It's easy to disable key previews: just call setPreviewEnabled(false) and these annoying tiny previews won't show up anymore. But if I attach a popup keyboard to any key then these previews will show up inside that popup:
qwerty.xml:
<Key android:codes="101" 
    android:keyLabel="E" 
    android:popupKeyboard="@xml/popup"
   android:keyTextSize="60sp"/>
popup.xml:
<Row>
    <Key android:codes="-10000"
        android:keyLabel="test"
        android:keyOutputText="test"/>
</Row>
<Row>
    <Key android:codes="-10001"
        android:keyLabel="test2"
        android:keyOutputText="test2"/>
</Row>
Can't post images, but if I long press letter 'E' and then press test or test2 button they will show that white key preview.
Is there any way to disable these key previews too?
