How to style the react-native picker using android styles.xml?

Question

I wanted to know how to set the fontFamily. How to set the color & background color on the Picker.items?

Answer 1

That's because you need to declare the styles inside your AppTheme

<resources>
    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="android:spinnerItemStyle">@style/SpinnerItem</item>
        <item name="android:spinnerDropDownItemStyle">@style/SpinnerDropDownItem</item>
    </style>
    <style name="SpinnerItem">
        <item name="android:textColor">#ffffff</item>
        <item name="android:background">#993399</item>
    </style>
    <style name="SpinnerDropDownItem">
        <item name="android:textColor">#ffffff</item>
        <item name="android:background">#993399</item>
    </style>
</resources>

That's it :)
