Android create an array of color in xml color

Question

Hi i want to create a viewpager so i follow this tutorial : https://blog.mindorks.com/android-viewpager-in-kotlin. But when i try to set up the array of color in res.colors :

<array name=”bg_color”>
        <item name=”bg_screen1">#f64c73</item>
        <item name=”bg_screen2">#20d2bb</item>
        <item name=”bg_screen3">#3395ff</item>
        <item name=”bg_screen4">#c873f4</item>
    </array>

This doesn't compile, i got Attribute value expected on = of the first line. And i got type attribute should be define on all other lines. I assume that i should define a type of the array, but which type should i use for colors? and how to declare it ?

EDIT

To use it you have to declare and IntArray then select the good position :

val bg_color = resources.getIntArray(R.array.bg_color)
webView.setBackgroundColor(bg_color[pos])

Exemple for a web view where pos is an int

I think you copy paste code from that tutorial and because of that issue happens for " " . Please add below code .

<array name="bg_color">
    <item name="bg_screen1">#f64c73</item>
    <item name="bg_screen2">#20d2bb</item>
    <item name="bg_screen3">#3395ff</item>
    <item name="bg_screen4">#c873f4</item>
</array>

Don't give a name to each row, it's an array, not a map:

 <string-array name=”bg_color”>
            <item>#f64c73</item>
            <item>#20d2bb</item>
            <item>#3395ff</item>
            <item>#c873f4</item>
        </string-array>

String[] colors = getResources.getStringArray(R.array.bg_color);
