Spinner Scrollbar inset or padding

Question

I'm looking to change the style of the scrollbar in my spinner popup view. But changing properties in the xml doesn't do anything to the popup as it's a different view.

<Spinner
        android:id="@+id/countrySpinner"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:background="@drawable/spinner_background"
        android:layoutDirection="rtl"
        android:popupBackground="@drawable/spinner_dropdown_background"
        android:popupElevation="4dp"
        app:popupTheme="@style/PopupTheme"
        app:layout_constraintBottom_toTopOf="@id/citySpinner"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintWidth_percent="0.8" />

This is the style of my spinner. As it's clear, the scrollbar is appearing on top of the corners of the spinner which make it look very off.

Is there anyway to change the style of the scrollbar? Make it more round like the corners. Or at least remove it entirely.

Edit : I managed to remove it from styles. Would still like if there was a way to customize it

Could you please post your xml file – ismail alaoui Apr 17 '19 at 14:22 — ismail alaoui, Apr 17 '19 at 14:22

Spinner does not have a scrollbar.The popup shown by spinner has a scrollbar. So you need to change the properties of the ListView shown by spinner. But ListView itself is not exposed by Spinner by any public methods.

But If you are going to create a custom Spinner, i believe it is easier to implement the whole popup to suit your needs than using reflection.
