How to change SearchView elements' color?

To change the color of SearchView elements in Kotlin, you can follow these steps:

1. Create a new XML file in the res/color folder to define the colors you want to use, for example:

<resources>
    <color name="searchViewTextColor">#FFFFFF</color>
    <color name="searchViewHintColor">#CCCCCC</color>
</resources>

1. In the styles.xml file, define a new style for the SearchView using the colors you defined:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Other style attributes -->
    <item name="searchViewStyle">@style/MySearchViewStyle</item>
</style>

<style name="MySearchViewStyle" parent="Widget.AppCompat.SearchView">
    <item name="android:textColor">@color/searchViewTextColor</item>
    <item name="android:textColorHint">@color/searchViewHintColor</item>
</style>

1. Apply the AppTheme style to your application in the AndroidManifest.xml file:

<application
    android:theme="@style/AppTheme">
    <!-- Other application attributes -->
</application>

1. In your activity or fragment, find the SearchView and set the background tint using the colors you defined:

val searchView = findViewById<SearchView>(R.id.searchView)
val searchPlateId = searchView.context.resources.getIdentifier("android:id/search_plate", null, null)
val searchPlate = searchView.findViewById<View>(searchPlateId)
searchPlate.setBackgroundColor(ContextCompat.getColor(this, R.color.searchViewBackgroundColor))

These steps will allow you to change the color of SearchView elements in your Kotlin application.
