Define the Option Menu

Now, we need to create an options menu and arrange for it to be displayed when the user clicks the [MENU] button.
The menu itself can be defined as a small piece of XML. Enter the following as LunchList/res/menu/option.xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/toast"
android:title="Raise Toast"
android:icon="@drawable/toast"
/>
</menu>
This code relies upon an icon stored in LunchList/res/drawable/toast.png. Find something suitable to use, preferably around 32px high.
Then, to arrange for the menu to be displayed, add the following method to LunchList:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
new MenuInflater(this).inflate(R.menu.option, menu);
return(super.onCreateOptionsMenu(menu));
}
Note that you will also need to define imports for android.view.Menu and android.view.MenuInflater for this to compile cleanly. At this point, you can rebuild and reinstall the application. Click the [MENU] button, from either tab, to see the options menu with its icon:
