<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
</menu>
Se invece, aggiungessimo:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:title="Item" />
</menu>
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:title="Aggiorna"
/>
</menu>
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:title="Aggiorna"
android:id="@+id/aggiorna"
/>
</menu>
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:title="Aggiorna"
android:id="@+id/aggiorna"
android:orderInCategory="100"
/>
</menu>
icona creata. Quindi?
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item android:title="Aggiorna"
android:id="@+id/aggiorna"
android:orderInCategory="100"
app:showAsAction="ifRoom"
android:icon="@drawable/aggiorna"
/>
</menu>
