Daher versuche ich, meine Menüelemente aus der ActionBar zu entfernen und sie in einige Variablen zu ändern, die später verwendet werden sollen. Im Folgenden finden Sie einige grundlegende Testcodes, mit denen versucht wird, die Variable während der Erstellung des Optionsmenüs festzulegen. Wenn es startet, stürzt es mit dem Fehler ab:

MainAct, ivity.java

public class MainActivity extends Activity {

    private MenuItem mRefresh;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.main_menu, menu);
        mRefresh = menu.getItem(R.id.refresh);
        return super.onCreateOptionsMenu(menu);
    }
}

main_menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" >
    <item
        android:id="@+id/refresh"
        android:icon="@drawable/ic_action_refresh"
        android:showAsAction="ifRoom"
        android:title="@string/refresh"/>
</menu>

Irgendwelche Ideen, was ich hier falsch mache? Ich muss in der Lage sein, die Menüelemente zu manipulieren, die über das Tippen hinausgehen.
