Android options menu not displaying

Question

I'm new to Android and I've been trying to add a simple add button as mentioned below

list_menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item 
        android:id="@+id/menu_insert"
        android:icon="@android:drawable/ic_menu_add"
        android:title="@string/menu_insert"              
    />     
</menu>

MyActivity.java

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        super.onCreateOptionsMenu(menu);
        getMenuInflater().inflate(R.menu.list_menu, menu);

        return true;  
    }

I read in Dummies series book that ic_menu_add is already there in resources and I don't need to add it, but when I run this code it does not display. I've tried to add a custom icon with same name still there is no button. Can someone help me with it please.

If you use a fragment then you need this in onCreate():

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