ok but I can't see items in it. I appreciate any help. Thanks in advance.

ah search is an action VIew, you need to initialise that in the onCreateOptionsMenu to do that add these lines to your onCreateOptionsMenu function

MenuItem searchItem = menu.findItem(R.id.action_search); 
SearchView  searchView = (SearchView) MenuItemCompat.getActionView(searchItem);

To show the Search action as an Icon always set showAsAction attribute to always like this

android:showAsAction="collapseActionView|always"
