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?
