Android 如何在 Spinner 中更改滚动条颜色

Question

How can I change the default color of scrollbar present in the spinner? is it possible to do it on an app level?

<Spinner
        android:id="@+id/location"
        style="@style/Widget.AppCompat.Spinner.Underlined"
        android:layout_width="0dp"
        android:layout_height="45dp"
        android:backgroundTint="@color/input_borde"/>

Answer 1

You can with android:scrollbarThumbVertical="@drawable/youdrawable

For example:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">

    <gradient android:startColor="#66C0C0C0" android:endColor="#66C0C0C0"
        android:angle="45"/>
    <corners android:radius="6dp" />

</shape>

Spinners in Android doesn't have a Scrollbar, the scrollbar exists within the listView maintained inside the Spinner, and has no public access.

There's a run-time way to override it in the link below
