How do I change the color of a selected item on a ListView?

I found out that I have to customize it directly on Android.

To use the theme I changed Droid/Properties/AssemblyInfo.cs adding:

[assembly: Application(Theme = "@style/AppStyle.Light")]

And I created some files on:

Droid\Resources\values

colors.xml contains the color definitions for my theme:

<?xml version="1.0" encoding="utf-8" ?><resources>  <color name="ListViewSelected">#96BCE3</color>  <color name="ListViewHighlighted">#E39696</color></resources>

styles.xml contains the theme settings:

<?xml version="1.0" encoding="utf-8" ?><resources>  <style name="AppStyle.Light" parent="android:style/Theme.Material.Light.DarkActionBar">    <item name="android:colorPressedHighlight">@color/ListViewSelected</item>    <item name="android:colorLongPressedHighlight">@color/ListViewHighlighted</item>    <item name="android:colorFocusedHighlight">@color/ListViewSelected</item>    <item name="android:colorActivatedHighlight">@color/ListViewSelected</item>    <item name="android:activatedBackgroundIndicator">@color/ListViewSelected</item>  </style></resources>

Using these names I can change the listview style.

android:colorPressedHighlightandroid:colorLongPressedHighlightandroid:colorFocusedHighlightandroid:colorActivatedHighlightandroid:activatedBackgroundIndicator

Late to the party but the problem has been solved in the CollectionView https://docs.microsoft.com/en-us/xamarin/xamarin-forms/user-interface/collectionview/selection#change-selected-item-color
