How to style Android spinner popup?

Question

I have set

<item name="android:spinnerMode">dialog</item>

and so when I tap the spinner, I get a popup. But that popup is grey with white text and I can't seem to change any of the colors. How do I style this dialog?

I tried the following with some crazy temporary colors to see what changes but nothing changes.

<style name="AppTheme" parent="AppBaseTheme">
    <item name="android:dialogTheme">@style/SpinnerDialog</item>
    <item name="android:alertDialogTheme">@style/SpinnerAlertDialog</item>
</style>

<style name="SpinnerDialog" parent="Theme.AppCompat.Light.Dialog">
    <item name="android:popupBackground">#ff00ff</item>
    <item name="colorPrimary">#ff00ff</item>
    <item name="colorPrimaryDark">#ffff00</item>
    <item name="colorAccent">#ff0000</item>
</style>

<style name="SpinnerAlertDialog" parent="Theme.AppCompat.Dialog">
    <item name="colorPrimary">#00ffff</item>
    <item name="colorPrimaryDark">#00ff00</item>
    <item name="colorAccent">#0000ff</item>
</style>

There are a bunch of similar questions, but they all either deal with dropdowns or ancient versions of Android or just don't work.

Answer 1

Instead of using theme or style.xml for changing the popup background color of dialog.

Why not try this?? In your layout xml

 <Spinner
    android:id="@+id/spinner1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:spinnerMode="dialog"
    android:popupBackground="#yourcolor"/>

Since you tried adding theme it changes nothing.This will be easy to achieve..isn't it??

Hope this helps!!!
