Adding Menu in Action Bar

I have a Action Bar where i want to add one help button using Menu. I am using Android 3.0. My Menu code is like below:

<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item  
    android:id="@+id/h开发者_运维技巧elp_btn"
    android:icon="@drawable/help"
    android:title="Help"
    android:showAsAction="ifRoom|withText"
/>

Now how can i add this menu in the action bar??

The same way you create regular menus:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.game_menu, menu);
    return true;
}

http://developer.android.com/guide/topics/ui/menus.html#OptionsMenu

Update;

You can inflate a menu like this @override

Put in res/menu/YOUR_MENU.xml

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.YOUR_MENU, menu);
    return true;
}

I know this is a pretty old question, but I'll throw an answer at it anyway. If you're dealing with a Fragment, you'll need to let the system know you'd like to contribute to the action bar or onCreateOptionsMenu will never be called. https://stackoverflow.com/a/10049807/725752

Now with Jetpack Compose , you don't need separate menu XML

Scaffold(
                modifier = Modifier.fillMaxSize(),
                topBar= {
                    TopAppBar(
                        title = {
                            Text(text = "Create New Recipe")
                        },
                        navigationIcon = {
                            IconButton(onClick = { }) {
                                Icon(
                                    imageVector = Icons.Filled.ArrowBack,
                                    contentDescription = "Back"
                                )
                            }
                        },
                        backgroundColor = Color.Blue,
                        contentColor = Color.White,
                        elevation = 2.dp,
                        actions = {
                            IconButton(onClick = {
                                uiController.hideSoftKeyboard()

                                ...
                            }) {
                                Icon(
                                    contentDescription = "Help",
                                    painter = painterResource(R.drawable.help)
                                )
                            }
                        }
                    )
                }, content = {
                    }
                })

Here topBar contains code for Action Bar and actions contains menu button
