Answer 1

创建TextView布局 dropdown_spinner_text.xml：

<?xml version="1.0" encoding="utf-8"?>
<TextView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/spinner_textview"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:textSize="20sp"
    android:textColor="@color/colorBlack"
    android:background="@color/colorWhite"/>

然后将其设置为您的下拉资源。

spinnerAdapter.setDropDownViewResource(R.layout.dropdown_spinner_text);

Answer 2

将声明的项目样式添加到textAppearance

 <style name="ActionBarThemeOverlay" parent="">
    <item name="android:spinnerItemStyle">@style/SpinnerItem</item>
</style>
<style name="SpinnerItem" parent="@android:style/Widget.TextView.SpinnerItem">
    <item name="android:textColor">@color/actionbar_bg_dk</item>
    <item name="android:textAppearance">@style/SpinnerItem.DropDownItem"</item>

</style>

<style name="SpinnerItem.DropDownItem" parent="android:TextAppearance.Widget.TextView.SpinnerItem">
    <item name="android:textColor">@color/White</item> //drop down item text color
    <item name="android:popupBackground">#424242</item>
</style>
