Separator color always black

[jkwiecien]

Not sure if it's onli API29, but that's my target. Separator color is always black no matter what color I set it, however, it appears right on the layout editor - just not on the actual build. I'm setting color in xml.

I reproduced it at sample project just by modyfing activity_main.xml quickly:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_margin="30dp"
    android:gravity="center"
    android:orientation="vertical">

    <Button
        android:id="@+id/default_number_picker_button"
        style="@style/Button"
        android:text="@string/alert_default_title" />

    <Button
        android:id="@+id/simple_number_picker_button"
        style="@style/Button"
        android:layout_marginTop="16dp"
        android:text="@string/alert_simple_title" />

    <Button
        android:id="@+id/custom_number_picker_button"
        style="@style/Button"
        android:layout_marginTop="16dp"
        android:text="@string/alert_custom_title" />

    <com.github.stephenvinouze.materialnumberpickercore.MaterialNumberPicker
        android:layout_width="70dp"
        android:layout_height="wrap_content"
        app:mnpSeparatorColor="@android:color/holo_orange_dark"
        app:mnpTextSize="17dp" />
</LinearLayout>

Did further investigation and looks like it's related to one of these, which are newer in mine:

• ANDROID_BUILD_SDK_VERSION=29
• distributionUrl=https://services.gradle.org/distributions/gradle-6.5-bin.zip
• implementation 'androidx.appcompat:appcompat:1.2.0'

I also head same problem, when used picker in XML on android API 33.
