How to add Options Menu to Fragment in Android

If you find the onCreateOptionsMenu(Menu menu, MenuInflater inflater) method is not being invoked, make sure you call the following from the Fragment's onCreate(Bundle savedInstanceState) method:

setHasOptionsMenu(true)

If you need a menu to refresh a webview inside a specific Fragment, you can use:

Fragment:

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

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {

    // TODO Add your menu entries here
    inflater.inflate(R.menu.menu, menu);
    super.onCreateOptionsMenu(menu, inflater);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    case R.id.exit:
        System.exit(1);
        break;

    case R.id.refresh:
        webView.reload();
        break;
    }
    return true;

}

menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/exit" android:title="Exit" android:icon="@drawable/ic_action_cancel" />
    <item android:id="@+id/refresh" android:title="Refresh" android:icon="@drawable/ic_action_refresh" />
</menu>

I had the same problem, but I think it's better to summarize and introduce the last step to get it working:

1. Add setHasOptionsMenu(true) method in your Fragment's onCreate(Bundle savedInstanceState) method.

2. Override onCreateOptionsMenu(Menu menu, MenuInflater inflater) (if you want to do something different in your Fragment's menu) and onOptionsItemSelected(MenuItem item) methods in your Fragment.

3. Inside your onOptionsItemSelected(MenuItem item) Activity's method, make sure you return false when the menu item action would be implemented in onOptionsItemSelected(MenuItem item) Fragment's method.

An example:

Activity

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

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {

        case R.id.activity_menu_item:

            // Do Activity menu item stuff here
            return true;

        case R.id.fragment_menu_item:

            // Not implemented here
            return false;
        default:
            break;
    }

    return false;
}

Fragment

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

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    // Do something that differs the Activity's menu here
    super.onCreateOptionsMenu(menu, inflater);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {

        case R.id.activity_menu_item:

            // Not implemented here
            return false;
        case R.id.fragment_menu_item:

            // Do Fragment menu item stuff here
            return true;

        default:
            break;
    }

    return false;
}

Call the super method:

Java:

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

    @Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        // TODO Add your menu entries here
        super.onCreateOptionsMenu(menu, inflater);
    }

Kotlin:

    override fun void onCreate(savedInstanceState: Bundle) {
        super.onCreate(savedInstanceState)
        setHasOptionsMenu(true)
    }

    override fun onCreateOptionsMenu(menu: Menu, inflater: MenuInflater) {
        // TODO Add your menu entries here
        super.onCreateOptionsMenu(menu, inflater)
    }

Put log statements in the code to see if the method is not being called or if the menu is not being amended by your code.

Also ensure you are calling setHasOptionsMenu(boolean) in onCreate(Bundle) to notify the fragment that it should participate in options menu handling.
