How to Customize Material better Spinner?

[pnametala]

I'm trying to customize the view, but my default theme doesn't apply

<com.weiwangcn.betterspinner.library.material.MaterialBetterSpinner android:id="@+id/item_type" android:layout_width="match_parent" android:layout_height="wrap_content" android:hint="@string/item_type_hint" app:met_floatingLabel="normal" android:layout_marginTop="16dp" android:layout_marginLeft="4dp" android:layout_marginRight="4dp" android:layout_marginBottom="4dp" />

None of margins or textColors or other customizations are working.

How can I do that?

Ty,
